Bladder MRI: VI-RADS quality control, treatment response, and AI — a pictorial review

Multiparametric MRI with VI-RADS reliably separates muscle-invasive from non-muscle-invasive bladder cancer, but clinical utility hinges on quality control, reducing reader variability, and integrating AI—this review covers implementation, post-treatment response, and AI solutio…

• The VI-RADS Quality Score helps identify technically inadequate exams.
• Post-therapy scoring (nacVI-RADS) and quantitative biomarkers are emerging for response assessment.
• AI may assist with scan acceleration, quality auditing, segmentation, and equivocal lesion evaluation.
