急性一氧化碳中毒的临床表现与MRI分析

MR imaging of acute carbon monoxide poisoning

目的 评价MRI对急性CO中毒的诊断价值。方法 分析 5 9例经临床确诊的急性CO中毒患者的头颅MRI资料。结果 MRI异常表现为苍白球变性坏死 ,双侧大脑白质区脑水肿 ,以脑室周围为主的长T 1长T2信号 ,后期出现脑萎缩征象 ,海马区及脑干的改变。结论 本病的诊断主要依靠病史、临床表现和影像检查 ,头颅MRI对本病的诊断。

Objective To assess the diagnostic value of MRI in acute carbon monoxide poisoning. Methods The clinical and MRI data of 59 patients with acute carbon monoxide poisoning were analysed. Results The MRI showed the necroses and degeneration of flobus pallidus, edema of bilateral cerebral white matter with prolonged T1 and T2 signals within periventricular regions and with subsequent cerebral atrophy and hippocampus changes. Conclusion The diagnosis of acute carbon monoxide poisoning mainly depends on case history, clinical features and neuroradiological presence. MRI is very valuable in the diagnosis and the prognosis.
