Figure 7.
73-year-old male with a history of Gleason 7 prostate cancer treated with focal laser ablation therapy with rising prostate-specific antigen and findings suspicious for recurrence in the right anterior mid-peripheral zone. (a) Axial T2-weighted and (b) dynamic contrast enhanced images demonstrate a region of T2 hypointense signal in the right anterior mid-peripheral zone consistent with posttreatment changes (arrow), but within this region there is a small focus of rapid contrast wash-in and wash out (arrow), suspicious for recurrent tumor.
