Abstract
Quantitative computed tomography (QCT) and histopathology were used to assess the effects of large single doses of x irradiation on the normal canine brain. Measurable changes demonstrated by QCT included increased contrast enhancement and enlargement of the lateral ventricles, which were observed prior to any clinical signs. The results suggest that QCT methods are effective in the noninvasive evaluation of radiation-induced brain injury.
摘要
定量计算机断层扫描（QCT）和组织病理学被用于评估大剂量单次X射线照射对正常犬脑的影响。QCT显示的可测量变化包括对比增强增加和侧脑室扩大，这些变化在出现任何临床症状之前就已观察到。结果表明，QCT方法在无创评估辐射性脑损伤方面是有效的。
