Serial Magnetic Resonance Imaging for the Prediction of Radiation-Induced Changes in Normal Tissue of Patients With Oral Cavity or Skull Base Tumors

This phase IV trial studies how well serial magnetic resonance imaging (MRI) after radiation therapy works in predicting radiation-induced changes in the normal tissue of patients with oral cavity or skull base tumors. Performing MRIs after radiation therapy for patients with oral cavity or skull base tumors may help to predict osteoradionecrosis (a change in non-cancerous tissue).
