Abstract
Objective: The aim of this study was to investigate the effects of 3 Tesla (3T) magnetic resonance imaging (MRI) noise on cochlear functions. Methods: The distortion product otoacoustic emission (DPOAE) test was applied to patients who were scheduled to have 3T MRI in the tertiary care center. Patients who revealed emission amplitudes at all frequencies (1, 1.5, 2, 3, 4, 6, and 8 kHz) in the DPOAE test before MRI were included in the study. After MRI, the DPOAE test was performed twice on 17 patients (33 ears) (immediately after MRI and 30 minutes after MRI). The changes in the results of the tests taken before MRI (pre-MRI), immediately after MRI (post-MRI 1), and at 30 minutes after MRI (post-MRI 2) in the DPOAE amplitudes at all frequencies were compared statistically. Results: There was a significant difference between pre-MRI, post-MRI 1, and post-MRI 2 measurements at 3, 6, and 8 kHz. In pairwise comparisons; post-MRI 1 was statistically lower than post-MRI 2 at 3 kHz, and post-MRI 1 was statistically lower than pre-MRI and post-MRI 2 at 6 and 8 kHz. In addition, post-MRI 2 was significantly lower than pre-MRI at 8 kHz. Conclusion: According to these results, 3T MRI noise does not have any permanent negative impact on hearing functions. It can only cause DPOAE amplitude changes at high frequencies. This is a clinically negligible effect. Therefore, it can be considered that the 3T MRI examination with protective headphones does not cause any adverse side effects in terms of hearing functions.

Relationship between acute phase reactants and prognosis in patients with or without COVID-19 pneumonia. Rev Inst Med Trop Sao Paulo 2021; 63:e51. [PMID: 34190953 PMCID: PMC8231967 DOI: 10.1590/s1678-9946202163051] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2021] [Accepted: 05/10/2021] [Indexed: 01/22/2023] Open
Abstract
In December 2019, several cases of pneumonia of unknown origin were reported in
the city of Wuhan, province of Hubei, China. The pathogen was named as severe
acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and the disease was named
coronavirus disease 2019 (COVID-19). Acute phase reactans (APRs) are critical in
the early diagnosis, treatment, and for monitoring the progression of COVID-19.
Seventy two patients were included in the study and infections confirmed by
real-time reverse transcription polymerase chain reaction. Clinical parameters,
the level of APFs and D-dimer were assessed and results were retrived from the
patients’ medical records. Chest computed tomography (CT) findings were
described for each patient and they were divided into two groups, with or
without COVID-19 pneumonia. The correlation between APRs and CT findings and the
patients’ prognosis were evaluated. Twenty eight (38.8%) of the 72 patients were
female and 44 (61.2%) were male. The most common symptom was cough (43%) and the
most common associated chronic disease was hypertension (12.5%). Thirty (41.6%)
patients had completely normal chest CT, while 42 (58.4%) patients had typical
findings in terms of COVID-19 pneumonia. C reactive protein (CRP), lactate
dehydrogenase (LDH), erythrocyte sedimentation rate (ESR), ferritin,
procalcitonin and D-Dimer levels were statistically significantly higher in
patients with pneumonia than in those without pneumonia and these parameters
were also statistically significantly higher in patients with severe illness. In
conclusion, CRP, LDH, ESR, ferritin, and D-Dimer were associated with severe
COVID-19 pneumonia. These biomarkers can be used to evaluate the prognosis to
predict the clinical course of disease, allowing a proper management and
treatment of the patients.

Abstract
Extramedullary plasmacytoma (EMP) is a plasma cell neoplasm of soft tissue without bone marrow involvement or other systemic characteristics of multiple myeloma. Approximately 80-90% of EMPs involve the head and neck region, especially in the nasal cavity, paranasal sinuses, tonsillar fossa, and oral cavity. An EMP of the larynx is extremely rare and is a locally destructive lesion without systemic spread. Clinical features vary depending on the tumor location. A diagnosis is established by histopathology, immunohistochemistry, and a systemic survey to exclude systemic plasma cell proliferative diseases. Extramedullary plasmacytomas are highly radiosensitive and radiotherapy is therefore used as a treatment. In this study, we report on a rare case of EMP of the larynx evaluated with computed tomography and present histopathologic findings for a 74-year-old female patient.

