Objective:To investigate the application value of virtual touch tissue imaging(VTI)in the differentiation of benign and malignant TI-RADS4 solid thyroid nodules.Methods:From October 2020 to October 2021,105 thyroid nodules in 92 patients admitted to the Department of Surgery in our hospital were diagnosed as TI-RADS4 by conventional ultrasonography(CUS).Elasticity test:VTI were per-formed,the VTI elastic map were obtained.VTI area ratio(AR)was found to identify the best cut-off points for the identification of benign and malignant TI-RADS4 solid thyroid nodules.Using pathological diagnosis as the gold standard,the sensitivity,specificity and accuracy of CUS and VTI techniques in di-agnosing TI-RADS4 thyroid nodules were analyzed.Results:AR=1.28 was used as the best cut-off point for the diagnosis of the four types of thyroid malignant nodules with TI-RADS.The sensitivity,specificity and accuracy were 81.7％,92.1％and 86.3％.Conclusion:CUS combined with VTI technology can signifi-cantly improve the accuracy of diagnosing TI-RADS4 thyroid nodules.
