MRI evaluation of cavitation induced by laser prostatectomy.
Magnetic resonance images obtained by endorectal surface coils have shown histopathological changes in the prostate. In patients who underwent laser prostatectomy, MR imaging demonstrated how deeply the laser energy penetrated and how different changes were induced by the coagulation and vaporization techniques. Cavitation effects were quantitatively analyzed, and the processes of reepithelization after sloughing of necrotic tissues were observed in gadolinium-enhanced T1-weighted images.
