目的：探讨 MR双反转恢复（ DIR）序列在难治性癫痫定位诊断中的价值。分析DIR显示难治性癫痫患者灰质、白质结构的改变。方法：回顾性分析7例难治性癫痫患者的临床、脑电图和影像学资料，观察患者在DIR上的表现。结果：6例复杂部分发作的患者在DIR上发现异常信号，1例全面性发作的癫痫患者在影像学上未发现异常。结论：DIR序列能突出显示灰质和白质结构，灰白质对比度高，对难治性癫痫术前定位诊断具有一定的价值。

Objective:To investigate the imaging feature and diagnostic value of double invesion recov-ery (DIR) MR imaging in intractable epilepsy.Method: The clinical data,EEG and imaging manifestation of 7 cases with intractable epilepsy were retrospectively analyzed on the signal intensity on DIR sequence . Result:Abnormal DIR signal intensities of the DIR images were observed in 6 patients with complex partial seizure , none of abnormal DIR signal intensities of the DIR images was observed in 1 patient with generalized tonic clonic seizure .Conclusion: DIR can show superior delineation of gray matter and white matter .DIR MR imaging can be valuable for characterizing epileptic foci and may contribute to presurgical evaluation in the intractable epilepsy patients .
