动态脑电图监测及MRI对小儿癫痫定位诊断的价值评估

Evaluation of Value of Ambulatory Electroencephalographyand MRI in The Localization Diagnosis of Pediatricepilepsy

目的 探讨动态脑电图监测(AEEG)及磁共振成像(MRI)对小儿癫痫定位珍断的价值。方法 回顾性分析2016年1月至2019年12月间收治的106例小儿癫痫患者临床资料。所有患儿均行AEEG、MRI检查,以术中结果 为癫痫病灶定位“金标准”,评估AEEG、MRI检查对癫痫定位的诊断效能。结果 (1)AEEG检查异常率高于MRI(P<0.05);(2)MRI、AEEG检查小儿癫痫致痫灶总一致率对比差异无统计学意义(P<0.05),MRI定位一致率低于AEEGP<0.(05);(3)AEEG检出异常者84例,放电分布:颡叶29例、额颞15例、枕叶6例、额叶6例、顶叶6例、枕颞叶5倒、额-中央5例、颞中央顶4例、中央-顶2例、顶枕2例;(4)MRI检出异常者59例,病灶分布:颞叶25例、额颞叶7例、枕叶3例、额叶6例、顶叶4例、枕颞叶3例、顶颞叶2例、顶枕1例、基底节区6例。结论 AEEG小儿癫痫异常检出率明显高于MRI,但两者致痫灶定位一致率相近。

Objective To explore the value of ambulatory electroencephalography(AEEG) and magnetic resonance imaging(MRI) in the localization diagnosis of pediatric epilepsy.Methods The clinical data of 106 children patients with epilepsy admitted between January 2016 and December 2019 were retrospectively analyzed.All children patients underwent AEEG and MRI examinations.The intraoperative results were used as the gold standards for epilepsy lesion localization to evaluate the diagnostic efficacy of AEEG and MRI on epilepsy localization.Results(1)The abnormal rate of AEEG examination was higher than that of M RI(P<0.05).(2)There was no statistically significa nt difference in the total consistency rate of epileptogenic foci of pediatricepilepsy between MRI examination and AEEG exa mination(P>0.05),and the localization consistency rate of MRI was lower than that of AEEG(P<0.05).(3)84 cases of abnormalities were detected by AEEG,and their discha rge distribution showed 29 cases of temporal lobe,15 cases of frontotemporal lobe,6 cases of occipital lobe,6 cases of frontal lobe,6 cases of parietal lobe,5 cases of occipital-temporal lobe,5 cases of frontal-central lobe,4 cases of temporalcentral-parietal lobe,2 cases of central-pa rietal lobe and 2 cases of pa rietal-occipital lobe.(4)59 cases of abnormalities were detected by MRI,and the lesion distribution showed 25 cases of tempo ral lobe,7 cases of fro ntotemporal lobe,3 cases of occipital lobe,6 cases of fro ntal lobe,4 cases of parietal lobe,3 cases of occipital-temporal lobe,2 cases of parietal-temporal lobe,1 case of parietal-occipital lobe and6 cases of basal ga nglia area.Conclusion The detection rate of pediatric epilepsy abnormalities of AEEG is significantly higher than that of MRI,but the consistency rate of epileptogenic foci location is similar.
