[PI-RADS 2.1 and structured reporting of magnetic resonance imaging of the prostate].

CLINICAL/METHODOLOGICAL ISSUE: The detection of clinically significant prostate cancers while simultaneously avoiding over-diagnosing tumors with low malignant potential is a challenge in clinical practice.

STANDARD RADIOLOGICAL METHODS

Multiparametric prostate magnetic resonance imaging (MRI) in accordance with the Prostate Imaging Reporting and Data System (PI-RADS) guidelines is accepted as standard-of-care with both urologists and radiologists.

METHODOLOGICAL INNOVATIONS

The PI-RADS guidelines have been updated to version 2.1, including revised technical recommendations and changes to the scoring of lesions.

PERFORMANCE

The PI-RADS guidelines have had great impact on the standardization of multiparametric prostate MRI and offer templates for structured reporting. This simplifies communication with the referring physician.

ACHIEVEMENTS

The new version 2.1 of the guidelines represents an evolutionary improvement of the widely accepted version 2.0. Several aspects of reporting have been revised-however, some pre-known limitations persist, which will require further refinement in the future.
