Brain zap test could make radiation safer for tumor patients

This study tests whether a brain mapping technique called navigated transcranial magnetic stimulation (nTMS) can help doctors plan radiation therapy better for people with brain metastases near the motor cortex. About 30 patients who had surgery for a brain tumor will get both a standard radiation plan and one adjusted using the nTMS map. The goal is to see if the map-based plan can deliver high radiation to the tumor while reducing exposure to healthy brain tissue that controls movement.
