BACKGROUND Intraoperative magnetic resonance imaging (iMRI) combined with optic radiation neuronavigation may be safer for resection of cerebral lesions involving the optic radiation. OBJECTIVE To investigate whether iMRI combined with optic radiation neuronavigation can help maximize tumor resection while protecting the patient's visual field. METHODS(More)
Between March 2009 and January 2010, 36 patients with 38 supratentorial cavernous malformations in eloquent brain areas underwent surgery with the aid of intraoperative MRI (iMRI), functional neuronavigation, and electrocorticography (ECoG). To optimize outcomes, the hemosiderin-stained tissue surrounding the lesion in addition to the cavernous malformation(More)
AIM To explore the clinical value of combining pyramidal tract mapping, microscopic-based neuronavigation, and intraoperative magnetic resonance imaging (iMRI) in the surgical treatment of epileptic foci involving sensorimotor cortex. MATERIAL AND METHODS We retrospectively analyzed 69 patients with focal epilepsy involving motor and sensory cortex. The(More)
BACKGROUND Despite improvements in microsurgical technique and the use of intraoperative electrophysiological monitoring, the potential for facial and cochlear nerve injury remains a possibility in the resection of vestibular schwannomas (VS). We reviewed a series of 221 cases of VS resected via a retrosigmoid approach at our institution from October 2008(More)
BACKGROUND The utility of virtual and augmented reality based on functional neuronavigation and intraoperative magnetic resonance imaging (MRI) for glioma surgery has not been previously investigated. METHODS The study population consisted of 79 glioma patients and 55 control subjects. Preoperatively, the lesion and related eloquent structures were(More)
BACKGROUND This study investigated whether functional neuronavigation can be used to remove lesions in the lateral ventricle while preserving patients' neurologic functionality. METHODS A total of 60 patients with lateral ventricular meningiomas were divided into study and control groups (n = 30 each). Diffusion tensor and blood oxygenation(More)
OBJECTIVE Endoscopic removal of intracerebral hematomas is becoming increasingly common, but there is no standard technique. The authors explored the use of a simple image-guided endoscopic method for removal of spontaneous supratentorial hematomas. METHODS Virtual reality technology based on a hospital picture archiving and communications systems (PACS)(More)
OBJECTIVE To explore the practicability of resecting small lesions in deep brain by intraoperative magnetic resonance imaging (iMRI) and neuronavigator-assisted microsurgery and its clinical efficacies. METHODS A total of 42 cases with small lesions in deep brain underwent intraoperative MRI and neuronavigator-assisted microsurgery. The drifting of(More)
OBJECTIVE To explore the clinical value of intraoperative magnetic resonance imaging (MRI) and functional neuronavigation in the preservation of the language function during microsurgery for lesions near language-related brain regions. METHODS Sixty-one right-handed patients underwent microsurgical resection of the lesions near the language-related brain(More)
OBJECTIVE To investigate the feasibility of applying diffusion tensor imaging (DTI)-based arcuate fasciculus tractography and intraoperative arcuate fasciculus navigation for neurosurgery. METHODS Totally 85 patients with interhemispheric tumors who had undergone intra-operative magnetic resonance imaging (MRI) and neuronavigation were divided into(More)
