Objective  To explore the value of virtual touch tissue quantification(VTQ) of acoustic radiation force impulse (ARFI) in the differential diagnosis between benign and malignant thyroid nodules. Methods  The ultrasound (US), elastography imaging(EI), and VTQ of ARFI were performed to determine the characteristics and features of 63 thyroid nodules. The pathological diagnosis was the gold standard. According to the receiver operating characteristic curve (ROC) of US, EI, and VTQ, the critical points and diagnostic values of US, EI, and VTQ in diag-nosis of malignant thyroid nodules were achieved. Results  Of the 63 nodules, 45 were benign and 18 were malignant. The area under curves of US, EI, and shear wave velocity(SWV) were 0.837(95% CI:0.712-0.962), 0.863(95% CI:0.751-0.974), and 0.900 (95% CI:0.810-0.990) respectively, and all the 3 kinds of technique had diagnostic value(P=0.001), but there were no significant difference among the 3 kinds of technique on the area under curve(P > 0.05). According to the receiver operating characteristic(ROC) curve, the critical point of US in distinguishing benign nodules with malignant nodules was 3 conventional ultrasonography, which displayed a sensitivity of 83.3%, a specificity of 86.7%, and a accuracy of 85.7%. The critical point of EI grades in distinguishing benign nodules with malignant nodules was gradeⅣ, which displayed a sensitivity of 94.1%, a specificity of 82.6%, and a accuracy of 87.3%. The critical value of SWV in distinguishing benign nodules with malignant nodules was 3.39 m/s, which displayed a sensiti-vity of 88.9%, a specificity of 91.1%, and a accuracy of 90.5%. Conclusion  US, EI, and VTQ techniques all have diagnostic values in the differential diagnosis between benign and malignant thyroid nodules, and we should make combination with all of the 3 kinds of technique when performing differential diagnosis.
