Prostate MRI Quality Assessment: PI-QUAL and Factors Influencing Image Quality

Area of Science:

• Radiology
• Medical Imaging
• Oncology

Background:

• Prostate MRI, guided by PI-RADS, is crucial for prostate cancer detection and staging.
• Image quality variations across institutions hinder diagnostic accuracy.
• Previous PI-QUAL v1 had limitations, including inability to assess biparametric MRI (bpMRI).

Purpose of the Study:

• To introduce the updated Prostate Imaging Quality (PI-QUAL) v2 scoring system.
• To address limitations of PI-QUAL v1 and enhance prostate MRI quality assessment.
• To provide a standardized framework for evaluating prostate MRI quality.

Main Methods:

• PI-QUAL v2 simplifies technical requirements and incorporates bpMRI assessment.
• A reproducible 3-point scale with adjustment rules was introduced.
• Factors like magnetic field strength and artifacts were considered.

Main Results:

• PI-QUAL v2 enhances reproducibility in prostate MRI quality assessment.
• The system balances quality assurance with diagnostic advantages of multiparametric MRI (mpMRI).
• It broadens clinical applicability for prostate MRI evaluations.

Conclusions:

• PI-QUAL v2 offers a practical framework for ensuring high-quality prostate MRI.
• Future improvements may involve standardized data collection and multidisciplinary collaboration.
• The system aims to improve diagnostic accuracy in prostate cancer detection.
