The recent discovery that magnetic resonance imaging can be used to map changes in brain hemodynamics that correspond to cortical operations has extended traditional anatomical imaging to include maps of human brain function. The ability to observe both the structures and also which structures participate in specific functions has opened new opportunities to plan neurosurgical operations and to judge surgical risks.
Neurosurgery relies on precise delineation of the structural and functional aspects of brain. Individualized maps of brain function are required when the presence of a tumour alters the expected location of a function, or when the location of the tumor is in an area with an eloquent function such as association cortices or language-related processes.
Functional MRI studies to support preoperative planning and intraoperative navigation have been performed in the practice of this Department in the past 5 years. Patients suffering from intracranial tumours, vasculars malformations or from intractable epilepsy have received a standard battery of tasks targeted to localize language, sensory, motor and visual areas both as candidates for surgery and as post-surgical patients.
Several examples will be presented to illustrate the potential advantage of functional plus anatomical information for surgical neurooncology and intractable epilepsy.
Clinical value of functional imaging as rergards to the outcome and safety of neurosurgical procedures have also been assessed and will be presented.
