The TIRADS is a scoring system used for the selection of nodules for FNA and classification of the risk of malignancy based on ultrasound characteristics. The BETHESDA is a standard reporting system used for the classification of FNA results based on six criteria with risks for malignancy. The objective of this study was to evaluate the relationship between TIRADS and BSRTC classifications in patients undergoing thyroid biopsy. A total of 350 consecutive patients were retrospectively evaluated using TIRADS and BETHESDA reporting systems for determining preoperative diagnosis of thyroid nodules. Patients’ demographics, size, echogenicity and contour status of the nodules, TIRADS and BETHESDA scores were recorded and analyzed. Data obtained in this study were expressed as mean, standard deviation, frequency and percentage descriptive statistics. The mean age of the patients was 49.03 ± 17.58 years. The mean nodule size was measured as 20.56 ± 10.47 mm. TIRADS TR3 category was found in 165 (47.14%), TR4 in 154 (44%) and TR5 in 31 (8.86%) patients, while BETHESDA II category was found in 288 (82.28%), BETHESDA III category in 1 (0.29%), BETHESDA IV category in 19 (5.43%), BETHESDA V in 37 (10.57%) and BETHESDA VI in 5 (1.43%) patients. There was a general concordance between BETHESDA and TRIADS categories. The most significant concordance was found between BETHESDA IV and TR4 categories (84.21%). Combined use of TRIADS and BETHESDA can be efficiently used to provide the most accurate results for making preoperative diagnosis of thyroid nodules and to determine the risk of malignancy.
