What is Multiparametric Prostate MRI (PI-RADS)?

Multiparametric prostate MRI (mpMRI) is an advanced MR protocol that combines anatomical (T2-weighted), functional (diffusion-weighted imaging-DWI), and perfusion (dynamic contrast-enhanced-DCE) sequences.

Lesions are scored from 1 to 5 with the PI-RADS (Prostate Imaging Reporting and Data System) v2.1 classification; PI-RADS 4-5 lesions carry a high probability for clinically significant prostate cancer.

It is used in patients on active surveillance to follow progression, in lesion localization before biopsy (MR-fusion biopsy), and in staging before radical prostatectomy.

Symptoms

High or rising PSA level
Suspicious finding on digital rectal examination
Persistent suspicion despite previous negative biopsy
Active surveillance follow-up of prostate cancer
Local staging of prostate cancer

Risk Factors

Gadolinium contrast allergy (rare)
Severe renal failure (NSF risk)
Pacemaker or non-MR-compatible implant
Severe claustrophobia
Large hip prosthesis (artifact)

When to See a Doctor?

If you experience any of the following symptoms, seek medical attention promptly:

  • When PSA continues to rise or remains elevated
  • When the urologist requests for biopsy targeting
  • When considering active surveillance
  • Before radical prostatectomy planning

Treatment Methods

01
Multiparametric MR protocol on a 3T or high-quality 1.5T device
02
T2-weighted, DWI, and DCE sequences
03
PI-RADS v2.1 scoring
04
MR-fusion biopsy guidance
05
Local staging report (extracapsular extension, seminal vesicle invasion)
