Read our Urinary Bladder Neoplasms research guide →Phase 1 — Testing in a small group (usually 20–80 people) to find a safe dose and watch for side effects.
This trial is testing a new type of MRI scan that uses special contrast dyes (Gadobutrol and Ferumoxytol) placed directly into the bladder to create detailed images of bladder cancer. The goal is to see if this imaging method can accurately determine how deep the cancer has spread into the bladder wall—information that helps doctors plan the best surgical approach. You would receive this single scan 1 to 6 days before your already-scheduled surgery.
Currently, doctors stage bladder cancer partly by guessing based on standard imaging, which isn't always accurate. This new scan method aims to give surgeons a clearer picture of exactly how far the cancer has invaded, so they can make better decisions about what type of surgery you need.

You will come for a single MRI scan appointment 1 to 6 days before your scheduled surgery. During the scan, doctors will place a temporary catheter (small tube) into your bladder and instill a special contrast solution, then remove the catheter and take MRI images. The whole process takes about an hour. After the scan, you will proceed with your surgery as already planned—this MRI is an extra diagnostic test to help your surgical team.
