目的:研究海马硬化患者的MRI表现。方法:应用GE 1.5THorizon LX超导MR机及Siemens 3.0TMR机对15例病人进行多序列扫描,并对获得图象进行分析。结果:海马硬化的MRI表现有:(1)海马结构萎缩;(2)T2加权像上海马结构的高信号;(3)颞叶前部萎缩;(4)颞角扩大。结论:MRI是检测海马硬化的首选方法。
Objective: To study the MRI findings of hippocampal sclerosis patients. Methods: Fifteen patients were scanned by GE 1.5THorizon LX superconducting MR machine and Siemens 3.0TMR machine, and the obtained images were analyzed. RESULTS: MRI findings of hippocampal sclerosis were as follows: (1) atrophy of the hippocampus; (2) hyperintensities of the hippocampal formation on T2 weighted images; (3) atrophy of the anterior temporal lobe; and (4) expansion of the temporal angle. Conclusion: MRI is the preferred method of detecting hippocampal sclerosis.
