Introduction: Literature on neuroprognostication suggests that gray-white matter ratio (GWR) measured from head computed tomography (CT) within two hours after return of spontaneous circulation (ROSC) can't adequately predict neurological outcomes in out-of-hospital cardiac arrest (OHCA) patients. ...
We accurately measured white matter (WM) and gray matter (GM) from three-dimensional (3D) volume studies, using a fuzzy classification technique. The new segmentation method is a modification of a recently published method developed for T1 parametric images. 3D MR images were transformed into pseu...
The meaning of WHITE MATTER is neural tissue especially of the brain and spinal cord that consists largely of myelinated nerve fibers bundled into tracts, has a whitish color, and typically underlies the cortical gray matter.
White matter disease is the wearing away of tissue in the largest and deepest part of yourbrain. The loss of white matter function has a number of causes, including aging. This tissue contains millions ofnervefibers, or axons, that connect other parts of the brain and spinal cord and signal...
While in this photograph, the gray matter is more of a yellowish cream, the white matter is as a white as the name would imply. The boundaries where the gray matter and the white matter come together are known as the “gray matter/white matter interface.” In such areas, there is a ...
We aimed to evaluate whether white and gray matter microstructure changes observed with magnetic resonance imaging (MRI)-based diffusion tensor imaging (DTI) can be used to reflect the progression of chronic brain trauma. The MRI-DTI parameters, neuropat

The gray-matter volumes ipsilateral to the angioma were smaller in all children, with the posterior regions underneath the angioma the most affected. In the infants, the white-matter volumes were increased in the region of the angioma, whereas in the regions remote from the angioma in the ...
The proposed algorithm is applied to challenging applications: gray matter/white matter segmentation in magnetic resonance image (MRI) datasets. The experimental results show that the proposed technique produces accurate and stable results. 展开
4.1. White matter models: Promise and limitations We introduced a pipeline to create a simple yet realistic biophysical model to simulate the MRI ME-GRE signal. These WM models contain real axon shapes and a g-ratio variability similar to what is reported in tissue samples, and have varying ...
