脑弥漫性轴索损伤32例影像学诊断分析

Thirty Two Patients with Diffuse Axonal Injury:Analysis of Imaging Diagnosis

目的 通过对脑弥漫性轴索损伤 (DAI)临床、CT及MRI的影像学表现的分析 ,以期提高对DAI的诊断水平。方法 分析有完整临床资料 ,同时进行过CT和MRI检查 ,特别是CT检查相对阴性的 32例DAI患者的影像学诊断结果。结果 32例DAI患者CT检查相对阴性 ,MRI检查发现在胼胝体、基底节、脑干及灰白质交界处多发小的异常信号灶。结论 临床拟诊DAI的患者在CT检查相对阴性时可进行MRI检查 。

Objective To study clinic and image features of DAI to improve the diagnosis of DAI.Methods Thirty two patients with DAI have full clinic materials and examinations of CT、MRI,specially with relatively negative CT findings.Results Thirty two pitients with relatively negative CT findings have mutiplied small abnormal lesions in the corpus callosum、basal ganglia、brainstem and conjunction of gray and white matter in MRI.Conclusion DAI-suspected patients with relatively negative CT findings may have MRI examination and the image features of MRI is helpful to diagnosis of DAI.
