BOLD fMRI and DTI in Sparing Cognitive Effects in Patients with Brain Lesions Undergoing Intracranial SRS

Trial Status: active

This trial studies how well advanced brain imaging such as blood oxygen level-dependent (BOLD)-function magnetic resonance imaging (fMRI) and diffusion tensor imaging (DTI) can be incorporated into the planning of intracranial stereotactic radiosurgery (SRS) in helping spare cognitive effects in patients with brain lesions. Intracranial SRS uses high, ablative doses of radiotherapy directed at the tumor or lesion, with no regard for critical white matter or cortical structures. Diagnostic procedures such as BOLD-fMRI looks at how the brain processes different types of information, such as movement, language, and memory (cognitive processes). Using BOLD-fMRI and DTI to plan SRS may spare critical brain regions and structures from high doses of radiation, which may reduce the cognitive effects of radiation injury in many patients with brain lesions.
