Multi-parameter Magnetic Resonance Imaging Guides Precise Treatment of Urothelial Carcinoma

Summary

Purpose：To evaluate whether immediate multiparametric MRI evaluate the sensitivity of modified neoadjuvant chemotherapy early in patient with muscle invasive bladder cancer（MIBC）. Rationale：Multiparametric MRI may help detect the early changes of bladder cancer receiving neoadjuvant chemotherapy.
