Diagnostic performance of the vesical imaging-reporting and data system for detecting muscle-invasive bladder cancer based on tumor locations.

The VI-RADS criterion was reported to have limitations, particularly for tumors location. So we evaluated the diagnostic performance of Vesical Imaging-Reporting and Data System (VI-RADS) scoring and diagnostic accuracies based on tumor locations. VI-RADS had superior diagnostic performance for detecting MI, especially in tumors located at the bladder lateral, posterior walls and ureteric orifices.
