Points are assigned based on 5 ultrasound features and the sum de- termines the ACR TI-RADS classification of the nodule [13]. The 2015 ATA guidelines classified the TNs into five patterns according to the combination of US fea- tures and each pattern had an estimated risk of malig- ...
Points are assigned based on 5 ultrasound features and the sum determines the ACR TI-RADS classification of the nodule [13]. The 2015 ATA guidelines classified the TNs into five patterns according to the combination of US features and each pattern had an estimated risk of malignancy (Table 1)...

Objectives: The thyroid nodule is one of the most common endocrine system diseases. Risk classification models based on ultrasonic features have been created by multiple professional societies, including the American College of Radiology (ACR), which published the Thyroid Imaging Reporting and Data ...
(ACR) recommended the Thyroid Imaging Reporting and Data System (TI‐RADS) as a classification system to standardize thyroid ultrasound reports and to predict the probability of malignancy in thyroid nodules using a scoring system (TR1‐TR5) based on multiple ultrasound characteristics and nodule ...
TIRADS classification showed that there was 1 (1.0%) nodule in TR2 class, 20 (20.0%) nodules in TR3 class, 72 (72.0%) nodules in TR4 class and 7 (7.0%) nodules in TR5 class. Comparing the results of FNA with TIRADS classification showed that there were no malignant nodules in TR2...
Next, we combined qualitative and quantitative SMI to upgrade and downgrade the C-TIRADS classification. If a C-TR4B nodule had VIsum >12.2 or intra-nodular vascularity, the original C-TIRADS was upgraded to C-TR4C. If a C-TR4C or C-TR4B nodule manifested VIsum ≤12.2 and no intra...
