| 摘 要： | 摘要] 目的：探讨海马T2弛豫时间（HCT2）在特发性颞叶癫痫（TLE）评价中的价值，并为后续的TLE病例HCT2测量与手术预后相关研究提供基础数据。方法：对36例全面性癫痫（GEP）、23例非颞叶部分性癫痫（NTPE）、26例TLE以及60例正常对照者（CL）进行HCT2测量，并分析其差异。结果：TLE组高侧平均HCT2较CL组增高7.5518ms，较GEP组及NTPE组增高4.1639ms和3.7293ms。TLE组低侧及GEP组和NTPE组低侧、高侧较CL组相应侧别分别增高2.7547ms、3.1347ms、3.2829ms、3.4669ms和3.9016ms。TLE组平均HCT2低/高比率较CL组、GEP组、NTPE组分别降低0.0482、0.0456和0.0425。结论：TLE组病灶侧HCT2明显高于CL组、GEP组及NTPE组，HCT2低/高比率降低是TLE的较特异表现。

| Abstract: | Objective:To determine the value of hippocampal T2 relaxation time(HCT2) on MRI for the assessment of temporal lobe epilepsy(TLE), and provide primary quantitative data to predict its operational prognosis by HCT2.Methods:Thirtysix cases of generalized epilepsy(GEP), 23 non-temporal lobe partial epilepsy(NTPE), 26 temporal lobe epilepsy(TLE) and 60 neurologically healthy people(CL) were chosen to get the HCT2 on oblique coronary MRI obtained by SE dual echo sequence, and the differences of HCT2 between diff... |
