Comparison of Virtual Touch Tissue Imaging Quantification and Spiral CT in the Application of Benign and Malignant Thyroid Nodules

Objective To analyze the application of virtual touch tissue imaging(VTI)and virtual touch tissue quantification(VTQ)and spiral CT in the application of benign and malignant thyroid nodules.Methods From January 2017 to March 2019,200 patients confirmed by operation and pathology of our thyroid surgery department were enrolled as subjects.All patients underwent routine thyroid ultrasonogra phy after admission.The internal tra nsverse shear wave velocity(SWV)and the effective SWV measurement area of the lesion were measured under VTI mode,and the maximum SWV,minimum SWV,median SWV,and average SWV were obtained in the effective measurement area.Based on the pathological diagnosis of patients,the accuracy,specificity,and sensitivity of spiral CT in the diagnosis of benign and malignant thyroid nodules were calculated.The values of VTI,VTQ,and spiral CT in the diagnosis of benign and malignant thyroid nodules were compared.Results The positive rate of TI-RADs2 was 0%,the positive rate of TI-RADs3 was 2.95%,the positive rate of TI-RADs4 a was2.95%,the positive rate of TI-RADs4 b was 20.59%,and the positive rate of TI-RADs4 c was 58.82%,and the positive rate of TI-RADs5 was 1.50%.Spiral CT scan results showed 114 benign thyroid nodules,86 malignant nodules,pathological histology showed 132 benign thyroid nodules,68 malignant nodules;specificity 86.8%,sensitivity 79.6%,accuracy 34.0%.The maximum SWV,minimum SWV,median SWV,and average SWV of malignant nodules we re significantly higher than those of benign nodules(P<0.05).The maximum area under the ROC curve(AUC)was 0.807,minimum AUC 0.815,median AUC 0.811,and average AUC 0.866 for SWV value in the thyroid,and the average diagnostic power of SWV in the nodules was optimal,with a sensitivity of 94.1%,specificity 85.7%and the accuracy 82.6.Conlusion VTI and VTQ and spiral CT have a good diagnostic value for the differential diagnosis of benign and malignant thyroid nodules,in which the average value of SWV is better.
