Can VI-RADS/ADC Accurately Stage Bladder Cancer??

Can Vesical Imaging-Reporting And Data System and Apparent Diffusion Coefficient Values (the VI-RADS/ADC) Accurately Predict Non-Muscle Invasive Bladder Cancer

Vesical Imaging-Reporting And Data System (VI-RADS) is proposed for predicting muscle invasive bladder cancer (MIBC) using multi-parametric MRI. However, No validation study on VI-RADS has been reported yet. Apparent diffusion coefficient (ADC) values on diffusion-weighted MRI are reportedly significantly lower in MIBC than those in non-MIBC(NMIBC).

We aim to examine the accuracy of VI-RADS for predicting MIBC in final histopathology specimen. To assess whether incorporating ADC into VI-RADS improves the MIBC predictive accuracy of VI-RADS
