Abstract

Background: This was a prospective study to evaluate thyroid nodules and differentiate benign from malignant nodules using ACR-TIRADS classification.

Materials and Methods: In our prospective study of 30 patients with thyroid nodules were evaluated using ACR-TIRADS categories. The risk of malignancy for each category were calculated and correlated with FNAC/Histopathology.

Results: We have studied 30 patients with thyroid nodules, Out of 30 lesions, 22 were found to be benign and 8 lesions were malignant. The risk of malignancy for ACR-TIRADS1, TIRADS2 and TIRADS 3 were 0%, TIRADS 4 and TIRADS 5 lesions had 28.6%, and 85.7% risk of malignancy respectively. In our study papillary carcinoma was the most common malignant pathology and colloid nodule was the most common benign entity.

Conclusions: ACR TI-RADS is more accurate in differentiating malignant thyroid nodules from benign nodules, and more reliable in recommending thyroid nodules for FNA. By using ACR-TIRADS, unnecessary FNAC can be avoided.

Keyword: Thyroid nodules, ACR-TIRADS (American College of Radiology Thyroid Imaging Reporting and Data System), FNAC (fine needle aspiration cytology).
