Abstract :

Aim : To characterize the thyroid nodules according to grey scale sonographic using TIRADS scoring system with its TIRADS score and correlate the results with the histopathological examination findings wherever possible. Materials and methods : This prospective study was done on the study group comprising of 100 patients , referred for ultrasound thyroid. Ultrasound evaluation was done based on TIRADS lexicon features such as the internal composition, echogenicity, margins, presence and type of calcifications, and the shape of all these lesions. Observations and analysis : Out of the five suspicious sonological features, irregular margins showed the highest positive predictive value for malignancy followed by taller than wide shape , microcalcifications . Completely cystic composition, hyper echogenicity, and macrocalcifications were features with 100% PPV and 100% sensitivity for benignity in our study. Among these features, irregular margins were the most sensitive for malignancy followed by taller than wide shape, micro calcification, marked hypoechogenicity, and solid composition in that order. We found that as the number of suspicious TIRADS features increased, the risk of malignancy also increased.
