对19例癫痫患者行垂直于海马长轴的斜冠状液体衰减反转恢复序列(FLAIR)和T1WI、T2WI成像。结果19例手术病理证实均为海马硬化。其中左侧海马硬化11例,右侧海马硬化8例。19例患侧海马均有萎缩性改变,并且在T2WI和FLAIR成像呈高信号,17例患侧海马头部浅沟明显消失。认为海马体积缩小、信号增高及海马头部浅沟消失是海马硬化的特征性MRI表现,可为临床医生提供精确的定位和定性诊断。
Twenty-nine patients with epilepsy underwent oblique coronary fluid attenuation inversion recovery sequence (FLAIR) and T1WI and T2WI imaging perpendicular to the major axis of the hippocampus. Results 19 cases of surgical pathology confirmed hippocampal sclerosis. Including left hippocampal sclerosis in 11 cases, right hippocampal sclerosis in 8 cases. All 19 patients had atrophic changes in the affected side of the hippocampus, and showed high signal on T2WI and FLAIR imaging. That the hippocampus volume reduction, increased signal and the disappearance of shallow grooves in the hippocampus is a characteristic MRI of hippocampal sclerosis, which can provide accurate positioning and qualitative diagnosis for clinicians.
