Figure 1. Association between pericarotid fat and MRI markers of CSVD. Pericarotid fat density was associated with the presence of lacunes, (A) for mean HU, and (B) for maximum HU. Pericarotid fat density was associated with the different grades of WMHs, (C) for mean HU, and (D) for maximum HU. In the box-and-whisker plots, the lower and upper ends of the box represent the 25th and 75th percentiles, and the peripheral lines extending to the outer fences represent the 10th and 90th percentiles, respectively. *<0.05; **<0.01. Abbreviation, WMHs, white matter hyperintensities, HU, hounsfield unit.
