Study Description

Brief Summary: This study will apply novel MRI approaches with established sensitivity to tissue oxygen consumption and perfusion to predict hypoxia-associated radiation resistance, manifested as tumor recurrence and progression post-treatment.

Detailed Description: Primary Objective: - To validate non-invasive, MRI-based markers of tumor hypoxia in patients with brain metastases or head and neck cancer with and without evidence of tumor hypoxia identified by 18F-FMISO-PET-CT. Secondary Objectives: * To assess treatment-related changes in tumor and peritumoral tissue oxygen consumption and perfusion via non-invasive MRI. * To evaluate the effect of pre-treatment and post-treatment (3 months) tumor hypoxia on tumor recurrence, progression, and radiation necrosis in patients with central nervous system metastases treated with standard of care stereotactic radiosurgery.