Abstract
A solitary fibrous tumor is a rare spindle cell neoplasm originating from the mesenchyme. This type of tumor of the orbit is very uncommon and can be misdiagnosed as a hemangiopericytoma, fibrous histiocytoma, meningioma, or neurofibroma. We report an orbital solitary fibrous tumor in an 18-year-old male, with slow-growing swelling in the right orbital region. An orbital contrast-enhanced computed tomography scan showed heterogeneously enhancing right extraconal inferomedial mass, with no evidence of calcification or bone destruction. The lesion was surgically excised without complications. Based on microscopic and immunohistochemical findings, the mass was finally diagnosed as a solitary fibrous tumor. These tumors should be preoperatively differentiated from other spindle cell tumors of the orbit, and radiological imaging methods are useful in the differential diagnosis but are nonspecific. Therefore, histopathological and immunohistochemical staining features are more useful for the diagnosis of solitary fibrous tumors, especially CD34 staining.

The diagnostic value of 4D MRI at 3T for the localization of parathyroid adenomas. Eur J Radiol 2019; 112:207-213. [PMID: 30777212 DOI: 10.1016/j.ejrad.2019.01.022] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2018] [Revised: 11/03/2018] [Accepted: 01/21/2019] [Indexed: 10/27/2022]
Abstract
PURPOSE The aim of this study was to assess the feasibility of four-dimensional magnetic resonance imaging (4D MRI) at 3 T for the localization of parathyroid adenomas. MATERIALS AND METHODS Preoperative 4D MRI scans, encompassing dynamic contrast-enhanced (DCE) sequences and non-contrast enhanced (non-CE) sequences, including a T2-weighted multipoint Dixon (T2-mDixon) sequence, with in-phase, out-phase, and water-only images, were evaluated retrospectively in 41 patients with surgically proven parathyroid lesions. Two readers who were blinded to the surgical findings independently reviewed the images in two sessions (non-CE sequences alone and non-CE + DCE sequences). The MRI localization of the suspected adenoma in each session and the consensus interpretation of the MRI images, were compared with the surgical results and interobserver agreement was assessed. RESULTS By interpreting the non-CE sequences alone, reader 1 correctly localized 34 parathyroid lesions (sensitivity 81.0%, positive predictive value (PPV) 87.2%), and reader 2 correctly localized 34 parathyroid lesions (sensitivity 81.0%, PPV 91.9%). With the addition of DCE sequences, reader 1 correctly identified 35 parathyroid lesions (sensitivity 83.3%, PPV 87.5%), while reader 2 correctly identified 36 parathyroid lesions (sensitivity 85.7%, PPV 92.3%). Overall, MRI detected 38 parathyroid lesions (sensitivity 90.5%, PPV 95.0%). Interobserver agreement was slightly superior in non-CE + DCE sequences compared to non-CE sequences alone (ĸ = 0.796 vs. ĸ = 0.738). CONCLUSION 4D MRI with DCE sequencing is a reliable method for the localization of parathyroid adenomas.

Abstract
OBJECTIVES To evaluate the parenchymal elasticity of the thyroid gland with acoustic radiation force impulse imaging in pediatric patients with Hashimoto thyroiditis and to compare it with healthy volunteers. METHODS Twenty-six patients with Hashimoto thyroiditis and 26 healthy volunteers between 6 and 17 years were included. The shear wave velocity (SWV) values of both thyroid lobes in both groups were evaluated. RESULTS The age and sex characteristics of the controls and patients with Hashimoto thyroiditis were similar. The SWV of the thyroid gland in patients with Hashimoto thyroiditis (mean ± SD, 1.67 ± 0.63 m/s) was significantly higher than that in the control group (1.30 ± 0.13 m/s; P < .001). There was no significant difference between the thyroid lobes in both groups. A receiver operating characteristic curve analyses showed an optimal cutoff value of 1.41 m/s, with 73.1% sensitivity, 80.8% specificity, a 79.2 % positive predictive value, and a 75.0% negative predictive value (area under the curve, 0.806; P < .001). In patients with Hashimoto thyroiditis, there was a positive correlation between the SWV values versus anti-thyroperoxidase (Pearson r = 0.46; P = .038). There were no correlations between age, body mass index, thyroid function test results, and anti-thyroglobulin values and versus SWV values. Also, no significant differences were seen between the groups for gland size, gland vascularity, and l-thyroxine treatment. CONCLUSIONS Acoustic radiation force impulse elastography showed a significant difference in the stiffness of the thyroid gland between children with Hashimoto thyroiditis and the healthy group. Using acoustic radiation force impulse elastography immediately after a standard ultrasound evaluation may predict chronic autoimmune thyroiditis.

