Abstract
OBJECTIVE The aim of this study was to describe different lesions and features associated with developmental venous anomalies (DVAs). METHODS The records and magnetic resonance imaging (MRI) images of 1,722 patients who underwent cranial MRI between 2010 and 2017 were retrospectively reviewed. It was found that 124 (7.2%) patients had DVAs, and 48 of these patients (38.7%) had additional anomalies accompanying DVAs. Of the patients with DVAs, 25 were female and 23 were male, with a mean age of 39.3 years (range, 3-77 years). MRI was performed in all the patients. RESULTS In addition to DVAs, cavernomas were present in 30 patients (62.5%), haematomas in 7 (14.5%), gliosis in 6 (12.5%), demyelinating plaques in 4 (8.3%) and a glioblastoma in 1 (2.2%). The mean diameter of the DVAs was 1.1mm and the mean diameter of the lesions was 17.4mm. The susceptibility weighted imaging (SWI) sequence was also applied to 12 patients with cavernomas. The relevant sequence in all of these patients contributed to the diagnosis. CONCLUSION Our study shows that DVAs can accompany a wide spectrum of lesions, especially cavernomas. Although their pathophysiology has not yet been clearly established, these lesions may have a common aetiology.

Abstract
BACKGROUND In this study, we aimed to image pulmonary venous return anomalies and associated cardiovascular and pulmonary abnormalities by high-pitch low-dose computed tomography (CT) in children. MATERIALS AND METHODS Forty-one patients with total or partial anomalous pulmonary venous return anomalous between May 2012 and June 2019 were retrospectively reviewed. The anomalies were determined using high-pitch low-dose CT. The patients' mean age was 3 years (6 months to 15 years), and 24 of them were female. RESULTS There were 10 patients with total pulmonary venous return anomalies (TPVRA) and 31 patients with partial pulmonary venous return anomalies (PPVRA). Six (60%) patients with TPVRA had the supracardiac type, 2 (20%) had the cardiac type, and 2 (20%) had the mixed type. All patients with TPVRA had a large atrial septal defect (ASD), 1 patient also had patent ductus arteriosus, and 1 patient had right cardiac hypertrophy. Forty cases of PPVRA were found in 31 patients. Twenty-seven (67%) of them were right-sided, and 13 were left-sided (33%). Twenty (65%) patients also had an additional cardiovascular anomaly (ASD in 12 patients, persistent superior vena cava in 4 patients, patent ductus arteriosus in 3 patients, and aortic coarctation in 2 patients). Of the 27 patients with right-sided PPVRA, it drained into the superior vena cava in 19 patients, the right atrium in 5 patients, and the inferior vena cava in 3 patients. In left-sided cases, the anomalous pulmonary vein drained into the left innominate vein in 9 patients, and in 4 patients, there were accessory pulmonary veins that drained into the left innominate vein. Many of the patients had additional lung anomalies, including pneumonic infiltration (n = 12), atelectasis (n = 8), and lobar emphysema (n = 5), and some of these findings coexisted. CONCLUSIONS Anomalous pulmonary venous drains and associated cardiac and extra-cardiac anomalies can be detected reliably and quickly with high-pitch low-dose CT without sedation in paediatric patients.

Abstract
The cerebral perivascular spaces are interstitial fluid-filled anatomic structures surrounding the perforating arteries. They appear as small, round or curvilinear structures on magnetic resonance (MR) imaging. Occasionally, these structures may become very large and cause mass effect. In this case, they may imitate malignant processes and are referred to as tumefactive perivascular spaces. In this study, we present a case of tumefactive perivascular space demonstrated with post-contrast time-of-flight (TOF) MR angiography. To our knowledge, there have been no previous clear demonstrations of the perforating artery in tumefactive perivascular space with contrast-enhanced TOF MR angiography. The purpose of this study was to describe advanced imaging findings in this unusual condition.

