液体衰减反转恢复(fluid-attenuated inversion recov- ery,FLAIR)技术由Ha jnal等等1992年首次报告并应用于临床。随着影像技术的发展,FLAIR技术也不断完善, 表现为成像时间越来越短,影像质量不断提高。因此其应用也更加广泛。本文通过对颞叶癫痫病人SE序列T2WI和 Fast FLAIR序列成像中海马信号的比较,探讨FLAIR序列在诊断海马硬化中的价值。 1 材料和方法临床及脑电图诊断为颞叶癫痫患者27例,其中男11 例,女16例,年龄13-59岁,平均33.5岁,病史最短者 6个月,最长者23年,其中4例患者儿童期有高热、惊厥史。 Fluid-attenuated inversion recov- ery (FLAIR) was first reported by Hajnal et al in 1992 and has been used clinically. With the development of imaging technology, FLAIR technology has been continuously improved, showing the imaging time is getting shorter and shorter, image quality continues to improve. So its application is more extensive. In this paper, we compared the hippocampal signals in imaging of SE sequence T2WI and Fast FLAIR in patients with temporal lobe epilepsy to explore the value of FLAIR in the diagnosis of hippocampal sclerosis. 1 Materials and Methods Clinical and EEG diagnosis of temporal lobe epilepsy in 27 patients, including 11 males and 16 females, aged 13-59 years, mean 33.5 years, the shortest history of 6 months, the longest 23-year, Four of these patients had a history of high fever and convulsions in childhood.
