The accuracy of Vesical Imaging-Reporting and Data System (VI-RADS): an updated comprehensive multi-institutional, multi-readers systematic review and meta-analysis from diagnostic evidence into future clinical recommendations

1

VI-RADS is a standardized 5-point scale assessing muscle invasiveness in bladder cancer using multiparametric MRI before TURBT.
2

Meta-analyses indicate VI-RADS shows excellent performance in distinguishing non-muscle invasive from muscle invasive bladder cancer.
3

Ongoing studies are exploring VI-RADS's flexibility for guiding therapeutic decisions across various stages of bladder cancer.
4

Key challenges include optimizing diagnostic settings, ensuring reproducibility across MRI scanners, and defining cut-off criteria for muscle invasiveness.
5

A systematic review was conducted to evaluate VI-RADS's diagnostic performance, focusing on studies with GU radiologists and appropriate MRI protocols.
