FIG 3. A 45-year-old woman (group 2) with PRES.

A, Axial T2-weighted image shows bilateral abnormal hyperintense signal intensity in the occipital subcortical white matter and in the posterior limb of the internal capsule.

B, Corresponding axial FLAIR image shows the hyperintense abnormalities more clearly.

C, On axial ADC map corresponding to A and B increased signal intensity of the abnormalities is seen, consistent with increased diffusion, which is indicative of vasogenic edema.
