Transperineal focal laser ablation (TPLA) has the potential to obtain oncological control, while sparing nearby tissue to preserve continence and erectile function with a low toxicity profile. However, registration and prediction of the ablation zone is essential for TPLA to become a clinal standard of care treatment. In this study we investigated the capability of MRI and CEUS to image the treated volume. We show that the treatment effects of TPLA can reliably be visualized using these techniques and that the results are in good agreement with histopathology. These results are essential first steps towards improved planning and performance of TPLA.
