DWI对二氯乙烷中毒性脑病的诊断价值(附7例报告)

目的:探讨二氯乙垸中毒性脑病的DWI表现.方法:对7例二氯乙烷中毒性脑病患者行头颅常规MRI 及DWI检查,并测量病灶的ADC值.结果:7例均可见双侧额颞枕顶叶皮质下及白质、小脑齿状核、豆状核、丘脑、外囊和内囊等区域异常信号,常规MRI上呈长T1、长T2信号,DWI上呈高信号.轻症患者(5例)ADC图上病灶呈高信号,重...

DWI fealures of brain with toxic encephalopathy induced by 1, 2-DCE (with report of seven cases)

Objective：To investigate the values of diffusion weighted imaging（DWI） in patients with 1,2-dichloroe-thane（1,2-DCE） encephalopathy.Methods：Seven patients suffered from toxic encephalopathy caused by 1,2-DCE were examined by routine cranial MRI and DWI.ADC values were calculated by workstation in time.Reuslts：The signals abnormalities were detected in the patients′ subcortex and white matter of the bilateral frontal,temporal,parietal and occipital lobes,cerebellar dentate nucleus,lenticular nucleus,thalamus,external capsule and internal capsule.They showed long T1 and T2 signals on routine MRI,high signals on DWI images.On ADC map delivered from DWI,they showed high intensity in slight cases and low intensity in moderate and severe cases.Conclusion：1,2-DCE encephalopathy has typical imaging characteristics on MRI.DWI may provide references for severity of pathological changes and prognosis of 1,2-DCE encephalopathy.
