OBJECTIVE. In this article, we describe 10 diagnostic challenges that may confound the interpretation of multiparametric prostate MRI for tumor, grouped into three categories on the basis of our experience: normal anatomic structures that may be misinterpreted as suspicious lesions if their normal appearance is not recognized, benign processes that may mimic tumor, and technical issues relating to acquisition and interpretation of diffusion-weighted imaging that may decrease sensitivity for tumor. Strategies for addressing these challenges are suggested. CONCLUSION. It is important that the radiologist involved in the interpretation of prostate MRI be aware of these pitfalls that will be encountered during routine clinical practice. This awareness can contribute to improved diagnostic performance in MRI interpretation.
