Analysis of High Density Area in Brain of Hypoxic Encephalopathy Model Rat Brain Using X-ray CT

Abstract

　Hypoxic Ischemic Encephalopathy (HIE) is a brain disorder. In this research, we developed HIE model rats aiming at examining the functional recovery of HIE by plasma. As a result of evaluation using X-ray CT was confirmed that only the model rats had a high X-ray absorption amount in the brain. In this paper, a region with a high X-ray absorption amount is called a high-density area. Individuals confirmed in the high-density area had cerebral edema and the like which are symptoms of HIE. However, there was a problem that the degree of progress of symptoms could not be judged merely by a high-density area. In this paper, we focused on the luminance value of high density area of HIE model rat and analyzed X - ray CT data. As a result, it was possible to obtain the luminance value distribution of indi-viduals to be control.