Abstract
The Abernethy malformation is characterised by congenital extrahepatic portosystemic shunts and is divided into two groups according to the type of anastomosis. In type 1, all portal venous blood is discharged into the inferior vena cava and there is no intrahepatic portal vein. In type 2, the portal vein is partially discharged to the inferior vena cava via side-by-side anastomoses. Imaging has an important role in the diagnosis and follow-up of this malformation. Magnetic resonance imaging should be preferred to demonstrate both vessel anatomy and associated anomalies. The aim of this study was to present a 17-year-old male patient and to discuss the imaging findings of Abernethy malformation.

Abstract
PURPOSE To determine the value of diffusion-weighted magnetic resonance imaging (DW-MRI) in discriminating between hepatic alveolar echinococcosis (AE) and hepatocellular carcinoma and intrahepatic cholangiocarcinoma. METHODS We included 49 patients (27 men, 22 women; mean age: 52.02±9.76 [SD] years; range: 25-72years) with 57 histopathologically confirmed hepatic AE lesions. Fifty patients (18 men, 32 women; mean age: 58.93±8.42 [SD] years; range: 42-71years) with 61 histopathologically confirmed hepatocellular carcinoma and 50 patients (24 men, 26 women; mean age: 50.11±7.70 [SD] years; range: 38-69years) with 54 histopathologically confirmed intrahepatic cholangiocarcinoma lesions were used as control groups. All patients had MRI examination of the liver that included conventional MRI sequences and DW-MRI using b values of 50, 400 and 800s/mm2. Two radiologists evaluated conventional MRI and DW-MRI images and calculated ADC values of hepatic lesions. RESULTS The mean ADC value of solid components of hepatic AE lesions was 1.34±0.41×10-3 mm2/s (range: 0.9-1.59×10-3 mm2/s) and was significantly higher than that of the solid components of hepatocellular carcinoma lesions (mean ADC value, 0.99±0.29×10-3 mm2/s; range: 0.7-1.15×10-3 mm2/s) and of intrahepatic cholangiocarcinoma lesions (mean ADC value, 1.05±0.22×10-3 mm2/s; range: 0.86-1.18×10-3 mm2/s) (P<0.001). CONCLUSION In general ADC values can help discriminate between AE and hepatocellular carcinoma and intrahepatic cholangiocarcinoma. However, the use of ADC values cannot help differentiating Type 4 AE from hepatocellular carcinoma or intrahepatic cholangiocarcinoma.

Abstract
OBJECTIVE We have compared conventional Color Doppler (CD) and Power Doppler (PD) techniques, which are used for evaluating the testicular blood flow in small children, and the Superb Microvascular Imaging (SMI), which is a new technique. We have also investigated their contributions to testicular evaluations. PATIENTS AND METHODS We evaluated blood flow in testicles using a grading system with CD, PD and SMI techniques. We determined the average duration of the three techniques. RESULTS There was a statistically significant difference between the SMI and CD techniques for all patients (p < 0.001, p = 0.001). When we compared the PD and SMI, either as much or more vascular information was obtained (p = 0.106). There was a statistically significant difference between the application durations of the tests (p < 0.05). CONCLUSIONS Superb Microvascular Imaging yields more detailed vascular information in blood flow in testicles in small children, than either CD or PD. Furthermore, this technique decreases the duration of the examination at a significant level. Superb Microvascular Imaging may represent an alternative method that can be used safely for evaluating blood flow in the testicles of small children. Additional studies may increase the reliability of SMI.

Abstract
BACKGROUND Vascular complications are a primary diagnostic consideration in liver transplant recipients, with an overall incidence of 9%. Cross-sectional imaging techniques provide information regarding vascular structure and luminal patency but can not quantitatively assess hepatocyte damage in the liver graft parenchyma. Perfusion computerized tomography (CT) is a recently developed method that allows for quantitative evaluation of hemodynamic changes in tissue. Our objective was to evaluate the clinical utility of perfusion CT in assessing vascular complications during living-donor liver transplantation (LDLT). METHODS The 33 recipients were divided into 3 groups according to Doppler ultrasonographic findings: hepatic arterial complication group, portal venous complication group, and hepatic venous complication group. Blood volume (BV), blood flow (BF), arterial liver perfusion (ALP), portal venous perfusion (PVP), and hepatic perfusion index (HPI) were calculated for the affected vascular territory regions. RESULTS Compared with normal liver parenchyma, BV, BF, ALP, and HPI were significantly lower in the hepatic arterial complication group. Although PVP and BV were significantly lower, ALP, HPI, and BF were higher in the affected vascular territory region than in normal liver parenchyma for the portal venous complication group. In the hepatic venous complication group, PVP was significantly higher and BF, ALP, and HPI significantly lower in the affected vascular territory regions than in normal liver parenchyma. CONCLUSIONS Perfusion CT imaging is a noninvasive technique that enables the quantitative evaluation of vascular complications in the graft parenchyma after LDLT and permits a quantitative evaluation of the treatment response.

