Six patients with recurrent PCa were successfully treated with transperineal MR-guided focal cryoablation in a closed-bore 1.5 tesla MR scanner. In all patients a hyper intense ice ball rim was clearly visible on T1-weighted images and iceball growth and thus critical temperature zone were carefully monitored. No major complications were recorded. After 3 months PSA level decreased and follow-up MRI showed no cancer. Initial results are promising and more patients have to be included.
