摘　　要：目的探讨扩散张量成像,(diffusion tensor imaging,DTI)与常规头颅MRI对一氧化碳中毒后迟发脑病价值。方法收集一氧化碳中毒后迟发脑病患者21例为患病组,与患病组性别年龄匹配健康志愿者21例为对照组,所有受试者行常规头颅MRI和DTI检查。结果双侧放射冠、半卵圆中心云雾状长T1、长T_2信号,双侧苍白球区对称分布长T1、长T_2信号。患病组白质FA值较对照组下降。结论扩散张量成像联合常规头颅MRI对一氧化碳中毒后迟发脑病有重要价值。Objective To explore the value of diffusion tensor imaging and conventional head MRI in delayed encephalopathy after carbon monoxide poisoning.Methods to collect carbon monoxide poisoning after delayed encephalopathy patients 21 cases for the prevalence of group,and illness age sex group matching healthy volunteers 21 cases as control group.All the subjects underwent routine CT and MRI and DTI.Results bilateral corona radiata,semi oval center cloud like long T1,long T2 signal,bilateral pale white ball symmetric distribution,long T1 and long T2 signal.The FA value of white matter in the diseased group was lower than that in the control group.Conclusion diffusion tensor imaging combined with conventional MRI scan is of important value in delayed encephalopathy after acute carbon monoxide poisoning.
