A Non-invasive Modality: The US Virtual Touch Tissue Quantification (VTTQ) for Evaluation of Breast Cancer

Technical evaluation of Virtual Touch™ tissue quantification and elastography in benign and malignant breast tumors

The aim of this study was to investigate the diagnostic value of the Virtual Touch™ tissue quantification (VTQ) and elastosonography technologies in benign and malignant breast tumors. Routine preoperative ultrasound, elastosonography and VTQ examinations were performed on 86 patients with breast lesions. The elastosonography score and VTQ speed grouping of each lesion were measured and compare...

Evaluation of Virtual Touch Tissue Imaging Quantification, a New Shear Wave Velocity Imaging Method, for Breast Lesion Assessment by Ultrasound

OBJECTIVES To evaluate virtual touch tissue imaging quantification (VTIQ) as a new elastography method concerning its intra- and interexaminer reliability and its ability to differentiate benign from malignant breast lesions in comparison to and in combination with ultrasound (US) B-mode breast imaging reporting and data system (BI-RADS) assessment. MATERIALS AND METHODS US and VTIQ were perf...

Diagnostic Value of Virtual Touch Tissue Quantification for Breast Lesions with Different Size

PURPOSE To evaluate diagnostic value of the virtual touch tissue quantification (VTTQ) for breast lesions with different sizes. MATERIALS AND METHODS Patients with 206 breast lesions were categorized into three groups according to lesion size (<10 mm, 10-20 mm, and >20 mm). Breast lesions were examined by conventional ultrasound and VTTQ, and shear wave velocity (SWV) of each lesion and adjac...

Virtual Touch tissue quantification cannot assess breast cancer lesions except for ductal carcinomas in situ and small invasive cancers: a retrospective study

BACKGROUND Virtual Touch tissue quantification (VTTQ) is a promising new technology that quantitatively determines the stiffness of tissue. However, the clinical impact of this device on the assessment of breast cancer is unclear. METHODS This study aimed to review the ultrasound records of patients with breast lesions where VTTQ was used to assess 123 normal breast tissues, 18 benign tumors,...
