RecruitingPRISM Study: Prostate Recurrence Detection Using Imaging With PSMA PET/MRI Post-high Intensity Focused UltrasoundThe purpose of this study is to compare the sensitivity of PSMA PET/MRI and standard MRI in detecting focal therapy failure in the prostate one year after High-Intensity Focused Ultrasound (HIFU) treatment. Specifically, the study aims to evaluate whether PSMA PET/MRI offers a higher sensitivity than MRI alone for identifying recurrence or failure in patients undergoing focal therapy.
