  • Look Inside

DWI (Diffusion-weighted images) of the brain has been revealed to be useful in diagnosis of several clini-cal conditions. However, little is known about DWI with regard to brain death. We had opportunities to study patients with brain death.

Case 1. A 34-year-old woman experienced cardio-pulmonary arrest due to severe ventricular fibrillation, and resuscitated after about 120 minutes. After brain death, DWI showed high signals in the cerebral cor-tex, putamen, thalamus, brain stem and cerebellum, and ADC (apparent diffusion coefficient) values were 30~40% lower than those of normal volunteers.
