Diagnostic value of multiparametric MRI in detecting residual or recurrent prostate cancer after high-intensity focused ultrasound.

Albeit with low sensitivity, high suspicion on post-HIFU MRI may be clinically important because of its high specificity, especially when considering the possibility of sampling error in biopsies. Patients with a high number of cancer-positive cores at diagnosis should avoid HIFU as they have an increased risk of recurrence.
