OBJECTIVE To determine the beneficial effects of intraoperative high-field magnetic resonance imaging (MRI), multimodal neuronavigation, and intraoperative electrophysiological monitoring-guided surgery for treating supratentorial cavernomas. METHODS Twelve patients with 13 supratentorial cavernomas were prospectively enrolled and operated while using a 1.5 T intraoperative MRI, multimodal ne...

CONTEXT Neuronavigation provides a patient-specific, three-dimensional (3-D) anatomy for preoperative planning and intraoperative navigation. However, the initial and maintenance costs are quite prohibitive, especially in the Indian scenario. AIMS To study the efficacy and limitations of neuronavigation, especially in the Indian scenario. SETTINGS AND DESIGN A prospective nonrandomized stud...

AIM To identify whether neuronavigation-assisted aspiration (NA) combined with electro-acupuncture (EA) provides better motor recovery in events of hypertensive putaminal hematoma (HPH) sized 30 to 50 ml. This study aims to examine whether neuronavigation-assisted aspiration and electro-acupuncture have additional value to cerebral hemorrhage motor rehabilitation. MATERIAL AND METHODS 240 pat...

Background and Aim: Numerous efforts over the past century have been performed. Various innovation techniques are increasingly gaining attention and gradually established the foundation of recent significant developments in the world of neurosurgery, among which varied stereotactic neuro-navigation designs and other novel emerging systems are being quotidian developed. This narrative review ai...

The authors report their experience with image-based preoperative vascular and neural element segmentation with three-dimensional (3D) reconstruction for intraoperative guidance in ten patients undergoing surgery for skull base tumor resection. In all cases, the 3D segmented structures were correlated to the correspondent intraoperative findings with the aid of neuronavigation. They conclude th...

According to its location, the surgical treatment of intracranial meningioma can be of considerable challenge for the neurosurgeon. Image-guided surgery essencially provides intraoperative localization for dynamic navigation and, also, improves the surgical planning. The continuous development of neuroimaging and computated technology promotes continuous improvement of navigation techniques and...

Neuronavigation is a kind of image-guided surgery used during neurosurgical procedures. Based on specific equipment which is compatible with the software calculating and processing the patient's data; this method allows the determination of the location of anatomical structures and visualisation of surgical instruments in the operative field. Although standard brain dissection is still the best...

OBJECTIVE Intraoperative localisation of the sensorimotor cortex using the phase reversal of somatosensory evoked potentials (SEPs) is an essential tool for surgery in and around the perirolandic gyri, but unsuccessful and perplexing results have been reported. This study examines the effect of tumour masses on the waveform characteristics and feasibility of SEP compared with functional neurona...