Abstract
PURPOSE To determine the exact anatomic location and volume of the thickest section of the greater wing of the sphenoid bone (trigone), which is removed during deep lateral orbital wall decompression. METHODS Eighteen dried skulls were used to determine the exact anatomic location and computed tomography (CT) images of 20 patients (10 male, 10 female) were used for volumetric calculations. RESULTS Mean values were 14.5 mm for the orbital rim to inferior orbital fissure distance, 23.3 mm for rim to trigone distance, 13.0 mm for width of the trigone base, 5.8 mm for trigone to orbital apex distance, and 12.3 mm for trigone height. The width of the narrowest section of the trigone was 5.2 mm. The trigone was found to have a lower segment (0.92 cc) neighboring the inferior orbital fissure, and an upper segment (0.32 cc) adjoining the thick substance of frontal bone. The narrowest part between these two segments was located just at the superior border of the lateral rectus muscle. CONCLUSIONS The authors recommend avoiding the thin rectangular portion located in the inter-fissural area adjacent to the superior orbital fissure. A high intersubject variability underscores the need for individualized preoperative analysis by imaging studies.

Abstract
OBJECTIVE The aim of this study is to determine the prevalence of jugular bulb-vestibular aqueduct dehiscence (JBVAD) in patients undergoing temporal bone multidetector computed tomography (MDCT) and assess the relationship between JBVAD and hearing loss with the findings of audiometry. METHODS About 1503 temporal bone MDCT scans were evaluated for the prevalence of JBVAD. Correlation of the imaging findings and audiometric data was performed. Patients were divided into two groups, those with and those without hearing loss, and were statistically compared. RESULTS Jugular bulb-vestibular aqueduct dehiscence was detected in 124 of the 1503 patients with a prevalence of 8.2%. MDCT images of 56 of the 124 patients were normal except for JBVAD (n = 38) and close proximity of the jugular bulb (JB) and vestibular aqueduct (VA) (n = 18). A total of 23 of 38 patients with JBVAD and 7 of 18 patients with close proximity of the JB and VA had hearing loss detected by audiometric evaluation. CONCLUSIONS The most common hearing loss was detected as sensorineural hearing loss in patients with JBVAD. Also, median air and bone conduction and air bone gap values were found statistically higher in patients with hearing loss versus those without hearing loss.

Abstract
Tracheal diverticulum (DV) is a type of paratracheal air cyst (PTAC) that is often asymptomatic and usually detected incidentally by imaging methods. Tracheal DV are divided into two subgroups: congenital and acquired. Dysphagia, odynophagia, neck pain, hoarseness, hemoptysis, choking, and recurrent episodes of hiccups and burping can also be seen in symptomatic patients. Thin-section multidetector computed tomography (MDCT) is useful for diagnosis of tracheal diverticulum. The relationship between DV and tracheal lumen can be demonstrated by axial, coronal, and sagittal reformat multiplanar images. Bronchoscopy can also be used in diagnosis for tracheal DV. However, the connection between DV and tracheal lumen can not be shown easily with bronchoscopy. Conservative treatment is the preferred treatment in asymptomatic patients. Surgical or conservative treatment can be performed for symptomatic patients, depending on patient age and physical condition.

Abstract
Ectopic cervical thymus (ECT) is a rare cause of neck mass in the pediatric age group. It is extremely uncommon in infants. Overall more than 100 cases have been reported in the literature, though fewer than 10% involved infants. Furthermore, ECT is usually unilateral and more frequently seen in men than in women. Ultrasound (US) is the preferred initial imaging modality, especially in pediatric neck masses given its wide availability, low cost and lack of radiation exposure. US can show the location, extension, and echotexture of the ECT. Magnetic resonance imaging (MRI) can be performed to verify the diagnosis and confirm communication between the ECT and the mediastinal thymus. Diffusion restriction can aid diagnosis when seen in a neck mass similar to that in the mediastinal thymus. Herein is described a case of bilateral ECT in a 2-month-old boy with associated US and MRI findings.

