Thyroid gland is affected by various pathologies ranging from nodules to diffuse thyroiditis.Ultrasound is a widely accepted imaging modality for the initial assessment of thyroid nodules.TIRADS classification is a simple and reliable imaging modality to differentiate benign lesions from the malignant lesions. TIRADS can prevent unnecessary FNACs in a significant group of benign thyroid lesions. The sonographic patterns proposed by TIRADS have high sensitivity and NPV for the diagnosis of thyroid carcinoma. This classification is very much feasible for clinical application and has an excellent negative predictive value allowing the selection of patients to FNAC.
