Whether bladder cancer has muscle invasion determines the choice of treatment options and prognosis.
Whether bladder cancer has muscle invasion determines the choice of treatment options and prognosis.
Recently, a study published in the journal European Radiology evaluated the diagnostic performance of the Bladder Imaging Report and Data System (VIRADS) and determined a quantitative index that complements VIRADS to predict bladder cancer myometrial invasion.
This study retrospectively analyzed 82 patients who underwent 3-T MRI before transurethral bladder tumor resection or radical cystectomy from July 2018 to June 2019.

This study shows that VIRADS evaluation is a good predictor of muscle invasion.
