Strategies for the follow-up of focal ablation of prostate cancer combine serial post-procedural PSA, multiparametric MRI examinations, and biopsy, although the optimal follow-up regimen remains controversial. In this study, we propose a co-registration and 3D visualization method for comparing prostate tumors on pre-treatment T2W-MRI and ablation cavities on post-treatment DCE-MRI as a measure of proper treatment coverage. Our preliminary findings suggest that this co-registration method may be used to help assess treatment efficacy.
