A Pilot Trial of Image-Guided Adaptive Radiotherapy for Head and Neck Cancer

The goal of this clinical research study is to use computed tomography (CT) scans to measure and guide your radiation therapy. Researchers want to learn if the CT scans can be used to adapt radiation therapy to the changes in normal tissue and to the shrinking of the tumor that may occur as a reaction to radiation therapy. Researchers also want to see if magnetic resonance imaging (MRI) scanning can detect certain changes in the tumor any earlier than with standard tests.
