title: Prostate imaging reporting and data system (PI-RADS): reflections on early experience with a standardized interpretation scheme for multiparametric prostate MRI.
abstract: OBJECTIVE
  In this article, we provide our perspective on current multiinstitutional efforts to improve standardization of interpretation and reporting of multiparametric prostate MRI, emphasizing their strengths and limitations based on our experiences, and provide several suggestions for guiding continued initiatives for standardizing multiparametric prostate MRI reporting.
  
  
  CONCLUSIONS
  Significant steps are being taken to facilitate the adoption of prostate MRI by urologists and other physicians in the community. Ultimately, however, prospective multicenter validation studies assessing the various aspects of a diagnostic test will be required.
