Ultrasound based cavitation can non-invasively fractionate tissue (histotripsy) down to sub-organelle granularity. It is unknown how bio-effects may alter in vivo histotripsy lesions. Here, we use T1 and T2 weighted MRI of harvested prostates to characterize the in vivo histotripsy lesion into three zones: a liquefied focal zone, a margin of partially disrupted tissue, and a hemorrhage zone of negligible damage.
