摘　　要：目的综合分析磁共振成像(magnetic resonance imaging,MRI)在难治性癫痫致痫病灶定位中的应用及诊断价值。方法回顾性分析2014年8月至2016年11月本院收治的123例难治性癫痫患者的临床资料,按照入院先后顺序将其随机分为脑电图(electroencephalogram,EEG)组、正电子发射断层计算机扫描(positron emission tomography-computed tomography,PET-CT)组、MRI组,每组各41例。比较三组患者的阳性诊断率和病灶准确定位率。结果 MRI组患者阳性诊断率显著高于EEG组和PET-CT组(P<0.05),PET-CT组患者阴性诊断率显著高于MRI组和EEG组(P<0.05)。MRI组病灶准确定位率显著高于EEG组和PET-CT组(P<0.05)。结论 MRI在难治性癫痫致痫病灶定位中的应用及诊断价值显著高于EEG和PET-CT。Objective To analyze the application and diagnostic value of magnetic resonance imaging（MRI） in the localization of epileptiform lesions in patients with intractable epilepsy. Method The clinical data of 123 patients with intractable epilepsy treated in our hospital from August 2014 to November 2016 were retrospectively analyzed. All patients were randomly divided into electroencephalogram（EEG） group, positron emission tomography-computed tomography（PET-CT） group and MRI group, 41 patients in each group. The positive diagnosis rate and accurate location rate of lesions among the three groups were compared. Result The positive diagnosis rate of MRI group was significantly higher than PET-CT group and EEG group（P〈0.05）. The negative diagnosis rate of PET-CT group was significantly higher than MRI group and EEG group（P〈0.05）. The accurate location rate of lesions in MRI group was significantly higher than EEG group and PET-CT group（P〈0.05）. Conclusion The application and diagnostic value of MRI in the localization of epileptic lesions in patients with intractable epilepsy is significantly higher than that of EEG and PET-CT.
