Images of the hemorrhagic focus in a 22-year-old male patient with diffuse axonal injury caused by a road traffic accident. (A) T1WI: patchy and funicular low-signal-intensity focus (↑) in the white matter of the right frontal lobe and corticomedullary junction. (B) T2WI: this focus displays a patchy and funicular high signal intensity (↑). (C) FLAIR: in addition to the high-signal-intensity focus (↑), we can also detect a spot-like high-signal-intensity focus in the splenium of the right corpus callosum (▲). (D) DWI: a spot-like high-signal-intensity focus in the splenium of the right corpus cal-losum can be detected (▲). (E) T2*WI: spot-like low-signal-intensity foci in the white matter of the right frontal lobe and corticomedullary junction (↑) and in the splenium and genu of the right corpus callosum are detected (▲); (F) SWI: in addition to the foci in the splenium and genu of the right corpus callosum, multiple spot-like low-signal-intensity foci are visible in the body of the right corpus callosum. Multiple spot-like and funicular low-signal-intensity foci are observed in the white matter of the bilateral frontal lobes and corticomedullary junction, and in the periventricular white matter as well. T1WI: T1 weighted image; T2WI: T2 weighted image; FLAIR: fluid-attenuated inversion recovery; DWI: diffusion weighted image; SWI: susceptibility weighted image; R: right; L: left.

Figure 2
Scatterplot of the correlation between the number of hemorrhagic foci detected by SWI and the GCS score. Using Spearman's method, the number of hemorrhagic foci was significantly negatively correlated with GCS score (r = –0.82, P < 0.01). SWI: Susceptibility weighted imaging; GCS: Glasgow Coma Scale; SWI: susceptibility weighted image.
