Study Description

Brief Summary: This pilot clinical trial studies how well voxel based diffusion tensor imaging in predicting response in patients with brain metastases undergoing whole-brain radiation therapy or stereotactic radiosurgery. Voxel based diffusion tensor imaging (VB-DTI) may allow doctors to measure response to whole brain radiation therapy or stereotactic radiosurgery earlier than is possible with a standard magnetic resonance imaging. The earlier ability to measure response may allow for consideration of alternative therapies at an earlier stage.

Detailed Description: PRIMARY OBJECTIVES: I. To determine if voxel based diffusion tensor imaging will provide an early predictive assessment of therapy response, as compared to radiographic volumetric response criteria. OUTLINE: Patients undergoing whole-brain radiation therapy (WBRT) for a total of 10 fractions also undergo VB-DTI magnetic resonance imaging (MRI) at baseline, 1 week after WBRT initiation, and 7-11 days after completion of WBRT. Patients undergoing stereotactic radiosurgery (SRS) without WBRT also undergo VB-DTI MRI at baseline and 7-11 days after completion of SRS. After completion of study, patients are followed up every 2 months for 6 months and then every 6 months until death.
