This study is aimed at determining the predictive value of the gray-matter–white-matter ratio (GWR) on brain computed tomography for delayed encephalopathy after acute carbon monoxide (CO) poisoning (DEACMP). Methods This retrospective cohort study reviewed 352 patients with acute CO poisoning and...
Head ultrasonography (HUS) is a reliable and easy to perform bedside imaging technique that can give valuable information about degree of brain injury/edema after perinatal asphyxia in term neonates. The goals of our study were to determine whether semiq
Patients with bipolar disorder (BD) show alterations in both gray matter volume (GMV) and white matter (WM) integrity compared with healthy controls (HC). However, it remains unclear whether the phenotypically distinct BD subtypes (BD-I and BD-II) also exhibit brain structural differences. This...
Female white matter in the brain is 10 times that of men, while men use the gray matter of the brain is 6.5 times that of women. The gray matter contains the information processing center, the role of the white matter of the information processing centers are joined together to form a ne...
Although there were significant gender differences in gray matter volume (P < 0.001; t, −9.214) and white matter volume (P < 0.001; t, −8.116), no significant gender difference in the gray matter ratio (P, 0.918; t, 0.103) or the white matter ratio (P, 0.918; t, 1.064) was ...
Magnetic resonance imaging (MRI) findings in 87 children with various clinical entities were used to determine the signal intensity ratio of gray/white matter in T1- and T2-weighted images using a 1.5 T MR Scanner. Signal intensity ratio changes in both T1- and T2-weighted images correlated we...
Gray matter (GM) atrophy and white matter lesions (WML) have been described in both conditions. Our aims were to determine the relationship of GM and WML with cognition and depressed mood in the same population. Structural brain images were obtained from 42 controls, 20 Alzheimer's disease (...
A universal scaling law between gray matter and white matter of cerebral cortex. Presents an analytical theory for the gross organization of cortical gray matter and the associated white matter of the cerebral cortex. Close relationship... K Zhang,Sejnowski,J Terrence - 《Proceedings of the ...
Gray/white matter contrast (GWC) decreases with aging and has been found to be a useful MRI biomarker in Alzheimer's disease (AD), but its utility in Parkinson's disease (PD) patients has not been investigated. The aims of the study were to test whether GWC is sensitive to aging changes...
