Abstract：Objective To explore the value of superb microvascular imaging(SMI)combined with thyroid imaging report and data system(TI-RADS)in differential diagnosis of benign and malignant thyroid nodules.Methods A total of 110 patients with thyroid nodules treated from January 2020 to January 2023 were selected,and underwent routine ultrasound and SMI examination,and TI-RADS classification was performed according to routine ultrasound.Using surgical and patholog-ical results as the gold standard,the diagnostic efficiency of SMI and TI-RADS alone and in combination for benign and malig-nant thyroid nodules was compared,and blood flow classification of nodules was performed by SMI.Results Among 110 ca-ses,58 were malignant thyroid nodules(thyroid cancer)and 52 were benign.Using pathological results as the gold standard,the sensitivity,specificity and accuracy of SMI in the diagnosis of malignant thyroid nodules were 91.38%,80.77%and 86.36%,respectively,those of TI-RADS were75.86%,76.92%and 76.36%,respectively,and those of SMI combined with TI-RADS were 94.83%,88.46%and 91.82%,respectively.The sensitivity and accuracy of combination of SMI,SMI and TI-RADS in the diagnosis of malignant thyroid nodules were higher than those of TI-RADS(P＜0.05).In SMI mode,the proportion of malignant thyroid nodules in blood flow grade 2-3 was higher than that of benign nodules(P＜0.01).Conclu-sion SMI combined with TI-RADS can effectively improve the diagnostic efficiency of malignant thyroid nodules,and SMI blood flow grading is conductive to the qualitative diagnosis of thyroid nodules.