Abstract
Supernumerary testis or polyorchidism is a rare congenital anomaly with about 200 reported cases in the literature. It may be associated with cryptorchidism, testicular torsion and neoplasms. Ultrasonography and magnetic resonance imaging are effective noninvasive methods of accurately detecting polyorchidism. In most cases, ultrasonography is diagnostic and magnetic resonance imaging plays confirmatory role by providing additional information if complicated with neoplasia. We report a case of 16-year-old man with right supernumerary testis associated with adenomatous hyperplasia of the rete testis, its sonographic and magnetic resonance imaging findings and management.

Abstract
Partial anomalous pulmonary venous return (PAPVR) is a congenital anomaly that involves drainage of one to three pulmonary veins directly into the right heart or systemic venous system, creating a partial left-to-right shunt. This drainage is associated with cardiac abnormalities such as mitral stenosis and pulmonary stenosis, patent ductus arteriosus, and atrial septal defects. We report a case of PAPVR associated with vascular anomalies of the aorta by multidetector computed tomography in an adult female patient.

Abstract
A 19-year-old female patient was admitted to our hospital with dyspnea, chest pain, and shortness of breath. A chest radiograph showed mild cardiomegaly. Echocardiography revealed an extra chamber in the heart. To evaluate this abnormality, ECG-gated 16-detector-row computed tomography angiography was performed. Multidetector computed tomography (MDCT), showing cor triatriatum with total anomalous pulmonary venous connections (TAPVC), clearly revealed cardiac and vascular anatomy. ECG-gated cardiac MDCT is a useful tool for detection and characterisation of cor triatriatum and related anomalies.

Abstract
OBJECTIVE The purpose of this study was to compare the sensitivity for detecting foreign bodies among conventional plain radiography, CT and ultrasonography in in vitro models. METHODS Seven different materials were selected as foreign bodies with dimensions of approximately 1 x 1 x 0.1 cm. These materials were metal, glass, wood, stone, acrylic, graphite and Bakelite. These foreign bodies were placed into a sheep's head between the corpus mandible and muscle, in the tongue and in the maxillary sinus. Conventional plain radiography, CT and ultrasonography imaging methods were compared to investigate their sensitivity for detecting these foreign bodies. RESULTS Metal, glass and stone can be detected with all the visualization techniques used in the study in all of the zones. In contrast to this, foreign bodies with low radiopacity, which could be detected in air with CT, became less visible or almost invisible in muscle tissue and between bone and muscle tissue. The performance of ultrasonography for visualizing foreign bodies with low radiopacity is relatively better than CT. CONCLUSIONS Ultrasonography detects and localizes superficial foreign bodies with low radiopacity in the tissues of the body more effectively than CT and conventional plain radiography. However, CT is a more effective technique for visualization of foreign bodies in air than ultrasound and conventional plain radiography.

