Abstract:
It is well-known that vulnerable sites of hypoxic brain damage are the basal ganglia and the periventricular white matters, which are well visualized with CT and conventional MR images. However, there have been several reports about the diffusion of the weighted MR images of hypoxic brain damages. A seventy-nine years old woman and a 61-years old woman were admitted to our hospital due to mental changes, which occurred during sleep as a result of carbon monoxide poisoning. Brain MRIs of the patients showed high signal intensities on the bilateral globus pallidus in both the T2WI and diffusion weighted images. They also revealed high signal intensities on the white matter and bilateral perirolandic cortices in the diffusion-weighted images but not in the T2WI. Therefore, diffusion weighted MR images may be more sensitive to the acute cerebral lesions in hypoxic brain damage than conventional MR images.
