海马硬化的MRI研究

MRI of Hippocampal Sclerosis

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.Methods Fivteen refractory hippocampal sclerosis were studied with GE 1.5T Horizon LX MR scanners and Siemens 3.0T MR scanners,and acquried all kinds of images.Results By visual estimation,the main findings of hippocampal sclerosis patients on MR images were :(1) atrophy of hippocampal formations;(2) high signal intensity of hippocampal formations;(3) atrophy of anterior temporal lobe;(4) dilatation of temporal horn.Conclusion MRI was the first ch...
