WebApr 14, 2024 · Clinically, electroencephalogram (EEG) or functional Magnetic Resonance maging (fMRI) is often for detecting changes in brain function, and T1 structural imaging and Diffusion Tensor Imaging (DTI) are for detecting structural changes in gray and white matter ( Xiao et al., 2016 ). WebSep 1, 2000 · Background and Purpose—Anecdotal reports suggest that a loss of distinction between gray (GM) and white matter (WM) as adjudged by CT scan predicts poor outcome in comatose patients after cardiac arrest.To address this, we quantitatively assessed GM and WM intensities at various brain levels in comatose patients after cardiac arrest.

WebNov 30, 2015 · Width of the third ventricle, width of the central sulcus, and attenuation in gray matter (GM) and white matter (WM) from the same area of the basal ganglia, centrum semiovale, and high convexity were statistically compared between AMCT and PMCT. WebTo establish the normal appearance of the neonatal brain, 51 neonates, 29-42 weeks postconception, underwent magnetic resonance (MR) imaging with a 0.6-T magnet in a prospective study. T1-weighted images were used to devise stages for the appearance of gray-white matter differentiation and extent of myelination. The results show that from … haimatulehdus röyhtäily