Abstract
PURPOSE The authors present the findings of contrast-enhanced electrocardiogram (ECG)-gated cardiac computed tomography (CT) in 18 patients with probably spontaneous closure of muscular ventricular septal defect (VSD). MATERIALS AND METHODS The study included 2,725 consecutive patients referred to our hospitals for multidetector computed tomography (MDCT) coronary angiography. The patients were between the ages of 5 and 78 [mean+/-standard deviation (SD) 59+/-13.86] years, and 1,816 (66.6%) were male. Evaluating the images for coronary artery pathologies revealed pouches or sacs in the central muscular location of the septa of some patients. RESULTS All patient records were retrospectively reviewed, and 18 patients were found to have pouches or sacs in the interventricular septum location likely to be spontaneous closure of muscular VSD (0.66% prevalence). MDCT findings of these 18 patients correlated with their echocardiographic findings. Of the patients with muscular VSD, 13 were male and five were female. These 18 patients were initially referred due to indications such as chest pain (n=11), risk-factor assessment (n=3), coronary artery anomaly (n=1), suspected aberrant right subclavian artery due to dysphagia (n=1) and coronary artery bypass graft (n=2). CONCLUSIONS Our study shows that the incidence of spontaneous closure of muscular VSD with central septum location is probably higher than expected. Thus, some patients initially diagnosed with ventricular diverticula with an apical and marginal septum location may actually have spontaneously closed muscular VSD. This finding may affect previously reported rates of both ventricular diverticula and spontaneous closure of muscular VSD.

Abstract
PURPOSE To evaluate the appearance, type, frequency, and clinical importance of retroaortic left renal vein (RLRV) in patients examined with multidetector computed tomography (MDCT) angiography. MATERIALS AND METHODS A total of 1856 patients who underwent CT with urological symptoms (hematuria, flank and abdominal pain, left gonadal vein varicocele) (n = 889) or with symptoms other than urological ones (n = 967) were prospectively evaluated for the presence of RLRV. CT was performed with 110 ml of iodinated contrast material through the antecubital vein at a rate of 3.5 ml/s. Late arterial and early venous phase volumetric data sets were acquired at 30 and 65 s, respectively, from the start of the intravenous injection of contrast medium. In addition to axial images, multiplanar reconstructions (MPR), maximum-intensity projection (MIP), and three-dimensional volume-rendering (3D VR) images were used to assess left renal vein anomalies. Left renal vein anomalies were classified into four types according to their appearance: I) RLRV joining the inferior vena cava (IVC) in the orthotopic position; II) RLRV joining the IVC at level L4-L5; III) circumaortic or collar left renal vein; IV) RLRV joining the left common iliac vein. RESULTS RLRV was detected in 68 (3.6%) of the 1856 patients, with 26, 22, 17, and three of types I, II, III, and IV, respectively. Forty-four of the 68 patients with RLRV (65%) were in the group with urological symptoms, while 24 patients (35%) were in the group without urological symptoms. Compression of the RLRV was found in 16 patients in the urological symptoms group, while compression was detected in only three patients in the other group. This difference was statistically significant (P<0.05). The most common urological symptom was hematuria. The frequency of urological symptoms was higher in groups II and IV compared to the other groups. CONCLUSION MDCT angiography with axial, MPR, MIP, and 3D VR images is effective in the detection of vascular renal anomalies such as RLRV. Diagnosing RLRV and differentiating it from other pathologic conditions causing hematuria is important in order to avoid complications during retroperitoneal surgery or interventional procedures.

Abstract
Traumatic rupture of the diaphragm usually results from blunt or penetrating injuries, or iatrogenic causes. Most cases are initially overlooked in the acute phase because they present with variable clinical and radiological signs. An overlooked diaphragmatic injury presents as a hernia many years later with potentially serious complications, therefore selection of the most appropriate radiological technique and accurate diagnosis of traumatic diaphragmatic hernias (DH) on the first admission is important. Although the diagnosis of diaphragmatic injuries is problematic, various investigations may be used for diagnosis. We describe the imaging findings of 19 traumatic DH cases with various imaging techniques. The patients were acute trauma cases or cases with prior trauma or thoraco-abdominal surgery with clinical suspicion of DH. An evaluation of the imaging techniques used in the diagnosis of DH is presented.

Abstract
A 23-year-old woman was transferred to our department with loss of consciousness 6 h after undergoing rod placement for thoracolumbar scoliosis. Both computed tomography and magnetic resonance imaging of the brain revealed diffuse pneumocephalus and infra- and supratentorial hemorrhages. The pedicular screw tracts were analyzed with computed tomography and misplacement of a screw was noticed. It was thought that inadvertent dural injury had occurred at the time of insertion. The patient was re-operated and the dural tear was repaired. To our knowledge, this is the first description of these uncommon complications in one patient after spine surgery.

