Abstract
To explore the clinical value of virtual touch tissue imaging VTI for breast tumors, and compared with pathology. 128 patients with breast tumors underwent conventional ultrasound and VTI. The characteristics of conventional ultrasound, VTI score and pathological results of all cases were retrospectively analyzed. On VTI: score of 1 to 3 were found in 86.7% benign lesions. Scores 4 to 5 were found in 82.4% malignant lesions. There were statistically difference in the scores of VTI between benign and malignant tumors (P < 0.01). With the scores of VTI 1 to 3 judged to benign and 4 to 5 judged to malignant, the sensitivity and specificity of VTI were 82.4% and 86.7%, respectively. VTI had positive significance in differentiating benign and malignant tumors. This new method had a high specificity and positive predictive value.
