Abstract
To identify the accuracy of ultrasound in determining malignant nodules and compare the Thyroid Imaging Reporting and Data System (TIRADS) of classifying thyroid nodules on ultrasound with the findings on fine-needle aspiration cytology (FNAC) reported using the Bethesda System of classification.
Material and Method: We conducted prospective, correlational study which enrolled 130 patients of all age group who had been referred to radiology department for assessment of thyroid nodule. The study was performed using 7-12 Hz linear frequency probe of E-saote ultrasound machine. High frequency thyroid ultrasound were performed in all cases and TIRADS score was noted which was later correlated with Bethesda score on FNAC.
Results: Study was done for a period of 1.5 year in patients who were sent to radiology department for assessment of thyroid nodule. The age group most commonly represented in study is 41-60 years. Benign as well as malignant nodules were more frequent in female than in male. We observed that TIRADS classification was significantly associated with BETHESDA classification and risk of the malignancy of a thyroid palpable nodule increases along with the TIRADS category.
