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.

This is an AI summary of the original study and may miss details. Read our disclaimer.
