Could a simple MRI replace costly PET scans for brain tumors?
NCT ID NCT05937776
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a new way of analyzing MRI scans, called activity MRI (aMRI), to see if it can measure brain tumor activity as well as PET scans. Four adults with glioma had both aMRI and standard PET imaging. The goal was to check if aMRI results match PET findings, which could make metabolic imaging cheaper and more widely available.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, aMRI could offer a more accessible and less expensive way to monitor brain tumor activity without radioactive tracers.
- What could go wrong
- This is a very small, early observational study with only 4 participants. The new MRI method may not match PET accuracy and needs much larger validation.
