Multiparametric MR imaging of the Prostate: Pitfalls in Interpretation.

Multiparametric MR imaging is widely embraced for the diagnosis, staging, and surveillance of prostate cancer. However, normal anatomic structures and many benign entities have overlapping imaging features with prostate cancer. Although some of these entities require biopsy and histopathologic diagnosis, some have characteristic imaging features that are suggestive of their diagnosis. Knowledge of these pitfalls is important in establishing a correct diagnosis and avoiding unnecessary biopsies, as these entities are encountered routinely in clinical practice.
