磁共振成像在肝性脑病诊断及评价临床转归中的价值

The value of MRI in the diagnosis of hepatic encephalopathy and the evaluation of clinical prognosis

目的:探讨磁共振成像(MRI)在肝性脑病诊断及评价临床转归中的价值。方法:选择临床明确诊断的肝性脑病16例,进行常规MRI扫描及3个月后复查,总结MRI特征性表现,将MRI信号变化与其临床转归进行相关性研究。结果:16例患者MRI检查T1WI序列均可见双侧基底节区对称性分布的T1WI高信号,MRI异常信号变化与其临床转归有较高的一致性,主要表现在信号强度及异常信号范围变化上。结论:肝性脑病患者在MRI检查中存在特征性表现,并在一定程度上反映病情转归。

Objective：To investigate the value of MRI in the diagnosis of hepatic encephalopathy and the evaluation of clinical prognosis.Methods：16 patients with hepatic encephalopathy proven by clinical examinations were enrolled in the study,conventional brain MRI examination was performed.All of them were followed up at 3 months.Summed up MRI characteristic features,studied the association between the change of MRI signals and the clinical prognosis.Results：The symmetrical hyperintensity in both sides of basal ganglia on T1-weighted MRI was found in all 16 patients.There was a significant correlation between the change of MRI signals and the clinical prognosis,mainly in the change of abnormal signal intensity and signal range.Conclusion：Patients with hepatic encephalopathy had characteristic features in MRI examination,and to some extent reflected the disease prognosis.
