The objectives of this session is to review protocols for prostate MRI in the post-treatment setting, describe the appearance of whole-gland treatment effects and recognize findings suspicious for residual or recurrent disease. Early detection of recurrence is important for treatment planning and prognosis. Detection in the post treatment cases can be challenging. Advances in mpMRI helps to differentiate recurrence from mimics. Familiarity with imaging appearances of recurrence and mimics helps to make a correct and timely diagnosis.
