Evaluation of Virtual Touch Tissue Imaging Quantification (VTIQ - 2D-SWE) in the Assessment of BI-RADS® 3 and 4 Lesions: Can Patient Selection for Biopsy be Improved? - A Confirmatory Multi-Center-Study
In Brief
A clinical study evaluating Ultrasound- Virtual Touch Tissue Imaging Quantification for Breast Neoplasms. Completed, enrolled 1,304 participants across 11 sites in 6 countries.
Detailed Summary
The primary aim of this study is to evaluate if VTIQ in addition to BI-RADS® categorization can improve the diagnostic accuracy with respect to detection of malignancies, in particular for BI-RADS® categories 3 and 4a. The idea of the study is to restage all patients in categories 3 and 4a according to a predefined VTIQ cut-off value of ≥ 3.5 m/s (37 kPa).

Timeline
Interventions
Siemens Medical Solutions USA, Inc. (Mountain View, CA) has implemented Virtual Touch Tissue Imaging Quantification (VTIQ) technology on a commercially available general purpose US imaging system (trade name: Acuson S2000 or S3000). This system has received clearance under Food and Drug Administration (FDA) 510(k) number K072786 (S3000) and K130881 (VTIQ). The technology uses a set of tailored US pulses (Acoustic Radiation Force Impulse, ARFI) to induce shear waves in breast tissue due to tissue displacement. A set of standard B-mode pulses detect the perpendicular shear waves. The displacement signals can be processed using algorithms on a Virtual Touch IQ-equipped system in order to calculate the shear wave velocity.
