Multiparametric MRI enhances bladder cancer detection and staging. The Vesical Imaging Reporting and Data System (VI-RADS) standardizes interpretation for improved accuracy in assessing tumor invasion.
Area of Science:
- Radiology
- Oncology
- Urology
Background:
- Multiparametric MRI (mpMRI) is crucial for bladder cancer detection and staging.
- The Vesical Imaging Reporting and Data System (VI-RADS) aims to standardize bladder MRI interpretation.
- Accurate assessment of muscularis propria invasion is vital for treatment planning.
Purpose of the Study:
- To provide a practical guide for bladder MRI acquisition and interpretation using VI-RADS.
- To discuss technical details, reporting tips, and potential challenges in clinical application.
- To review current evidence, controversies, and future directions for VI-RADS.
Main Methods:
- Review of technical aspects of bladder MRI acquisition protocols.
- Discussion of image evaluation and interpretation standards for VI-RADS.
- Synthesis of current literature on VI-RADS performance and clinical utility.
Main Results:
- Standardized protocols and interpretation enhance diagnostic accuracy and reproducibility of bladder MRI.
- VI-RADS improves the assessment of muscularis propria invasion.
- The review highlights practical considerations, pitfalls, and challenges in applying VI-RADS.
Conclusions:
- Adherence to standardized technical and interpretive guidelines is essential for optimal bladder MRI performance.
- VI-RADS offers a robust framework for bladder cancer staging, but ongoing refinement and validation are necessary.
- Further research is needed to address current controversies and knowledge gaps in VI-RADS application.
