摘　　要：目的比较外伤性癫痫患者CT、MRI与脑电描记术(EEG)及经颅多普勒(TCD)的检查结果。方法65例外伤性癫痫患者分别行CT、MRI及EEG、TCD检查,并对各种检测的结果进行比较。结果EEG对外伤性癫痫病灶的检出阳性率最高,为78%(51/65),CT为42%(27/65),MRI为54%(27/50),TCD为62%(40/62);病灶的定位率以MRI最高,为96%(26/27),CT为89%(24/27),EEG为57%(29/51)。CT及MRI与EEG检出的病灶部位符合率分别为52%(14/27)和63%(17/27)。结论四种方法各有其优势,也有其不足,它们相互结合可以提高外伤性癫痫的正确诊断及病灶定位率。Objective To compare the results of CT, MRI, electroencephalogram （EEG） and transcranial Doppler （TCD） in examination of posttraumatic epilepsy. Methods A total of 65 cases of posttraumatic epilepsy were checked by CT, MRI, EEG and TCD respectively and a comparison done on all results. Results The positive rates of EEG, CT, MRI and TCD were 78% （51/56） , 42%（27/65） , 54% （27/50） and 62% （40/62） respectively, where EEG ranked the first place. The locating rate of MRI was 96% （26/27）, higher than that of CT （89% ,24/27） and EEG （57% ,29/51 ）.The epileptic focus for 52% （14/27） localized by CT and that for 63% （17/27） localized by MRI were in concordance with EEG. Conclusion Each of the four methods has its own advantage and insufficiency, but the combination of four methods is helpful for more accurately detecting and localizing epileptic focus.
