Figure 1.

A 27-year-old female experienced sudden cardiac arrest in which her blood pressure decreased to non-palpable for 10 min. Diffusion-weighted image (a) shows high signal intensity areas in the cortical border zone between the right middle cerebral and posterior cerebral arteries, suggesting watershed infarcts (arrow). The apparent diffusion coefficient map (not shown) confirmed restricted diffusion in the corresponding area. There are also several small watershed infarcts in the cerebellar cortical regions bilaterally on the diffusion-weighted image (b).
