Multiparametric MR of the prostate provides an extremely accurate diagnosis and offers an excellent negative predictive value for cancers which biopsies struggle to detect. Combined with biopsies they consolidate both positive and negative biopsy results and allow patients to be offered more appropriate treatments (active monitoring, radical treatment in full knowledge of the topography of the lesions involved, or local treatment, etc.). The investigation does not require advanced equipment and can be carried out in any MR centre although it needs to follow a technical protocol described in the European guidelines (ESUR 2012). Interpretation should be standardized to facilitate communication of clear and consistent information between practitioners.
