… differences in premorbid gray/white matter signal properties across the … gray to white matter
signal intensity (GWR) at each point along the cortical surface to determine whether contrast …

… gray and white matter contrast up to 10-fold higher compared to conventional magnitude
images. However, the underlying contrast … to in vivo phase image contrast. Therefore, magnetic …

… improved the contrast between the gray and white matter structures. In general, the higher
the iron content or subvoxel field inhomogeneities, the higher was the contrast, and the …

… , 32, and cortical gray matter (GM) … gray/white matter contrast (GWC) of the T1-signal intensity.
Lower GWC indicates that GM and WM intensities are more similar, while a higher contrast …

… Gray/white matter contrast (GWC) decreases with aging and has been found to be a useful
… GWC was computed by dividing the white matter (WM) by the gray matter (GM) values and …

… It has been proposed that gray/white matter T1w contrast (GWC) that measures the blurring
between gray matter (GM) and WM boundaries (GW/WM) can capture local variations in …
