Current Release

Access PI-RADS

To expedite the transfer of high-quality MRI from laboratories to patients to help improve early diagnosis of clinically significant prostate cancer and reduce unnecessary biopsies and treatment for benign and subclinical diseases. PI-RADS 2.0 and 2.1 are joint developments between the ACR, ESUR and Admetech Foundation.

Using PI-RADS v2.1 for Prostate MRIEducation Activity

Primer for Using PI-RADS v2.1 for Prostate MRI

This educational activity was developed to provide radiologists with basic information about prostate MRI acquisition, interpretation and reporting.

The activity is divided into seven sections that can be reviewed linearly or nonlinearly to facilitate self-paced learning. Illustrative examples are used to describe normal prostate anatomy, the PI-RADS assessment categories, prostate cancer staging and caveats for imaging interpretation.

The basic elements of a structured prostate MRI report and the technical standards for image acquisition described in PI-RADS v2.1 are also reviewed. At the end of each section, important concepts are reviewed in knowledge checks. Links to supporting documents and other resources are provided at the end of the activity.

Learning Objectives

  1. Outline the principles of PI-RADS v2.1 and the scoring system during the interpretation of mpMRI of the prostate.
  2. Describe caveats for the interpretation of prostate cancer mimickers.
  3. Demonstrate how to report imaging findings using the standardized format.
  4. Cite ways to optimize prostate imaging protocols using the mpMRI principles to achieve the best diagnostic performance.

In order to successfully complete the activity participants must complete an activity evaluation and claim credit commensurate with their participation in the activity.
