From: White matter hyperintensity patterns: associations with comorbidities, amyloid, and cognition
Principal component analysis identified four patterns of hyperintensity signal distribution. Plots show the loading in each parcel for each component in the bullseye representation. The concentric rings in the Bullseye diagram delineate the area between the ventricular surface and the cortex into four equidistant layers. The interior parcels in the plot represent the most periventricular area, and the most external parcels correspond to the regions below the cortex. The corpus callosum (CC) was divided into anterior (inner parcel) and posterior (external parcel) regions. Only loadings > 0.4 are shown in the plots. Abbreviations: BGT = basal ganglia & thalamus; CC = corpus callosum; FL = frontal lobe; OL = occipital lobe; PL = parietal lobe; TL = temporal lobe
