Computer aided neurosurgery is now a highly advanced and essential technique, especially for the gliomas in the vicinity to the eloquent areas or deep inside of the brain. The intraoperative MRI (iMRI) is an important tool for the computer navigation system, considering brain shift under craniotomy. Real time navigation by the iMRI with brain mapping by subcortical stimulation and verbal confirmation by awake craniotomy can lead to the safe and precise tumor resection. The usefulness of an intraoperative low-field open MRI is defined for neuronavigation, especially for demonstration of the pyramidal tract in relation to the precise tumor location, considering brain shift during the operative procedure, to avoid tract injury.
