摘要
目的:探讨磁共振扩散成像(DWI)对一氧化碳(CO)中毒脑病的诊断价值。方法:CO中毒患者59例,其中迟发脑病15例,均进行DWI检查。结果:59例患者病变区域脑白质平均ADC值为(0.51±0.09)×10-3mm2/s,明显低于正常对照白质ADC值为(0.91±0.07)×10-3mm2/s,前者低于后者(P<0.05)。结论:CO中毒脑病的病变区域脑白质水分子扩散水平明显下降。
Objective: To evaluate the diagnostic significance of MR diffusion weighted imaging (DWI) in encephalopathy after carbon monoxide poisoning. Methods: Fifty-nine patients (15 cases with delayed encephalopathy) with carbon monoxide poisoning underwent DWI examination. The mean ADC value of the frontal cerebral white matter in the lesion area around ventricles was measured and then compared with that in the normal white matter of control group. Results: The mean ADC value of cerebral white matter in the lesion area is significantly lower than in the normal area(0.51±0.09)×10^(-3)mm^2/s vs.(0.91±0.07)×10^(-3)mm^2/s. Conclusion: The diffusivity of cerebral white matter in lesion area declines significantly in delayed encephalopathy after carbon monoxide poisoning.