Abstract
BACKGROUND Selection of nodules for surgery diagnosed as Bethesda category III [atypia of undetermined significance/follicular lesion of undetermined significance (AUS/FLUS) category] is very important. We aimed at to define the predictive factors for malignancy and factors associated with triage to surgery. METHODS The records of all patients with nodules who underwent fine needle aspiration biopsy (FNAB) and classified by Bethesda reporting system as AUS/FLUS between 2011 and 2015 at our institution were reviewed. Univariate and multivariate analysis were performed to select independent factors associated with thyroid cancer and with triage to surgery. Using independent risk factors for malignancy predictive index categories were created. RESULTS Of the 485 patients who were classified as AUS/FLUS on initial FNAB, 153 underwent surgery with the associated malignancy rate of 22.8%. The malignancy rates for AUS/FLUS patients with and without repeat FNAB were 37.5% and 16.2%, respectively. Multivariate logistic regression analysis revealed that solid structure, microcalcification, hypoechogenicity, increased vascularization, and irregular margin were found to be significant and independent risk factors associated for malignancy, and solid structure, microcalcifications, increased nodule size (≥2 cm) and younger patient age (<65 years) were associated with triage to surgery. CONCLUSIONS Our findings showed that using predictive factors for malignancy in AUS/FLUS category as risk indices, an important proportion of patients (35%) who had nodules without any risk factors could be spared unnecessary surgery. We suggest that predictive indices should be considered for selection of the patients to triage to surgery.

Abstract
OBJECTIVE The aim of this study is to investigate the diagnostic accuracy of muscle-to-nodule strain ratio (MNSR) in the differentiation of benign and malignant thyroid nodules and to see if there was a difference between MNSR and parenchyma-to-nodule strain ratios (PNSR) in diagnosis. METHODS A total of 106 consecutive patients (88 women and 18 men; age range 19-79 years) with thyroid nodules were prospectively examined using ultrasound and sonoelastography before the fine-needle aspiration biopsy. The mean MNSR and PNSR were calculated for each nodule and the elasticity score was determined according to four-point scoring system. RESULTS According to the four-point scoring system, 44 of the 83 benign nodules had a score of one or two while 22 of the 23 malignant nodules had a score of three or four (p<0.001). Using ROC analysis, the best cutoff point for MNSR 1.85 and for PNSR 3.14 was calculated. The sensitivity and specificity for the MNSR were 95.6%, 92.8%, respectively; for the PNSR were 95.6%, 93.4%, respectively, when the best cutoff points were used (p<0.001). The κ value for the PNSR and MNSR methods was 0.87, which indicated an almost perfect agreement (p<0.001). CONCLUSIONS Sonoelastography has a high diagnostic accuracy in the differentiation of benign and malignant thyroid nodules. There was no significant difference between MNSR and PNSR in the differentiation of benign and malignant thyroid nodules. Therefore, we think that MNSR could safely be used in situations where PNSR could not be used.

Abstract
PURPOSE Internal jugular vein is anatomic continuation of cranial dural sinuses in the neck region. During the course of skull base the first enlarged segment of jugular vein is described as jugular bulb. The aim of this study is to evaluate the jugular bulb abnormalities and define the risk of high and dehiscent jugular bulb injury during middle ear surgery. METHODS This is a retrospective radiologic study of 1,010 patients (2,020 temporal bones) with various ear symptoms who had high resolution temporal bone computed tomography scans between 2007 and 2011. RESULTS High jugular bulb was seen in 308 (15.2 %) temporal bones. Jugular bulb dehiscence was encountered in 153 (7.5 %) temporal bones. High jugular bulb and jugular bulb dehiscence were more common in the right ears and females. Forty-one (2 %) temporal bones revealed high and dehiscent jugular bulb which can be vulnerable during middle ear surgery. High and dehiscent jugular bulb was more common in the right ears and males. Male predominance becomes more significant in the left ears. Of the 308 temporal bones with high jugular bulb, 87 (28.2 %) also had coexisting carotid canal dehiscence. CONCLUSION High and dehiscent jugular bulb is an important anatomic variation that can result in catastrophic outcomes during middle ear surgery. Our series show that 2 % of patients can be considered in the "high-risk" group. Precise assessment of the preoperative computed tomography scans by both the radiologist and the ENT surgeon is of utmost importance. Preoperative awareness will minimize morbidity and mortality.

