Can MRI make cancer radiation smarter? new study investigates
NCT ID NCT05919290
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is testing whether repeated MRI scans during radiation therapy for head and neck cancer can help doctors see how the tumor is responding. About 173 people with newly diagnosed head and neck cancer will get extra MRI scans during their standard treatment. The goal is to learn if these scans can guide more precise radiation and predict outcomes.
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, this could help doctors personalize radiation therapy by using MRI to see how tumors respond during treatment.
- What could go wrong
- This is an early-stage observational study, not testing a new treatment. It may not lead to changes in standard care.
