[PI-RADS classification: structured reporting for MRI of the prostate]

Area of Science:

• Radiology
• Oncology
• Medical Imaging

Context:

• Prostate cancer detection relies heavily on accurate interpretation of multiparametric MRI (mMRI).
• Existing guidelines require further refinement for consistent clinical application.
• Effective communication of mMRI findings to urologists is crucial for timely diagnosis and treatment.

Purpose:

• To enhance the European Society of Urogenital Radiology (ESUR) guidelines for standardized interpretation of prostate mMRI.
• To develop a graphic reporting scheme for improved communication of mMRI findings.
• To establish consensus on technical implementation and scoring for prostate mMRI.

Summary:

• The study details the consensus-driven refinement of the Prostate Imaging Reporting and Data System (PI-RADS) for mMRI of the prostate.
• It specifies criteria for grading findings using T2-weighted MRI, diffusion-weighted imaging, dynamic contrast-enhanced MRI, and MR spectroscopy.
• A PI-RADS score of 4 or higher indicates suspected prostate cancer, with specific point thresholds for 3 or 4 techniques.

Impact:

• Standardized reporting according to ESUR guidelines enhances quality assurance in prostate mMRI.
• Improved communication through a graphic scheme facilitates better understanding between radiologists and urologists.
• This work supports more accurate and consistent diagnosis of prostate cancer.
