摘　　要：癫痫是由于大脑神经元异常放电引起的中枢神经系统慢性疾病,影像学检查对癫痫的诊疗具有重要意义,但部分患者在常规磁共振检查中未能发现癫痫病理灶。目前临床上开展的多种影像学后处理技术显著提高了癫痫病理灶的检出率,本文就近年来常用的影像学后处理技术在磁共振阴性局灶性癫痫中的应用做一系统综述。Epilepsy is a chronic neurologic disorder caused by abnormal discharge of neurons in the brain.Imaging examination is of great significance in the diagnosis and treatment of epilepsy,but some patients failed to find any apparent abnormality in conventional magnetic resonance imaging.Recently,a variety of imaging post-processing techniques are applied in clinical practice,which have significantly improved the detection rate of epileptic lesions.In this paper,the research progress of various imaging post-processing techniques in magnetic resonance imaging negative focal epilepsy is reviewed.
