Fig. 2 — Viable tissue after ablation. Images of a 66-year-old patient with PCa in the peripheral posterolateral zone on the left (Gleason 3 + 3) and in the peripheral right apical zone (Gleason 3 + 4) undergoing TULSA whole-gland ablation. The tumor was proven via biopsy and could not be detected not demarked in the MR-images. Almost the entire segmented tissue reached the threshold for the calculated cell death in the dose map (green and yellow voxels). A small rim of enhancing tissue is visible in the left peripheral zone after treatment. Nevertheless, no residual viable prostatic tissue is detected in the T2-weighted follow-up examination after 6 months, and no recurrence has occurred to this day (19 months after treatment)