Abstract
PURPOSE To present 3 cases with nasolacrimal canal agenesis who underwent repetitive unsuccessful probing for treatment of congenital epiphora. MATERIALS AND METHODS Three patients who had undergone topical antibiotic therapy, lacrimal sac massage and repetitive probing in Ondokuz Mayis University, Medical School, Ophthalmology Department between June 2006 and March 2007 were included in the study. Thin-section computerized tomography (CT) scan was performed in all cases since nasolacrimal duct could not be detected during repetitive probing. RESULTS Among the patients 2 were males and 1 was a female. They were within the age range 5-7. Since it was not possible to cannulate the nasolacrimal canal during probing, CT scans were performed and nasolacrimal duct agenesis was detected in 3 patients. One of the patients had additional upper punctum agenesis, who also had no right frontal sinus and left sphenoid sinus. All tomographic images revealed a rudimentary upper nasolacrimal canal ending blindly and a lower canal leading into the maxillary sinus, which was very typical for the duct agenesis. In all patients, lacrimal fossas were shallow and irregular. CONCLUSION Nasolacrimal duct agenesis should be considered in patients with congenital nasolacrimal duct obstruction and unsuccessful repetitive probing, especially if it is difficult to cannulate nasolacrimal canal during probing. Although assessing whether dacryocystorhinostomy is in favor of the patient, the lacrimal sac and fossa should be examined with imaging in details.

Abstract
The aim of this study was to determine the diagnostic value of ultrasonographic measurements in ulnar neuropathy at the elbow (UNE) and to assess the relationship between the measurements and the electrophysiological severity. The largest anteroposterior diameter (LAPD) and cross-sectional area (CSA) measurements of the ulnar nerve were noted at multiple levels along the arm, and the distal-to-proximal ratios were calculated. Almost all of the measurements and swelling ratios between patients and controls showed statistically significant differences. The largest CSA, distal/largest CSA ratio, CSA at the epicondyle, and proximal LAPD had larger areas under the curve than other measurements. The sensitivity and specificity in diagnosing UNE were 95% and 71% for the largest CSA, 83% and 85% for the distal/largest CSA ratio, 83% and 81% for the CSA at the epicondyle, and 93% and 43% for the proximal LAPD, respectively. There was a statistically significant correlation between the electrophysiological severity scale score (ESSS) and the largest CSA, the CSA at the epicondyle and 2 cm proximal to the epicondyle, and the LAPD at the level of the epicondyle (P < 0.05). None of the swelling ratios showed a significant correlation with the ESSS. The largest CSA measurement is the most valuable ultrasonographic measurement both for diagnosis and determining the severity of UNE.

Abstract
BACKGROUND The distinction between severe pulmonary embolism (PE) and right heart dysfunction is important for predicting patient mortality. PURPOSE To identify the role of computed tomographic pulmonary angiography (CTPA) in the assessment of the severity of acute PE and right ventricular dysfunction. MATERIAL AND METHODS Eighty-five patients suspected of having PE, as diagnosed by CTPA and scintigraphy, were divided into three groups: hemodynamically unstable PE (HUPE) (n = 20), hemodynamically stable PE (HSPE) (n = 33), and no PE (n = 32). For each patient, obstruction scores, including short-axis diameters of the right ventricle (RV) and left ventricle (LV), main pulmonary artery, and superior vena cava (SVC), were measured. The RV/LV short-axis ratios were calculated. The shapes of the interventricular septum and the reflux of the contrast medium into the inferior vena cava (IVC) were evaluated. The mortality due to PE within a 1-month follow-up period was recorded. RESULTS The median CTPA obstruction score (HUPE 64%, HSPE 28%, P < 0.001), median RV/LV short-axis ratio (HUPE 1.4, HSPE 1.0, P < 0.01), median RV diameter (HUPE 55 mm, HSPE 42 mm, P < 0.001), median SVC diameter (HUPE 23 mm, HSPE 19 mm, P < 0.01), interventricular septum convex toward the LV (HUPE 70%, HSPE 18%, P < 0.001), and reflux of the contrast medium into the IVC (HUPE 65%, HSPE 33%, p < 0.05) were significantly different between the HUPE and HSPE groups. With ROC analysis, the CTPA obstruction score and RV/LV short-axis ratio threshold values for the HUPE patients were calculated to be 48% (95% sensitivity, 76% specificity) and 1.1 (85% sensitivity, 76% specificity), respectively. Three patients in the HUPE group died within the first 24 hours. Logistic regression methods revealed only the RV diameter as a significant predictor of death (odds ratio 1.24; 95% CI 1.04-1.48; P = 0.01). CONCLUSION This study found that the parameters useful for distinguishing HUPE and HSPE included CTPA obstruction score, RV and SVC diameters, RV/LV short-axis ratio, interventricular septum shape, and reflux into the IVC. RV dilatation may be a significant predictor for mortality.

