| 摘 要： | 目的:分析总结肝性脑病患者脑MRI的信号特点。方法:应用Toshiba VISART 1.5T磁共振扫描仪对18例慢性肝病患者行颅脑T1WI、T2WI扫描,部分病例行FE序列成像。结果:18例慢性肝病患者颅脑MR成像阳性者12例。肝性脑病患者脑MRI检查可出现双侧对称性分布的基底节(主要是苍白球)、大脑脚异常信号,T1WI为高信号,T2WI为等或高信号,FE序列为黑色信号。结论:MRI能够反应肝性脑病的信号特点,为临床提供重要信息。

| Abstract: | Objective: To analyze and summarize the cerebral MRI signal characteristics of hepatic encephalopathy. Methods: Cerebral MRI in 18 patients with chronic hepatic disease were performed with T1WI- T2WI and field-echo imaging. Results: Twelve of the 18 patients presented hyperintense signal in bilateral basal ganglion(globus pallidus) and midbrain on T1WI- iso- or hyper-intense signal on T2WI- and low signal in FE sequence. Conclusions: MRI can reflect the signal feature of the hepatic encephalopathy- provide important clinical information. |
