MRI scans to tell tumor spread from radiation injury
Part of Brain & nervous system, Cancer clinical trials.
This trial studies how a special MRI can help doctors tell whether brain lesions after Gamma Knife treatment are growing tumors or radiation injury. It may help you avoid unnecessary treatment if the findings suggest radionecrosis instead of progression.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have confirmed cancer that has spread to the brain
- You had Gamma Knife treatment within the last 4 months
- Your recent scans suggest worsening that could be tumor growth or radiation injury (at least 25% change in size)
- The MRI shows an enhanced brain lesion that is at least 1 centimeter
- You can have MRI scans (no metal/other MRI issues and you’re not allergic to the MRI contrast dye)
- You can give consent and you’re able to complete follow-up scans; you are not in another study

This study looks at how a specific kind of MRI picture (called the CEST sequence) can help characterize radiation-related brain injury and changes in brain metastases from lung cancer. It may help doctors better interpret follow-up scans after radiation, without changing your cancer treatment.
This study tests a special MRI technique to better distinguish between tumor regrowth and radiation-related changes in people with brain tumors. If you've had radiation for a brain tumor and now have suspicious changes, this scan might help guide your next steps.
This study tests a new way of using a PET scan to look at brain tumors that have spread from other cancers, before and after focused radiation treatment. The goal is to see if this scan can better predict how well the radiation works.
This study uses MRI scans to figure out whether an enlarging spot in the brain after stereotactic (focused) radiation is still living tumor or dead tissue. It may help doctors better understand what’s happening after radiation and guide next treatment decisions.
This study uses an advanced MRI scan to help doctors tell the difference between radiation scar (radiation necrosis) and returning glioma (recurrent glioma) after prior treatment. It may help guide the next steps for care if you have a new or changing brain lesion.
This trial tests whether using advanced MRI scans before radiation therapy can help doctors target the tumor more precisely and possibly improve outcomes for people with glioblastoma. It aims to make radiation treatment more personalized.
