对127例癫痫儿童于癫痫发作间歇期进行单光子发射计算机断层(SPECT)脑血流显像,并与脑电图(EEG)、脑CT和MRI检查进行比较。结果表明,SPECT脑血流显像阳性率高达82.7％,EEG、脑CT和MRI的阳性率分别为50.4％,18.4％和32.1％。EEG出现异常时,SPECT脑血流显像常亦有异常,二者定位结果的一致及相对一致率为78.1％(25/32)。脑CT出现局灶性异常时,SPECT脑血流显像亦会有相应部位的异常。说明SPECT脑血流显像在癫痫灶的检出和定位诊断上有一定价值。
One hundred and fourteen children with epilepsy underwent single photon emission computed tomography (SPECT) cerebral perfusion imaging during the seizure interval and compared with EEG, brain CT and MRI. The results showed that the positive rate of SPECT cerebral blood flow imaging was 82.7%, the positive rates of EEG, CT and MRI were 50.4%, 18.4% and 32.1% respectively. EEG abnormalities, SPECT cerebral perfusion imaging often also have abnormalities, the positioning of the two consistent and the relative consistency rate was 78.1% (25/32). Focal cerebral CT appears abnormal, SPECT cerebral blood flow imaging will also have the corresponding parts of the anomaly. Description of SPECT cerebral blood flow imaging in the detection and localization of epileptic foci have some value.
