This study is comparing two types of scans to see their effects on blood vessels in the neck for patients receiving radiation therapy for head and neck cancer. The standard scan uses a substance called F-18 FDG and combines PET (positron emission tomography) and CT (computed tomography) scans to create detailed images. Another type of scan being tested uses F-18 NaF, which might offer a better view of changes in blood vessels. Radiation therapy, aimed at treating cancer, can affect the neck's blood vessels that supply blood to the brain. The study has two parts: one for patients receiving a type of radiation called IMRT and another for IMPT. The aim is to see if the F-18 NaF PET/CT scan works as well or better than the standard scan. This study involves a few visits for imaging and requires adult patients who are undergoing radiation therapy for certain types of head and neck cancer.
- Duration: Imaging done before and 12 weeks after radiation therapy.
- Eligibility: Adults 18+, specific cancer stages, and treatment plans.
- Exclusions: Pregnant women, recent chemotherapy, and severe heart issues.