Abstract
OBJECTIVE The term "competitive flow" defines the flow from a partially stenosed native artery that "competes" with the flow from a graft to perfuse the distal tissues. The purpose of our study is to investigate the effects of competitive flow at different degrees of stenosis at common carotid artery, in a rabbit model by measuring both the flow volume and velocity in the venous graft. METHODS This prospective experimental study included 33 rabbits, which were divided into three groups: in Group 1, the common carotid arteries were ligated to form a total occlusion, in Group 2, the common carotid arteries were externally incompletely ligated to achieve 50% stenosis, and in Group 3, common carotid arteries were fully patent. The jugular vein was reversed and anastomosed to proximal and distal common carotid arteries using end to side anastomosis technique. Mean arterial pressure, the total flow and velocity were measured in native carotid arteries prior to surgery and in venous grafts 2 months after surgery using Doppler ultrasonography. Statistical analysis was performed using Chi-square test and Kruskal Wallis analysis of variances. RESULTS There were no differences in graft mean velocity (Group 1--16.8+/- 6.7 cm/sec, Group 2--14.1+/- 6.1 cm/sec and Group 3--12.1+/- 6.7 cm/sec), and mean flow volume (Group 1--33.9+/- 11.5 mL/min, Group 2--29.0+/- 8.3 mL/min, and Group 3--24.4+/- 12.8 mL/min) between groups after surgery (p>0.05 for both). CONCLUSION As it was the case in this rabbit model, the reduction of flow volume or velocity in lesser degrees of stenosis in the carotid artery venous bypass grafts is not significant in a statistical perspective. Although in short-term this effect did not create a difference for graft patencies between the groups, it may be important in long-term.

Abstract
Our aim was to assess the effects of initial ultrasonography (US) evaluation on the diagnosis and management of non-traumatic acute abdominal pain in the emergency department. Three hundred patients with the complaint of non-traumatic acute abdominal pain who were sent for US examination with an initial clinical impression were included in the study. Pre-US and post-US surveys were designed for the clinicians who requested US. The percentage concordance of US findings with the discharge diagnosis made by clinical follow-up, imaging modalities and surgery was determined by calculating the confidence interval. The concordance of the initial clinical impression and the US diagnosis with the discharge diagnosis were compared using the McNemar test. US could not detect any pathology in 102 (34%; 95%CI, 28.6-39.3%) of the patients. The US revealed a different diagnosis than the clinical impression in 69 (23%; 95%CI, 18.2-27.7%), and confirmed the diagnosis in 121 (40%; 95%CI, 34.4-45.5%) patients. The US changed the treatment plans in 47% (95%CI, 41.3-52.6%) of the patients. The clinicians stated US helped them "very much" or "moderately" in making a diagnosis in 83% (95%CI, 78.7-87.2%). When US results were compared with the discharge diagnosis, there was concordance in 238 (79.3%; 95%CI, 74.3-83.6%) patients but not in 62 (20.6%; 95%CI, 16-25.1%). Among 121 patients the initial clinical impression agreed with the US diagnosis and there was concordance with the discharge diagnosis in 105 (86.7%; 95%CI, 80-92.7%). The concordance of US findings with the discharge diagnosis was significantly higher than that of the initial clinical impression statistically. In the initial evaluation of the patients with acute abdominal pain, US is considerably helpful in making the correct diagnosis, and that the concordance with the discharge diagnosis is high. When whole abdominal scanning is not performed, targeted US study according to the initial clinical impression decreases the clinical benefit of US.

