To investigate the cranial MRI findings in childhood epilepsy and to detect the most frequent cerebral lesions in epileptic children in our region.
In this study, 98 epileptic children were examined with 1 T MRI equipment between January 1997 and March 2001. T1-weighted sagittal, T2 and proton weighted axial and T2-weighted coronal MR images were obtained. Contrast-enhanced T1-weighted axial, sagittal and coronal MR images were also examined in patients with suspicion of infection or intracranial mass.
Among a total of 98 patients, 65 (66.3%) had no pathological findings on MRI. The pathological findings were diffuse cerebral atrophy (18.4%), delay in myelination and dismyelination (12.4%), ischemia and infarct (8.2%), arachnoid cysts (6.2%), tumoral mass (5.1%), mesial temporal sclerosis (1.0%) and sequelae of kernicterus (1.0%).
MRI has been found to be effective in the evaluation of cerebral structures and imaging the pathologies in the etiology of epilepsy and other lesions in childhood focal epilepsy. However, MRI does not always appear to be successful in detecting the epileptic focus.
研究儿童癫痫的头颅磁共振成像（MRI）表现，以发现本地区癫痫患儿最常见的脑部病变。
本研究中，1997年1月至2001年3月期间，98例癫痫患儿接受了1T MRI设备检查。获取了T1加权矢状位、T2加权和质子加权轴位以及T2加权冠状位MR图像。对于怀疑有感染或颅内肿块的患者，还检查了增强T1加权轴位、矢状位和冠状位MR图像。
98例患者中，65例（66.3%）MRI未发现病理改变。病理改变包括弥漫性脑萎缩（18.4%）、髓鞘形成延迟和脱髓鞘（12.4%）、缺血和梗死（8.2%）、蛛网膜囊肿（6.2%）、肿瘤性肿块（5.1%）、内侧颞叶硬化（1.0%）和核黄疸后遗症（1.0%）。
已发现MRI在评估脑结构以及对癫痫病因中的病理改变和儿童局灶性癫痫中的其他病变进行成像方面是有效的。然而，MRI在检测癫痫病灶方面似乎并不总是成功的。
