| 摘 要： | 目的 :阐述慢性海洛因成瘾者脑部的核磁共振成像 (MRI)表现及其诊断价值。方法 :本组 ( 6例 )均进行MRI检查 ,其序列包括T1WI、T2WI和FLAIR。结果 :本组幕上半球脑白质、小脑半球、内囊后肢及膝部、胼胝体压部及膝部均见双侧、对称性异常改变。MRI均表现为T1WI呈低信号 ,T2WI及FLAIR序列为不均匀或均匀高信号。结论 :慢性海洛因成瘾者所致脑白质病具有典型的MRI表现。MRI对海洛因成瘾机制的研究有较好的应用前景。

| Abstract: | Objective: To evaluate MRI diagnosis on the chronic heroin addictive brain. Methods:T1WI,T2WI and FLAIR sequences were performed in 6 patients with chronic heroin addictive history.MRI findings were analyzed. Results: In all the patients,bilateral and symmetrical lesions were seen in the cerebral and cerebellar white matter,in the intemal capsule and callosum.These lesions displayed hypointensity on T1WI,while hyperintensity on T2WI and FLAIR. Conclusion: Heroin induced leukoencephalopathy has some characteristics on MRI,which may be very helpful for the diagnosis of chronic heroin addictive brain. |
