Nationwide Survey Reveals Gaps in Prostate MRI Standardization Across China

A 2023 survey of 3,919 Chinese hospitals found wide variability in prostate MRI practice: only 58.7% included high b-value diffusion-weighted imaging, and 55.3% still used unstructured reports — signaling major PI-RADS standardization gaps nationally.

• Cross-sectional survey (May–June 2023) of 4,620 eligible hospitals; 84.8% response rate; most were public tertiary centers. 61.2% used 1.5-T scanners; only 60.2% used both biparametric and multiparametric MRI protocols.
• Higher-volume institutions (above 75th percentile of annual exams) were significantly more likely to use 3.0-T scanners, perform full multiparametric MRI, include required sequences, and adopt PI-RADS structured reporting (all P < 0.05).
• Key limitation: self-reported survey data with no verification of actual scan quality or diagnostic performance; results reflect stated practice, not audited outcomes.
