The clinical feasibility and time efficiency of an integrated workflow for MR-guided transrectal laser treatment and real-time treatment monitoring were tested. Furthermore, temperature stability at 3T in prostate cancer patients using a fast gradient echo (GRE) echo planar imaging (EPI) sequence was evaluated.
