VI-RADS (Panebianco and colleagues, European Urology 2018) standardises multiparametric MRI of the bladder and proposes a five-point score, built from T2-weighted, diffusion-weighted and dynamic contrast images, for the risk of muscle invasion. The authors do not advocate MRI for everyone with bladder cancer; they see it as most useful in non-muscle-invasive disease, in speeding radical treatment, and in judging response to bladder-sparing treatment. The American College of Radiology now lists it among its RADS and runs a works-in-progress committee on its implementation.","asOf":"2026-11-04","links":[{"label":"Panebianco et al., Multiparametric MRI for bladder cancer: development of VI-RADS (Eur Urol 2018)","url":"https://doi.org/10.1016/j.eururo.2018.04.029"},{"label":"American College of Radiology, VI-RADS","url":"https://www.acr.org/clinical-resources/clinical-tools-and-reference/reporting-and-data-systems/vi-rads"}],"tags":[],"related":["paris-system-urinary-cytology"],"cancers":["urothelial"],"sections":[],"technologies":["mri"],"targets":[],"drugs":[],"companies":[],"institutions":[],"pathways":[],"terms":[],"trials":[],"people":[],"bottlenecks":[],"keyPapers":[],"journals":[],"dependsOn":[],"notes":[],"category":"Diagnostics & imaging"},"route":"/terms/vi-rads/","neighbours":{"term":[{"id":"paris-system-urinary-cytology","kind":"term","name":"Paris System for Reporting Urinary Cytology","route":"/terms/paris-system-urinary-cytology/"},{"id":"pi-rads","kind":"term","name":"PI-RADS (Prostate Imaging Reporting and Data System)","route":"/terms/pi-rads/"}],"cancer":[{"id":"urothelial","kind":"cancer","name":"Bladder & urothelial cancer","route":"/cancers/urothelial/"}],"technology":[{"id":"mri","kind":"technology","name":"MRI","route":"/technologies/mri/"}]}}
