Recent Developments in Multiparametric Prostate MR Imaging

Multiparametric magnetic resonance imaging (mpMRI) of the prostate has become a mature and accepted technology in the evaluation of the patient with suspected prostate cancer (PCa). This review focuses on key recent developments in the area of mpMRI, specifically: reporting systems used by radiologists when interpreting mpMRI, advances in technical aspects of diffusion-weighted imaging (DWI), and innovations in MRI-ultrasound (MRI-US) fusion-guided prostate biopsies. These topics were selected given that reporting systems are critical when communicating findings on mpMRI of the prostate to referring clinicians, advanced techniques in DWI have improved the detection and characterization of PCa, and MRI-US fusion biopsies now enable more accurate targeting of suspicious lesions at biopsy, including lesions that are difficult to visualize using standard B-mode ultrasound imaging. Radiologists interpreting prostate MRI today are likely to incorporate aspects of all three of these topics into their current practice.
