(A) Histotripsy-generated cavitation is seen as a hyperechoic zone on B-mode ultrasound. (B) ‘M’ shaped histotripsy lesion shows as a hypoechoic zone on B-mode ultrasound image. (C) Histotripsy ablation zone is seen as a hypointense (non-enhancing) region on this T1-weighted contrast-enhanced MR image.
