mpMRI Compared to Diagnostic TURBT in Patients With Suspected Muscle-Invasive Bladder Cancer

This study is comparing two approaches to diagnose muscle-invasive bladder cancer: an advanced MRI scan (mpMRI) versus the traditional surgical procedure (diagnostic TURBT, where a small scope removes tumor tissue for testing). The goal is to determine if MRI can accurately stage the cancer without requiring surgery first. **You may be eligible if...** - You are 18 years or older - Your doctor suspects you have muscle-invasive bladder cancer based on an initial cystoscopy (bladder inspection) - You have a good enough functional status (ECOG 0–3) - You are willing and able to follow the study schedule **You may NOT be eligible if...** - You had a TURBT or any bladder cancer treatment within the past 120 days - You are unable to tolerate an MRI (e.g., have a pacemaker, metal implants, or severe claustrophobia) - You are pregnant Talk to your doctor to see if this trial is right for you.
