Abstract:
Functional magnetic resonance imaging (MRI) can be used for non-invasive mapping of cerebral cortex. The purpose of the study was evaluation of applicability of functional MRI for studies of neurosurgical patients. 32 volunteers (mean age 37.8 +/- 20.9 years) and 16 patients with brain tumors (mean age 36.2 +/- 24.2 years) were included in the study. Statistical analysis of the data obtained was performed. Activation maps were superimposed on anatomical images and discussed with neurosurgeons. Functional MRI studies were successful in localising the motor cortex and Broca's area in 89% of cases. In 69% of cases, results of the functional MRI influenced the patients' treatment.
