New scan may spare bladder cancer patients from surgery
NCT ID NCT04321707
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a special type of PET/MR scan (using radioactive water) can accurately tell if bladder cancer has been completely eliminated by chemotherapy. 13 patients with muscle-invasive bladder cancer were scanned before and after chemotherapy, and the results were compared to the actual tissue removed during surgery. The goal is to find a non-invasive way to identify patients who are cancer-free and might safely avoid bladder removal.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
15O-H2O PET/MR scan
What this could lead to
If successful, this scan could help identify bladder cancer patients who are cancer-free after chemotherapy, allowing them to keep their bladder instead of having it removed.
What could go wrong
This is a very small, early study with only 13 participants. The scan may not be accurate enough to replace standard surgery, and more research is needed.
