1H MRS imaging (MRSI) was performed on 15 patients with MRI-negative temporal lobe epilepsy (TLE) who underwent seizure surgery. The non-seizure-free patients (NSF) ipsilateral hippocampal N-acetylaspartate (NAA)/(Cr+Cho) z scores were lower than the contralateral scores (p = 0.04), and the NSF ipsilateral z scores were lower than the seizure-free patients' (SF) ipsilateral z scores (p = 0.0049). Similarly, NSF contralateral scores were lower than contralateral SF (p = 0.02). These findings suggest NAA predicts the surgical outcome in patients with TLE without evidence of mesial temporal sclerosis on MRI.
对15例接受癫痫手术的MRI阴性颞叶癫痫(TLE)患者进行了1H磁共振波谱成像(MRSI)。未无癫痫发作的患者(NSF)同侧海马N-乙酰天门冬氨酸(NAA)/(肌酸+胆碱)z评分低于对侧评分(p = 0.04),且NSF同侧z评分低于无癫痫发作患者(SF)的同侧z评分(p = 0.0049)。同样,NSF对侧评分低于对侧SF(p = 0.02)。这些发现表明,NAA可预测MRI上无内侧颞叶硬化证据的TLE患者的手术结果。
