DWI shows increased signal in cerebellar hemispheres, basal ganglia, and cerebral cortex. These changes are subtle in FLAIR sequence.

- T1WI shows BG hyperintensity and cortical pseudolaminar necrosis
FLAIR shows symmetric hyperintensity in deep gray nuclei and cortex
DWI is less restricted
Case Discussion
In hypoxic ischemic injury DWI is the first imaging sequence to become positive, within hours after HII event. Grey matter is highly vulnerable due to high energy demands.
