title: Use of a frameless isocentric stereotactic system (NEURO-SAT) combined with the intraoperative microrecording.
abstract: Combining the frameless isocentric stereotactic system (NEURO-SAT) and intraoperative microrecording, we performed stereotactic biopsies of deep-seated brain tumors in two cases. Case 1 was a 58-year-old male suffering from a right thalamus to basal ganglia tumor and case 2 was a 29-year-old male suffering from brain stem tumor. In both cases, the border between the tumor and the normal tissue was ambiguous on neuroimagings. NEURO-SAT provides three-dimensional real-time surgical navigation by displaying the positional information on the MRI images, and intraoperative microrecording shows a clear delineation between the tumor and the normal tissue in both cases. Therefore, since this combined method provides real-time surgical navigation and clear delineation of the tumor and normal tissue, it is a promising method of accurate and reliable image-directed stereotactic biopsy of deep-seated brain tumor.
