MRI and 18F-Fluoromisonidazole PET/CT Scan for Assessing Tumor Hypoxia and Guiding Adaptive Radiation Therapy in Patients With Head and Neck Cancer or Brain Metastases

This clinical trial is studying how well magnetic resonance imaging (MRI) in combination with 18F-fluoromisonidazole (18F-FMISO) positron emission tomography (PET)/computed tomography (CT) scans works in assessing a decrease in the amount of oxygen (hypoxia) in tumor cells and in guiding adaptive radiation treatment in patients with head and neck cancer or cancer that has spread to the brain from where it first started (brain metastasis). Both head and neck cancer and brain metastases can be treated with radiation. Previous research studies have shown that the amount of oxygen that goes towards cancer cells prior to their radiation treatments predicts how the cancer cells will respond to radiation treatment. MRI is a type of imaging technique that uses radio waves and large magnets to produce detailed images of areas inside the body. 18F-FMISO is a radioactive substance that binds to hypoxic tumor cells and emits radiation, allowing the tumor cells to be visualized using PET/CT, which is an imaging technique that combines PET and CT in a single machine. It is used to make detailed, computerized images of inside the body. By combining MRI with 18F-FMISO PET/CT, researchers may be able to develop an MRI sequence that can be used to evaluate hypoxia in tumor cells and predict response to treatment in patients with head and neck cancer or brain metastases.
