Unveiling the Global Disparities in Prostate MRI Quality
When it comes to prostate cancer detection, the quality of MRI scans can be a game-changer. A recent study published in Radiology delves into this very issue, evaluating MRI quality on a global scale. The study’s findings are both enlightening and alarming, revealing significant variations in MRI quality across different countries.
The study employed the Prostate Imaging Quality (PI-QUAL) standardized scoring system to assess MRI quality. The results? A mixed bag of scores, with some centers achieving optimal quality and others falling short.

The Source Article's Abstract
High variability in prostate MRI quality might reduce accuracy in prostate cancer detection.
To prospectively evaluate the quality of MRI scanners taking part in the quality control phase of the global PRIME (Prostate Imaging Using MRI Â± Contrast Enhancement) trial using the Prostate Imaging Quality (PI-QUAL) standardized scoring system, give recommendations on how to improve the MRI protocols, and establish whether MRI quality could be improved by these recommendations.
Materials and Methods
In the prospective clinical trial (PRIME), for each scanner, centers performing prostate MRI submitted five consecutive studies and the MRI protocols (phase I). Submitted data were evaluated in consensus by two expert genitourinary radiologists using the PI-QUAL scoring system that evaluates MRI diagnostic quality using five points (1 and 2 = nondiagnostic; 3 = sufficient; 4 = adequate, 5 = optimal) between September 2021 and August 2022.
In phase I, 41 centers from 18 countries submitted a total of 355 multiparametric MRI studies from 71 scanners, with nine (13%) scanners achieving a PI-QUAL score of 3, 39 (55%) achieving a score of 4, and 23 (32%) achieving a score of 5. Of the 48 (n = 71 [68%]) scanners that received feedback to improve, the dynamic contrast-enhanced sequences were those that least adhered to the Prostate Imaging Reporting and Data System, version 2.1, criteria (44 of 48 [92%]), followed by diffusion-weighted imaging (20 of 48 [42%]) and T2-weighted imaging (19 of 48 [40%]).

What the PI-QUAL Scoring System Tells Us
The PI-QUAL scoring system is a standardized metric that evaluates the diagnostic quality of MRI scans. The scores range from 1 to 5, with 1 and 2 being nondiagnostic, 3 being sufficient, 4 being adequate, and 5 being optimal. The study found that only 32% of the MRI scanners achieved an optimal score of 5.
This raises concerns about the reliability of MRI scans in prostate cancer detection, especially in centers that scored low on the PI-QUAL scale. The study also provided feedback to these centers, aiming to improve their MRI protocols.
Key Takeaways for Medical Professionals
- Global Variation: The study highlights the need for standardized protocols in MRI quality.
- Room for Improvement: Centers with low PI-QUAL scores have actionable feedback to enhance their MRI quality.
- Implications for Patient Care: Improved MRI quality can lead to more accurate prostate cancer detection, impacting patient outcomes.
