摘要
目的:在急性脑外伤患者的CT片研究脑弥漫性轴索损伤(DAI)的CT征象,目的是为DAI的诊断提供影像学依据。材料与方法:回顾性分析经临床确诊的40例DAI患者的早期CT表现,结合文献提出DAI的CT诊断标准:脑白质内单发或多发无占位效应的小出血灶(直径小于2cm),中线结构无移位;蛛网膜下腔出血(SAH)或脑池内出血;脑室内出血;弥漫性脑肿胀。结果:40例DAI早期CT表现:脑白质内单发或多发小出血灶(大脑半球18例,基底节区3例,胼胝体2例,丘脑区1例),SAH或/和脑地内出血16例,脑室内出血9例,弥漫性脑肿胀40例。结论:作者认为,上述CT诊断标准与临床DAI患者的早期CT表现相符,为临床诊断DAI提供可靠依据。
The purpose of this aticle is to study the CT signs in diffuse axonal injury(DAI)of acute brain injury.Materials and Methods:CT signs of 40 cases of DAI confirmed clinically were reviewed.The criterion of CT diagnosis consists:Of the presence one or more hemorrhagic lesions(less than 2cm in diameter)at white matter without space occupying effect,and no middle line structure deviation;subarachnoid hemorrhage(SAH)or intracerebral cisterna hemorrhage.intraventricular hemorrhage and acute diffuse brain swelling.Results:CT scans of 40 cases with DAI of early phase showed one or more small hemorrhage lesions less than 2cm in diameter at cerebralhemisphere 18 cases, basal nuclei 3,copus collosum 2,thalamus 1,SAH and/or intracerebral cisterna hemorrhage 16 and intraventricular hemorrhage 9.All cases showed acute brain swelling.Conclusion:It is believed that the criterion of DAI in CT imaging were corresponded to that of in clinic. CT can provide reliable evidence for clinical diagnosis of DAI.
