【摘要】 目的 :评价磁共振弥散加权成像对急性一氧化碳中毒的诊断价值。方法 :回顾性分析 6例急性一氧化碳中毒的MRI表现 ,分别采用SE序列T1WI、T2 WI、FLAIR和DWI。结果 :急性一氧化碳中毒MRI表现为两侧大脑皮层、皮层下区及苍白球T1WI等信号、T2 WI高信号 ,所有异常信号均呈两侧对称性改变。结论 :磁共振弥散加权成像对急性一氧化碳中毒具有重要诊断价值。更多还原

【Abstract】 Objective:To study the value of diffusion-weighted MR imaging in acute carbon monoxide intoxication.Methods:6 cases of acute carbon monoxide intoxication were performed MR scans by conventional sequences and diffuse weighted sequences.Results:High signal intensity in cerebral cortex and subcortical white matter and globus pallidus were shown on conventional T 2WI,especialy on DWI.Conclusion:Diffusion-weighted MR imaging is an useful imaging method in diagnosis of acute carbon monoxide intoxication.更多还原
