Could a simple MRI replace a PET scan for safer cancer radiation?

NCT ID NCT07609225

First seen May 27, 2026 · Last updated Jun 23, 2026 · Updated 4 times

Summary

This study will test whether a special MRI scan (CSE-MRI) can accurately measure active bone marrow in men with metastatic prostate cancer, compared to a standard PET scan using a radioactive tracer (FLT). Fifteen participants will receive both scans at the same time using a combined PET/MRI machine. If the MRI works as well as the PET scan, it could help doctors better protect bone marrow during radiation therapy, reducing side effects.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

18F-FLT (fluorothymidine) injection

What this could lead to

If successful, this could show that a simpler MRI scan can replace a PET scan for measuring active bone marrow, potentially making radiation therapy safer and more accessible.

What could go wrong

This is a very small, early-phase study with only 15 participants. It is testing imaging accuracy, not a treatment, so it will not directly improve health outcomes. The MRI method may not prove as reliable as PET.
