We report two cases of transient global amnesia (TGA) diagnosed using a clinical criteria and single photon emission tomography (SPECT) with the aid of Statistical Parametric Mapping (SPM). Both patients underwent an initial SPECT study about 20 h after the disappearance of the amnesic episode, and a second study 3 weeks after the episode. We conducted quantitative cerebral blood flow (CBF) analyses using SPM on Matlab. This revealed regions with abnormal CBF in the first studies but not in the second. This method appears to be useful for diagnosis of TGA, especially in patients with suspected TGA in whom the amnesic episode disappears within a few days.
我们报告了两例使用临床标准并借助统计参数映射（SPM）的单光子发射断层扫描（SPECT）诊断出的短暂性全面性遗忘症（TGA）病例。两名患者在遗忘发作消失后约20小时接受了首次SPECT研究，并在发作后3周进行了第二次研究。我们使用Matlab上的SPM进行了定量脑血流量（CBF）分析。这显示在首次研究中有CBF异常的区域，但在第二次研究中没有。这种方法似乎对TGA诊断有用，特别是对于那些疑似TGA且遗忘发作在几天内消失的患者。
