ACCURACY OF ACR-TIRADS IN ROUTINE USG REPORTING

Abstract

Nodules in the thyroid gland are very common. As per the American Thyroid Association (ATA), thyroid nodules are dened as “discrete lesions within the thyroid gland, radiologically distinct from the surrounding thyroid parenchyma”. The incidence of thyroid cancer has been increasing worldwide in the last few decades (1). Papillary thyroid carcinoma attributes more than other histological subtypes of thyroid carcinoma (2,3). . The malignant nature of the nodule cannot be determined by physical examination and blood tests alone; hence specialized tests such as thyroid ultrasonography and ne needle biopsy are often required (4). To establish the accuracy of ACR-TIRADSObjective: classication system in the diagnosis of thyroid nodules in routine USG reporting and also to evaluate their Doppler characteristics. To conclude the study, the proper stratication of the thyroid nodules onResults & Conclusion: ultrasound-based TIRADS system helps us to determine the probability of a particular nodule being malignant with a certain level of condence and appropriate measures for management of the nodule can be initiated, thus avoiding unnecessary FNA procedures. The addition of Color Doppler further strengthens the probability of a nodule being malignant and thus prompt action can be initiated by the referring clinician/surgeon.