Abstract
The purpose of this study was to determine the amount of atrophy occurring in the cerebrum of patients with multiple sclerosis compared with controls, and to show the relationship between clinical status and distribution of atrophy. MR images were obtained on 12 relapsing-remitting (RR) and 11 secondary progressive (SP) multiple sclerosis patients and 24 control subjects (all patients and controls were female). The Cavalieri method by modern design stereology was used to measure the cerebral volume. It was found that volumes for RR and SP with multiple sclerosis and control subjects were 757242 mm3, 716867 mm3 and 912499 mm3 respectively. Mean estimates of volume loss in RR and SP were 20.5% and 27.2% respectively compared to controls for the cerebrum. In addition the volume difference between RR and SP was 5.6%. There were statistically significant differences between both RR (P<0.05) and SP (P<0.05) compared with control subjects but no differences between RR and SP volumes. MRI-estimated cerebrum volumes may be help to evaluate patients' clinical status and provide a simple index to assess the efficiency of therapy.

Abstract
PURPOSE To determine brainstem volumes, number of plaques, and surface areas in the occipital lobes of patients with relapsing remitting multiple sclerosis (RRMS) and secondary progressive multiple sclerosis (SPMS), and to investigate whether there is any correlation between brainstem volume and the number/surface areas of plaque in the occipital lobes. MATERIAL AND METHODS Magnetic resonance imaging was obtained on 14 relapsing-remitting (RR) and 13 secondary progressive (SP) MS patients and 26 female control subjects. The Cavalieri method was used by modern design stereology to measure brainstem volume. The point-counting grid was used to evaluate sclerotic plaque surface areas in the occipital lobe. The number of plaques in the imaging section was calculated. RESULTS Brainstem volumes for RR and SP with multiple sclerosis and control subjects were 3647 mm3, 3515 mm3, and 4517 mm3, respectively. Mean number of plaques in the right-left occipital lobe was found to be 2.7-3.4 in RR-MS and 5.2-2.8 in SP-MS. Mean plaque surface area in the right-left occipital lobe was determined to be 58.52-88.24 mm2 in RR MS and 124.3-64.82 mm2 in SP MS. Brainstem volumes were significantly reduced in both groups of patients with MS compared to controls (P < 0.01). CONCLUSION Magnetic-resonance-estimated volume and surface area values in multiple sclerosis may facilitate our understanding of the clinical situation of patients and provide a simple index for evaluating therapeutic efficiency.

Abstract
PURPOSE To investigate the angulation, length, and structural variations of the styloid process (SP) by multidetector computed tomography (MDCT). MATERIAL AND METHODS MDCT scans were performed in 283 cases (127 M and 156 F, age range 18-77 years). The length of the SP and its angulation on the transverse and sagittal planes were measured. Structural variations of the SP were observed by means of three-dimensional (3D) and multiplanar reconstruction (MPR) images. RESULTS The length of the bony SP on both sides varied from 0 to 62 mm (mean 26.8 +/- 10.0 mm). Angulation ranged between 55 degrees and 90.5 degrees (7 2.7 +/- 6.6) in the transversal plane and between 76 degrees and 110 degrees (93.5 +/- 6.9) in the sagittal plane. Morphologically, the SP showed a considerable amount of variation. A solitary SP was present in 168 individuals (59.4%). In 9 individuals (3.1%), the SP was duplicated (4 unilateral and 5 bilateral). Sixty-one persons (21.6%) showed an incomplete ossified SP (42 unilateral and 19 bilateral), whereas in 7 individuals (2.5%) a bony SP was absent entirely (7 unilateral). In 38 individuals (13.4%), the stylohyoid ligament was ossified (16 entirely, 22 partial). In all individuals, 3D and MPR images showed the SP in its entire length. CONCLUSION MDCT with 3D CT and MPR of SP may show further detailed information related to SP. Not only the length of the SP, but also its 3D orientation, should be in focus in anatomical and clinical studies.

