目的 探讨磁共振成像 (MRI)对难治性癫痫患者病因诊断的价值及其对治疗的指导作用。方法 分析 2 12例难治性癫痫患者的临床和MRI资料。结果 (1) 2 12例难治性癫痫患者中 ,118例MRI有改变 ,异常发现阳性率为 5 5 .7% (118/ 2 12 ) ,揭示的病因共 7种 ,其中以脑软化、脑发育异常多见 ;(2 )不同发作类型的MRI改变阳性率不同 ;(3)不同发作类型的MRI改变所揭示的病因不同 ;(4 )不同年龄组难治性癫痫患者MRI改变所揭示的病因不同。结论 头颅MRI扫描对难治性癫痫的病因诊断有重要意义 ,可为难治性癫痫确定治疗方向和选择治疗方法提供可靠依据 ,对判断难治性癫痫的预后有一定的指导意义。
Objective To investigate the value of magnetic resonance imaging (MRI) in the diagnosis of refractory epilepsy and its guiding role in the treatment. Methods Clinical and MRI data of 2 12 patients with refractory epilepsy were analyzed. Results (1) Of the 12 cases of refractory epilepsy, 118 cases had MRI changes, and the positive rate was 75.7% (118/212). There were 7 etiologies revealed in this study. Among them, (2) The positive rates of MRI changes in different seizure types are different; (3) The etiology revealed by MRI changes of different seizure types is different; (4) The etiology of MRI revealed in patients with refractory epilepsy of different age groups different. Conclusion The cranial MRI scan is of great significance in the etiological diagnosis of refractory epilepsy. It can provide a reliable basis for the treatment of refractory epilepsy and the selection of treatment methods. It is of guiding significance in judging the prognosis of refractory epilepsy.
