| 中文摘要: |
| 目的探讨海洛因脑病的MRI表现。方法 回顾性分析22例有海洛因吸食史患者的MRI资料,检查序列包括T1WI、T2WI及FLAIR序列。结果 2例患者MRI表现未见异常,其余20例患者幕上或(及)幕下脑实质有不同程度的受累, 17例有灰质受累, 病变双侧对称,均表现为T1WI低信号,T2WI及FLAIR序列高信号,2例有轻度占位效应,1例轻度脑萎缩。结论 海洛因所致脑病既可侵犯白质也可侵犯灰质,称之为海洛因脑病更恰当;海洛因脑病具有典型的MRI表现,结合临床病史可与其他脑病鉴别。 |

| Objective To clarify MRI characteristics of heroin encephalopathy. Methods T1WI, T2WI and FLAIR sequences were performed in 22 patients with heroin addiction history, and MRI findings were analyzed. Results Of the 22 cases, lesions were seen in various degrees in the brain both over and under the tentorium in 20 cases in MRI, and the gray matter was invaded in 17 cases. Two cases were demenstrated negative. These lesions displayed bilaterally and symmetrically, showing hypointensity on T1WI and hyperintensity on T2WI and FLAIR. Slight mass effects were seen in 2 cases, and slight brain shrinkage was seen in 1 case. Conclusion In encephalopathy induced by heroin, both the white matter and the gray matter were invaded, therefore, "heroin encephalopathy" is the suggested name of this disease. Heroin encephalopathy has some typical characteristics on MRI, which are very helpful for differential diagnosis in combination with heroin addiction history. |