Abstract
BACKGROUND Myocardial bridging (MB) is a congenital anomaly in which a segment of coronary artery is surrounded by myocardium. PURPOSE To investigate the correlation between muscle thickness over the tunneled coronary artery (depth) in MB and the presence of milking effect (ME) and systolic narrowing ratio in catheter angiography (CA). MATERIAL AND METHODS The records of 36 patients who underwent a coronary computed tomography angiography (CTA) and following CA examination for suspicious ischemic coronary artery disease, between March 2005 and September 2007, were retrospectively evaluated. According to the depth of MB on CTA, patients were grouped into four groups: group 1, <1 mm; group 2, 1- <2 mm; group 3, 2- <4 mm; group 4, >or=4 mm. The presence of milking effect, systolic narrowing ratio, and atherosclerotic stenosis at CA were recorded. CTA and CA results were then compared to evaluate the correlation. RESULTS In total, ME was found in 15 arteries at CA (42%). There was no ME in group 1; it was present in 11% of group 2, 67% of group 3, and 100% of group 4. Starting from group 3, the percentage of likelihood of seeing the milking effect was 77%, and the percentage of systolic narrowing was between 30 and 70%. There was a significant correlation between depth of MB and systolic narrowing (P<0.01), while no significant correlation between length of MB and systolic narrowing was found (P=0.32). In seven of the 36 patients (group 1, 0; group 2, 1; group 3, 3; group 4, 3), clinical findings were related to pure MB. CONCLUSION The depth of MB is positively related to coronary narrowing and clinical ischemic findings.

Abstract
OBJECTIVE Noninvasive diagnostic methods do not supply sufficient data for patients with left bundle branch block (LBBB) accompanied with coronary artery diseases (CAD). Therefore, generally coronary angiography is required for these patients. Our aim was to evaluate the diagnostic value of multislice spiral computed tomographic (MSCT) coronary angiography to detect CAD in patients with LBBB. METHODS Sixty one patients (31 males, 30 females, mean age: 56+/-13 years) with LBBB who have determined stenosis higher than 50% in quantitative coronary angiography were included in the cross-sectional study. The MSCT coronary angiography was applied to the patients with a 16-detector MSCT scanner that has an electrocardiographic synchronization unit. Each coronary artery was evaluated segmentally in the images acquired from MSCT coronary angiographies and any detected stenosis higher than 50% was recorded. RESULTS The data of 793 coronary artery segments achieved from MSCT coronary angiographies of 61 patients (13 segments for each patient) were compared with the results of conventional coronary angiographies of the same patients. When all the segments evaluated were included in this comparison, the diagnostic accuracy, sensitivity, specificity, positive and negative predictive values of MSCT coronary angiography to detect stenosis higher than 50% were 91%, 67%, 97%, 85% and 92%, respectively. Also, it was observed that, MSCT coronary angiography has 80% sensitivity and 90% specificity to detect, at least, one segment coronary artery stenosis. CONCLUSION The MSCT coronary angiography can be utilized as a noninvasive diagnostic method for patients with LBBB, in order to evaluate coronary artery disease.

Abstract
PURPOSE The aims of this study were to determine the value of chest radiography in diagnosing lung parenchymal injury in patients with thoracic trauma, and to evaluate the frequency of lung parenchymal injury by using thoracic computed tomography (CT). MATERIALS AND METHODS Between January 2005 and June 2006, we retrospectively evaluated the anteroposterior chest radiographs and thoracic CTs of 60 patients that presented to our emergency department and were hospitalized due to multi-organ trauma. RESULTS Chest radiography revealed parenchymal injury in 32 of the patients, while thoracic CT confirmed parenchymal injury in only 27 of these 32 patients. Chest radiographs did not reveal any parenchymal injury in 28 of the patients, whereas thoracic CT detected parenchymal injury in 12 of these 28 patients. Thoracic CT results were accepted as the gold standard in the evaluation of patients with chest trauma and showed that the sensitivity, specificity, positive predictive value, and negative predictive value of chest radiography in determining parenchymal injury were 69%, 76%, 84%, and 57%, respectively. In addition, thoracic CT revealed that 65% of the patients with blunt thoracic trauma suffered parenchymal injury. CONCLUSION The sensitivity of anteroposterior chest radiography in identifying lung parenchymal injury was low, with a high false negative rate; therefore, we think that early evaluation with thoracic CT is extremely helpful in the diagnosis and treatment of patients with thoracic trauma, adding to the cooperative work that exists between radiologists and emergency physicians.

Abstract
Primary vascular leiomyosarcoma is a rare tumor, which arises mainly from the inferior vena cava. Clinical signs are non-specific. Systemic metastasis occurs in the late stage. Imaging with color Doppler ultrasonography, contrast-enhanced computed tomography, or magnetic resonance imaging can significantly contribute to the diagnosis. We present a case of leiomyosarcoma of the inferior vena cava that extended into the right renal vein and the right iliac vein, as it is a rare case and emphasize the significance of the imaging methods in its diagnosis.
