摘要

目的：探讨脑软化灶液体反转恢复序列（FLAIR）高信号与应用磁源性影像（MSI）确定的癫痫灶的位置关系，为癫痫外科手术提供依据。方法：对20例患有脑软化灶的癫痫患者进行了MRI和MSI检查。将MRI所确定的FLAIR高信号与MSI所确定的癫痫灶之间位置关系进行比较。20例患者均行手术治疗。结果：FLAIR高信号位置与MSI所确定的癫痫灶定位完全一致的共12例；部分一致的8例，其中5例MSI所确定的癫痫灶范围小于FLAIR高信号的范围，3例所确定的癫痫灶定位位置范围大于FLAIR高信号区域，按照Engel分级标准，术后（9～59个月）随访19例患者疗效满意。结论：FLAIR高信号与MSI所确定的癫痫灶关系密切，MSI结果对术前制定手术计划有重要意义。

Abstract

Objective: To evaluate the relationship between epileptic focus identified by magnetic source imaging(MSI) and hypertensive signal on fluid attenuated inversion recovery(FLAIR), so as to provide the basis for epilepsy surgery. Methods: MRI and MSI examination were performed in 20 patients with epilepsy and encephalomalacia. Compared the location of the epileptic focus determined by MSI with the location of the hypertensive signal on FLAIR. All 20 patients were operated on. Results: The location of the epileptic focus identified by MSI was all consistent with the location of the hypertensive signal on FLAIR in 12 cases; the epileptic focus identified by MSI was partially consistent with the hypertensive signal on FLAIR in 8 cases, 5 of the 8 patient’s extent of the epileptic focus defined by MSI were smaller than that of the hypertensive signal on FLAIR, the other three were larger than that of the hypertensive signal on FLAIR. Seizure free in 19 cases according to Engel classification of epilepsy. Conclusions: There are obvious correlation between the epileptic focus identified by MSI and the location of the hypertensive signal on FLAIR. The results of MSI might have many values to make the operative plan.
