摘要
对142例癫痫病人进行间歇期SPECT局部脑血流显像,并与脑CT、MRI、EEG、皮质脑电图(ECoG)及手术病理结果进行比较。结果表明,SPECT阳性率最高(75.4%),CT和MRI分别为52.0%和56.7%.SPECT能准确定位癫痫灶,与埋藏式ECoG或术中ECoG标测结果(n=51)的符合率达92.0%。致痫灶的病理改变多为隐匿性脑血管畸形、胶质增生、局灶性神经元固缩、变性及排列紊乱等。研究表明SPECT局部脑血流显像是诊断癫痫病灶的有效方法,灵敏度优于CT和MRI,定位价值优于EEG,对于制订癫痫的手术治疗方案有一定帮助。
Abstract rCBF brain SPECT with 99mTc-ECD was performed on 142 patients with interical epilepsy and was compared with X-ray CT,MRI, electroencephalogram(EEG),electrocorticoencephalogram(ECoG) and pathological findings.with invasive ECoG monitoring or mapping was in concordance with brain SPECT in 46/50(92.0%)patients.The pathological findings of tissue samples commonly involved occult vascular malformation,gliosis or focal neurone lesions.Thereby we concluded that rCBF brain SPECT may haw some advantage in detecting and localizing epileptic foci and it may be also helpful in preparing a reasonable operative protocol for a special epileptic patient.
