Learning objectives The aim of this study is to offer an overwiew of the Vesical Imaging Reporting and Data System (VI-RADS), highlight its importance in the diagnosis and management of bladder cancer, and explain its application in daily practice.
Read more Background Bladder cancer is a major health concern, ranking among the most common malignancies worldwide and one of the costliest to treat. Accurate imaging plays a crucial role in diagnosis and treatment planning.The classification of bladder cancer into non-muscle-invasive (NMIBC) and muscle-invasive (MIBC) forms is based on whether the tumor has infiltrated the muscle layer. This distinction significantly influences clinical management strategies and prognosis. While NMIBC is typically managed through transurethral resection of bladder tumors (TURBT), MIBC often requires radical cystectomy...
Read more Findings and procedure details The staging of bladder lesions relies on evaluating muscle invasion. On T2-weighted imaging (T2WI), the detrusor muscle appears as a low-signal intensity line along the bladder wall, showing intermediate signal intensity on diffusion-weighted imaging (DWI) without early enhancement on dynamic contrast-enhanced imaging (DCE). An interruption in this hypointense line is a key indicator of muscle invasion. Additionally, DWI can detect areas of diffusion restriction, which are typical of urothelial carcinoma, appearing hyperintense on DWI with corresponding hypointensity on the apparent...
Read more Conclusion The integration of VI-RADS into clinical practice enhances the accuracy of bladder cancer staging and management. By providing a standardized framework, VI-RADS improves communication among healthcare professionals and ultimately supports better patient outcomes. Future studies will further validate its efficacy and refine its application in routine clinical settings.
