A novel approach to assessing changes in prostate stiffness with age using virtual touch tissue quantification.

Objectives: Virtual touch tissue quantification is a promising new implementation of the acoustic radiation force impulse ultrasound technique. The purposes of this study were to describe the normal shear wave velocity values of the prostate by virtual touch tissue quantification and to examine the clinical usefulness of this procedure in evaluation of age-related shear wave velocity changes in the prostate.

Methods: One hundred twenty healthy volunteers were involved in this study.
