摘要
目的:探讨磁共振脑灰白质成像在脑灰质异位症中的诊断价值。方法:回顾性分析5例经临床及MRI检查确诊的脑灰质异位症患者,全部患者均行脑MRI常规T1WI、T2 WI序列、FLAIR序列和脑灰白质成像检查。结果:5例脑灰质异位症患者在MRI各扫描序列上病灶信号与脑灰质信号完全相同,特别是在脑灰白质成像上对异位的灰质灶观察更为满意,更有利于判断病变的性质。结论:脑灰白质成像在观察灰质异位方面有独到价值,在分析癫痫病因方面可提供更直接的影像学信息。对于脑灰质异位症患者,脑灰白质成像对于帮助发现病灶并判断其性质甚为必要,是对常规序列的必要补充,具有较高的临床应用价值。
Objective： To study the clinical value of MR cerebral grey matter and white matter image in diagnosing gray matter heterotopia. Methods： Five cases of gray matter heterotopia confirmed by clinic and MRI were retrospectively analyzed. All cases were examined with routine T1-weighted, T2-weighted, FLAIR sequences, grey matter and white matter image. Results： The lesions in 5 cases of gray matter heterotopia had similar signals with cerebral grey matter in MRI every sequence. Heterotopic grey matter were satisfactory observed, especially in the grey matter and white matter image. It was more contributive to judge the character of lesions, than other sequence. Conclusion： MR cerebral grey matter and white matter image has unique value in diagnosing gray matter heterotopia. They can supply more immediate image information in analysis etiology of epilepsy. For gray matter heterotopia,it is very essential to find a focus and to judge its character. MR cerebral grey matter and white matter image is a essential complementarity to routine sequences. It has higher application value in clinic.
