Abstract
OBJECTIVES The aim of this study is to evaluate (i) the reasons for requesting ultrasonography (USG) in a dentistry faculty and (ii) the scanning regions, the type of probe used, and the use of Doppler USG. METHODS USG request forms of patients who applied to our radiology clinic for USG were analyzed retrospectively. According to the clinical information of the patients in the request forms, the reasons for requesting USG were divided into four groups: soft tissue swelling, soft tissue calcification, lymph node, and other examinations. Data were statistically compared between sex (female and male) and age groups (≤40-years-old and ˃40-years-old). RESULTS The USG request forms of 50 patients were obtained. The mean patient age was 45.06±14.50 years. Twenty-six patients were female (52%), while twenty-four patients were male (48%). Soft tissue swelling, soft tissue calcification, lymph node, and other examinations were noted as the reasons for requesting USG in 42%, 26%, 18%, and 14% of the patients, respectively. The most scanned regions were the submandibular (56%), parotid (16%), and cheek (10%) regions. Extraoral probe was used more frequently than intraoral probe (78% vs. 22%). Doppler USG was used in most patients (98%). A statistically significant difference was found between age groups and calcification examination (p<0.05). CONCLUSION The reasons for requesting USG were mostly soft tissue swelling, soft tissue calcification, and lymph node examinations. The most commonly scanned region and used type of probe were the submandibular region and extraoral probe, respectively. Doppler USG was used in most patients.

Abstract
OBJECTIVES To determine the contribution of a modified definition of markedly hypoechoic in the differential diagnosis of thyroid nodules. METHODS A total of 1031 thyroid nodules were included in this retrospective multicenter study. All of the nodules were examined with US before surgery. The US features of the nodules were evaluated, in particular, the classical markedly hypoechoic and modified markedly hypoechoic (decreased or similar echogenicity relative to the adjacent strap muscles). The sensitivity, specificity, and AUC of classical/modified markedly hypoechoic and the corresponding ACR-TIRADS, EU-TIRADS, and C-TIRADS categories were calculated and compared. The inter- and intraobserver variability in the evaluation of the main US features of the nodules was assessed. RESULTS There were 264 malignant nodules and 767 benign nodules. Compared with classical markedly hypoechoic as a diagnostic criterion for malignancy, using modified markedly hypoechoic as the criterion resulted in a significant increase in sensitivity (28.03% vs. 63.26%) and AUC (0.598 vs. 0.741), despite a significant decrease in specificity (91.53% vs. 84.88%) (p < 0.001 for all). Compared to the AUC of the C-TIRADS with the classical markedly hypoechoic, the AUC of the C-TIRADS with the modified markedly hypoechoic increased from 0.878 to 0.888 (p = 0.01); however, the AUCs of the ACR-TIRADS and EU-TIRADS did not change significantly (p > 0.05 for both). There was substantial interobserver agreement (κ = 0.624) and perfect intraobserver agreement (κ = 0.828) for the modified markedly hypoechoic. CONCLUSION The modified definition of markedly hypoechoic resulted in a significantly improved diagnostic efficacy in determining malignant thyroid nodules and may improve the diagnostic performance of the C-TIRADS. CLINICAL RELEVANCE STATEMENT Our study found that, compared with the original definition, modified markedly hypoechoic significantly improved the diagnostic performance in differentiating malignant from benign thyroid nodules and the predictive efficacy of the risk stratification systems. KEY POINTS • Compared with the classical markedly hypoechoic as a diagnostic criterion for malignancy, the modified markedly hypoechoic resulted in a significant increase in sensitivity and AUC. • The C-TIRADS with the modified markedly hypoechoic achieved higher AUC and specificity than that with the classical markedly hypoechoic (p = 0.01 and < 0.001, respectively).

Abstract
Objective: To investigate the value of modified thyroid imaging reporting and data system (TI-RADS) in the sonographic diagnosis of medullary thyroid carcinoma (MTC), and to evaluate the sonographic differences among MTC, papillary thyroid carcinoma (PTC) and benign nodules in order to improve the ultrasound diagnostic accuracy of MTC. Methods: 646 cases of thyroid lesions confirmed by pathology in our hospital were divided into the MTC group (64 cases), PTC group (414 cases) and benign group (168 cases). The ultrasonographic characteristics of these groups were retrospectively analyzed. All of the 646 cases were classified by modified TI-RADS grading criteria. The diagnostic accuracy of MTC and ultrasonic manifestations of MTC, PTC and benign nodular were assessed. Results: The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of modified TI-RADS for MTC were 87.5%, 89.9%, 72.6%, 88.8%, and 67.2%, respectively. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of modified TI-RADS for PTC were 96.1%, 59.5%, 85.4%, 86.2% and 85.6%. The intraclass correlation coefficient (ICC) of three different physicians for thyroid nodules was 0.983 by the modified TI-RADS. MTC were mostly located in middle and upper parts of the thyroid (85.9%, 55/64), hypoechoic or extremely hypoechoic (89.1%, 57/64), with relatively smooth margin (35.9%, 23/64), aspect ratio<1 (53.1%, 34/64), abundant blood flow (31.2%, 20/64), and high lymph node metastasis rate (51.6%, 33/64). These differences were statistically significant when compared to PTC (P<0.05). Conclusions: Repeatability of modified TI-RADS for MTC was high, and is slightly lower than that for PTC. MTC had specific features: mostly located in middle and upper parts of the thyroid, hypoechoic or extremely hypoechoic, relatively smooth margin, aspect ratio<1, abundant blood flow and high lymph node metastasis rate.

Iran J Pediatr 2012; 22:57-62. [PMID: 23056860] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [What about the content of this article?

Abstract
OBJECTIVE Urinary tract infection (UTI) is one of the most common causes of febrile pediatric diseases. Also, vesicoureteral reflux (VUR) is a significant risk factor for UTI. Voiding cystourethrography (VCUG) is the method of choice for evaluation of VUR. This study was done to predict VUR by DMSA scan (technetium 99 m-labeled dimercaptosuccinic acid) and ultrasonography (US). METHODS In a prospective study, all children with first time acute pyelonephritis were selected and evaluated by DMSA scan and US. Then VCUG was done with negative urine culture. All children with final diagnosis of obstructive congenital anomaly were excluded. The sensitivity, specifity, positive predictive values, negative predictive values, Confidence Interval of DMSA scan and US were calculated for prediction or exclusion of VUR. FINDINGS Among 100 children with UTI diagnosis, VUR was detected in 39 children and 63 (31.5%) kidneys. DMSA scan was abnormal in 103 (51.5%) units, 45 units had VUR (PPV=44%), 79 units with normal DMSA scan had no VUR (NPV=81%). Of kidney units that were abnormal by DMSA or US, 51 units had VUR. PPV and NPV were 44% and 56%, respectively. CONCLUSION DMSA scan alone or with US cannot predict VUR (especially low grade VUR). But according to NPV, it seems that absence of VUR can be predicted. So, more studies are needed to determine the usefulness of DMSA scan and US instead of VCUG for detection of VUR.
