ObjectiveTo explore the diagnostic value of sonography in thyroid imaging reporting and data system (TI-RADS) for thyroid nodules. MethodsA total of 292 patients (423 nodules) underwent thyroid examination with high frequency ultrasound. The results were retrospectively compared with histopathological diagnosis and TI-RADS lexicon. ResultsThe category 1-5 of 423 thyroid nodules were evaluated by using TI-RADS, and it’s frequency of being malignancy rate was 0(0/129), 6.3%(11/176), 33.3%(10/30), 86.8%(46/53), and 100% (35/35), respectively. The sensitivity, specificity, accuracy, positive predictive value, and negative predictive value for benign thyroid nodule of ultrasound in TI-RADS was 96.3%(309/321), 83.3%(85/102), 93.1%(394/423), 94.8%(309/326), and 87.6%(85/97), respectively. Positive likelihood ratio, negative likelihood ratio, and Youden’ index was 5.77, 0.04, and 79.6%, respectively. The benign and malignancy nodule of TI-RADS category were statistically difference in shape, margin, echogenicity, echotexture, composition, and calcification inside the nodule (P lt;0.001). ConclusionsTI-RADS lexicon has an important guiding value for clinical diagnosis and treatment in ultrasound examination of thyroid nodule.
