Figure 1. Group analysis on susceptibility-weighted imaging exhibiting higher susceptibility-weighted imaging values in the COVID group when compared to healthy controls. Three significant clusters were found primarily in the white matter regions of the pre-frontal cortex and in the brainstem. The clusters (a) and (b) are observed bilaterally in the cerebral white matter near the orbitofrontal gyrus, whereas (c) lies in the midbrain region.

Figure 1. The fat pad adjacent to the kneecap (Hoffa's fat pad, infrapatellar fat pad) can change in signal on MRI when the knee is inflamed. (A) Normal knee without signs of inflammation. (B) Arrow pointing on a circumscribed area with higher signal (bright lines) in the area of the fat pad (normally dark), which is indicative of a beginning inflammatory reaction. (C) The whole fat pad has a higher signal (light grey color with white lines), which is a sign of progressive inflammation of the knee joint.
