Acoustic Radiation Force Impulse Elastography for Efficacy Evaluation after Hepatocellular Carcinoma Radiofrequency Ablation: A Comparative Study with Contrast-Enhanced Ultrasound
Figure 3
Virtual touch tissue quantification (VTQ) before (a) and after (b) RFA. Before RFA the shear wave velocity of this tumor is 1.32 m/s, while after RFA the shear wave velocity in the ablated area shows x.xx m/s (i.e. out of the range of the measurable values).
