Awake craniotomy offers many advantages to brain tumor surgery, since it allows neurosurgeons to maximize surgical resection, while minimizing neurologic risks. Is this procedure well tolerated by most patients? What role does MRI mapping play in awake craniotomy? Dr. Donald O'Rourke, associate professor of neurosurgery at the University of Pennsylvania Neurological Institute and the Abramson Cancer Center at Penn Medicine, discusses the exciting advances being made with awake craniotomy with host Dr. Lee Freedman.
