Evaluation of penile erection rigidity in healthy men using virtual touch tissue quantification

Evaluation of penile erection rigidity in healthy men using virtual touch tissue quantification

BACKGROUND The aim of the study was to describe the shear wave velocity (SWV) values of the penis by virtual touch tissue quantification (VTTQ) and to examine the clinical usefulness of this procedure in evaluation of the rigidity changes in penile erection. PATIENTS AND METHODS.: VTTQ was performed in 37 healthy volunteers. In the course of erection, SWV values of glans penis, corpus penis an...

preliminary study on the kidney elasticity quantification in patients with chronic kidney disease using virtual touch tissue quantification

conclusion vttq can sensitively detect the elasticity changes in patients with ckd, and it can effectively predict renal insufficiency. this technology provides a valuable tool for the assessment of ckd. patients and methods sixty-five patients with ckd and seventy healthy participants were included in this study. a total of 270 kidneys were examined by vttq. the kidney elasticity was expressed...

Penile Erection

Hemodynamic Aspects Penile erection and detumescence are primari ly controlled by hemodynamic events. Increased arterial inflow appears to be of primary importance; the contribution of increased venous resistance to the production of penile erection remains controversial. Furthermore, our understanding of precise anatomic details ( including “shunts”) and the neural control of vascular events i...

[Clinical value of virtual touch tissue quantification and PGA index in evaluation of alcoholic liver fibrosis].

OBJECTIVE To explore the clinical value of virtual touch tissue quantification (VTQ) technique and the PGA index [prothrombin time (P), γ-glutamyl transpeptadase (GG) and apolipoprotein A1 (ApoAl)] in evaluating the degree of liver fibrosis in alcoholic patients.
 METHODS A total of 64 patients with long-term alcohol history were enrolled for this study. The liver ultrasonography elasticity w...
