The goals of every modern neurosurgeon during surgery for intracranial tumors can be summarized as follows: 1) a small and less invasive craniotomy; 2) a resection as wide as possible; 3) the preservation of eloquent areas and white matter major tracts (WMMTs); and 4) the minimization of postoperative morbidity. The development of image-guided neurosurgery improved the microsurgical treatment o...

We describe a new magnetic resonance (MR) image analysis tool that produces cortical surface representations with spherical topology from MR images of the human brain. The tool provides a sequence of low-level operations in a single package that can produce accurate brain segmentations in clinical time. The tools include skull and scalp removal, image nonuniformity compensation, voxel-based tis...

background: accurate brain tissue segmentation from magnetic resonance (mr) images is an important step in analysis of cerebral images. there are software packages which are used for brain segmentation. these packages usually contain a set of skull stripping, intensity non-uniformity (bias) correction and segmentation routines. thus, assessment of the quality of the segmented gray matter (gm), ...

This technical report disrobes the first case in Intra-operative Magnatic Resonance Imaging operating theatre (iMRI OT) (BrainSuite), of Awake Craniotomy. The procedure was for frontal lobe glioma excision in 24 y. old man. He was scheduled to undergo eloquent cortex language mapping intra-operatively. He was motivated and was excited to see the operating theatre. He requested to take his photo...

Reconstruction of images in Electrical Impedance Tomography (EIT) of brain function in the adult head benefits from the use of accurate numerical models, which may utilize meshes created by the Finite Element Method (FEM). Previously, these have been produced by manual segmentation and parametric representation of surfaces which were later meshed, but this was time consuming and required CAD sp...

Sulcal and gyral landmarks on the human cerebral cortex are required for various studies of the human brain. Whether used directly to examine sulcal geometry, or indirectly to drive cortical surface registration methods, the accuracy of these landmarks is essential. While several methods have been developed to automatically identify sulci and gyri, their accuracy may be insufficient for certain...

Abstract Aim The hippocampus is involved in many functions; most importantly the short-term memory and consolidation. Hippocampal volume an important determinant for cognition, function as indicator development of diseases such Alzheimer’s, depression, schizophrenia. This study aimed to measure cortical structures young adult Sudanese examine effect sex, age, body mass index (BMI) education on ...

Abstract Aim The insula is important in gustatory (taste) and visceral sensations, pain, emotion, tactile senes. This study aimed to measure the cortical structure of young adults effect gender, age, Body mass index (BMI) education on it. will provide base line data about volume thickness normal subjects. Method A cross-sectional descriptive was done 60 individuals, their age ranged from 20–40 ...

Grey matter (GM) of the frontal lobe carries out its complex function such as muscle control, speech, decision making, and self-control; while white (WM) is a major contributor to human brain enlargement higher structural connectivity. This study was conducted assess effect sex age on grey volumes (GMV WMV) gyri in healthy young adult Sudanese. The present included 139 Sudanese subjects (80 mal...
