OBJECTIVE Ultrasound (US) features of solidity, hypoechogenicity or marked hypoechogenicity, microlobulated or irregular margins, microcalcifications, and taller-than-wide shape are suspicious characteristics for thyroid nodules. An US based Thyroid Imaging Reporting and Data System (TI-RADS) is classified based on the number of aforesaid features. TI-RADS category 3 included nodules without an...

INTRODUCTION Objective of our study was to determine the agreement between version 1 (v1) and v2 of the Prostate Imaging Reporting and Data System (PI-RADS) for evaluation of multiparametric prostate MRI (mpMRI) and to compare their diagnostic accuracy, their inter-observer agreement and practicability. MATERIAL AND METHODS mpMRI including T2-weighted imaging, diffusion-weighted imaging (DWI)...

results the interobserver agreement for sonographic descriptors changed between fair and substantial. the highest agreement was detected for mass orientation (κ=0.66). the lowest agreement was found in the margin (κ=0.33). the interobserver agreement for bi-rads final category was found as fair (κ=0.35). the intraobserver agreement for sonographic descriptors changed between substantial and alm...

PURPOSE Assess the performance of breast MRI to diagnose breast cancer in BI-RADS 4 microcalcifications detected by mammography. MATERIALS AND METHODS This retrospective, IRB-approved study included 248 consecutive contrast-enhanced breast MRI (1.5T, protocol in accordance with EUSOBI recommendations) performed to further diagnose BI-RADS 4 microcalcifications detected at mammography during a...

results the frequency of bi-rads category 3 lesions detected on screening ultrasound was 18% (90/500). of these patients, one was eventually proven to have malignancy with malignancy rate of 1.1%. this detected malignancy was early breast cancer with no lymph node metastasis. conclusions although the frequency of ultrasound bi-rads category 3 lesions is considerably high (18 %), the malignancy ...

Background. Standardised Prostate Imaging Reporting and Data System (PI-RADS) guidelines for the assessment of prostate alterations were designed for the assessment of prostate pathology. Published by the ESUR in 2012, PI-RADS v1 was based on the total score of different MRI sequences with subsequent calculation. PI-RADS v2 was published by the American College of Radiology in 2015 and featured...

OBJECTIVE To correlate the Thyroid Imaging Reporting and Data System (TI-RADS) and the Bethesda system in reporting cytopathology in 1,000 thyroid nodules. METHODS A retrospective study conducted from November 2011 to February 2014 that evaluated 1,000 thyroid nodules of 906 patients who underwent ultrasound exam and fine needle aspiration. RESULTS A significant association was found betwee...

BACKGROUND/AIM Not only that ultrasound makes the difference between cystic and solid changes in breast tissue, as it was the case at the beginning of its use, but it also makes the differential diagnosis in terms of benign-malignant. The aim of this study was to assess the role of sonography in the diagnosis of palpable breast masses according to the American College of Radiology Ultrasonograp...