Abstract
Hepatocellular carcinoma (HCC) has a tendency for fatal spontaneous rupture leading to massive haemorrhage. A 64-year-old man presented with sudden, severe epigastric pain for 6 h. Systolic blood pressure was 80/50 mmHg, and pulse rate was 100/min. The patient's history did not reveal any operation or disease up to date. Contrast enhancement-axial computed tomography (CT) scan showed a tumoral lesion with a necrotic centre measuring 6 x 5 cm within 6th segment of the liver and a fluid collection (haemoperitoneum) at the periphery of the liver. At exploratory laparotomy, the liver was found to be cirrhotic, and an actively bleeding tumour confirmed in 6th segment of the liver. The tumour was resected. Post-operative recovery was unremarkable, and the patient was discharged on the 14th post-operative day. Ruptured HCC should be included in the differential diagnosis of non-traumatic intra-abdominal haemorrhage.

Abstract
SUMMARY. The purpose of the present study is to estimate tumor volumes of 10 patients with esophageal carcinoma on serial CT images that are obtained before and after chemoradiotherapy using a stereological method. In this study, tumor volume was measured using the Cavalieri method of modern design stereology with a combination of three separate stages. Firstly, detailed systematic series of axial CT images of 1-cm thickness were obtained throughout the whole tumor area of each subject and to magnify them all CT images were projected on a screen by overhead projector and then were marked by manually tracing the outline of areas with tumor on serial CT images that are projected onto the screen. Secondly these images were drawn on paper. Finally the images on paper were evaluated with a point-counting method. It was shown in a pilot study analyzed that 100 test points counted on about 6--8 serial slices through for esophagus wall, lumen and wall + lumen are sufficient to secure coefficient of error (CE) on the estimates of volumes as in this study. It was found that tumor volumes before and after radiotherapy for esophagus wall, lumen and wall + lumen was 10.34 cm(3), 1.15 cm(3) and 11.75 cm(3) before and 5.93 cm(3), 1.43 cm(3) and 7.65 cm(3) after radiotherapy, respectively. When only esophagus wall and lumen volumes or wall + lumen volumes before and after radiotherapy were statistically compared, the difference between either esophagus wall (P<0.01) and lumen (P<0.01) volumes or total volumes (P<.1) were significant. It is concluded that CT estimated tumor volumes may be helpful in both evaluating the clinical situation of patients and providing a simple index to assess the efficiency of therapy, prediction of tumor regression rate and minimizing the risk of chemoradiotherapy damage.

Abstract
We describe a 9-year-old child with a history of trichoptysis caused by intrapulmonary teratoma and we present the CT and MRI findings of the teratoma. A heterogeneous mass containing cystic and solid elements was detected on both CT and MRI scans. Histopathological examination confirmed the diagnosis of teratoma. Teratomas arising from lung parenchyma, as in this case, are extremely rare in childhood. In the thoracic region, the most common localization of teratomas is the anterior mediastinal compartment. We also discuss the CT and MRI findings and the differential diagnosis of teratomas.

Abstract
OBJECTIVE The objective of the present study was to investigate the possible correlation between the common carotid artery (CCA) intima-media thickness (IMT) and the infarct side. METHOD The CCA IMTs in patients with atherosclerotic non-lacunar stroke were measured. RESULTS The mean age of the patients was 64.3 +/- 10.7 years (range 40-83 years) and 42 of 100 patients were male. The infarcts were at the left side in 53 patients and at the right side in 47 patients. The mean CCA IMT was 1.02 +/- 0.18 mm at the infarct side and 0.87 +/- 0.17 mm at the contralateral side. The difference between them was statistically significant (P < 0.01). Although the mean age of the patients with a left-sided infarct was greater than that of the patients with a right-sided infarct, the difference was not statistically significant. CONCLUSION Our results suggest that CCA IMT may be used in prediction of possible infarct side, and in the prediction of potential risk of stroke by evaluating the IMT of both CCAs separately.
