Abstract
Objective To evaluate the value of shear wave elastography(SWE)combined with ultrasonic MicroPure ima-ging in differential diagnosis of category 3 or 4 nodules in thyroid imaging report and data system(TI-RADS). Methods 127 cases of patients with TI-RADS category 3 or 4 thyroid nodules were screened using conventional two-dimensional ultrasonography through assessing the border,aspect ratio and internal echo of the thyroid nodules,156 nodules in total. Every nodule underwent ultrasonic MicroPure imaging and SWE scanning sequentially to acquire Young modulus. The value of MicroPure imaging,SWE or the combi-nation of the two in the diagnosis of TI-RADS category 3 or 4 was compared,with all nodules verified by postoperative pathology or fine needle aspiration(FNA). Results ①The average Young modulus of benign and malignant thyroid nodules was(25. 18 ± 14. 64)kPa and(64. 58 ± 24. 69)kPa,respectively,with statistically significant between-group difference(P＜0. 05).②Areas un-der the ROC curve of ultrasonic MicroPure imaging and conventional two-dimensional ultrasonography in the detection of microcal-cification in the nodules were 0. 870 and 0. 577,respectively,the difference being statistically significant(p＜0. 05).③The sensi-tivity and accuracy of ultrasonic MicroPure imaging combined with SWE ( 92. 31% and 88. 46%) in differential diagnosis of TI-RADS category 3 or 4 nodules were both higher than those of conventional two-dimensional ultrasonography alone,the difference being statistically significant(P＜0 05). Conclusion The combination of SWE and MicroPure imaging on the basis of convention-al two-dimensional ultrasonography can improve the diagnostic accuracy of TI-RADS category 3 or 4 nodules,providing diagnostic basis for clinical treatment.关键词
