我们的目的是评估扩散张量成像（DTI）在部分顽固性癫痫患者中的价值。我们使用DTI（25个非共线方向）在15例皮质病变的常规MRI。在内囊和外观正常的白色物质（WM）中测量分数各向异性（FA），邻近病变，并远离病变，设定距离为2-3 cm。在每例患者中，增加或减少的FA测量值是那些使用任意10%阈值的镜像值。在整个人群中，使用Wilcoxon检验比较同侧和对侧FA测量值（p
Our aim was to assess the value of diffusion tensor imaging (DTI) in patients with partial intractable epilepsy. We used DTI (25 noncollinear directions) in 15 patients with a cortical lesion on conventional MRI. Fractional anisotropy (FA) was measured in the internal capsule, and in the normal-appearing white matter (WM), adjacent to the lesion, and away from the lesion, at a set distance of 2-3 cm. In each patient, increased or decreased FA measurements were those that varied from mirror values using an arbitrary 10% threshold. Over the whole population, ipsi- and contralateral FA measurements were also compared using a Wilcoxon test (p
