Intraoperative MRI and Image-guided Frameless Neuronavigation
Neurosurgeons have long used various image-guided systems, such as fluoroscopy, ultrasound, and threedimensional (3-D) stereotaxy in an attempt to more accurately localize intracranial targets (34). The development of advanced neuroimaging techniques over the years has provided the neurosurgeon with increasingly more accurate and precise tools to aid in the microsurgical treatment of intracrani...
متن کاملAdvanced new neurosurgical procedure using integrated system of intraoperative MRI and neuronavigation with multimodal neuroradiological images.
The purpose of this paper is to describe the newly-established technique in the field of neurological surgery for fusion imaging of three-dimensional magnetic resonance image (3D-MRI) and/or three-dimensional computed tomography (3D-CT) for brain tumor surgery. Combining neuronavigation technology and intraoperative MRI, this method remarkably demonstrates spatial relationships of neurovascular...
متن کاملIntraoperative neurosonography revisited: effective neuronavigation in pediatric neurosurgery
Intraoperative ultrasonography (IOUS) is a widely used noninvasive method to evaluate the morphology, vasculature, and pathologies of the brain. The advantages of IOUS include realtime depiction of neuroanatomy, accurate localization and characterization of a lesion, reduced surgical exploration and surgical time, and presumably decreased patient morbidity. IOUS is useful in the intraoperative ...
متن کاملRisk reduction in dominant temporal lobe epilepsy surgery combining fMRI/DTI maps, neuronavigation and intraoperative 1.5-Tesla MRI.
BACKGROUND In dominant temporal lobe epilepsy surgery, speech, memory and visual systems are at risk. OBJECTIVE Functional magnetic resonance imaging (fMRI) and diffusion tensor imaging combined with intraoperative neuronavigation and MRI were investigated retrospectively regarding risk reductions for favorable neurological and seizure outcome. METHODS Functional imaging risk maps were gene...
متن کاملMultimodal image fusion in ultrasound-based neuronavigation: improving overview and interpretation by integrating preoperative MRI with intraoperative 3D ultrasound.
OBJECTIVE We have investigated alternative ways to integrate intraoperative 3D ultrasound images and preoperative MR images in the same 3D scene for visualizing brain shift and improving overview and interpretation in ultrasound-based neuronavigation. MATERIALS AND METHODS A Multi-Modal Volume Visualizer (MMVV) was developed that can read data exported from the SonoWand neuronavigation system...
