| 摘 要： | 目的：探讨单光子断层扫描（SPECT）对颅内非局灶性病变致癫痫的无创性定位诊断的作用和临床意义，并与EEG，MRI进行比较，方法：对88例癫痫病人分别在1－2周内行SPECT，EEG，MRI检查，比较3种方法的检出率，准确度，特异度，敏感度，阳性及阴性预测值，结果：SPECT的检出率，准确率，敏感度，阴性预测值显著高于MRI（P＜0．05），其特异度显著低于MRI（P＜0．05），SPECT的检出率，准确度，特异度，敏感度，阳性及阴性预测值与EEG比较，均无显著性差异（P＞0．05），结论：SPECT检查在癫痫定位中优于MRI，其对单一癫痫灶的检出亦优于EEG。

| Abstract: | Objective:To evaluate the value of Spect rCBF imaging in locating of epileptic diseases which are caused by non-local pathological changes and its clinical significance.It was compared with EEG and MRI.Methods: SPECT,EEG and MRI were performed in all patients in 1~2 weeks. The positive rate, the sensitivity and the accuracy etc were compared in them.Results:The positive rate,the accuracy,the sensitivity and forecast of Spect rCBF are higher than MRI(P<0.05).Its positive forecast is lower than MRI(P<0.05).There is no remarkable difference between SPECT and EEG(P>0.05). Conclusion: Spect rCBF has remarkable superiority to MRI in epilepsy foci, It is also better than EEG in locating single epilepsy foci. |
