This is a report of a patient who underwent high-resolution brain perfusion SPECT studies during and after an episode of transient global amnesia. During the attack, SPECT imaging showed increased perfusion in the left medial temporal region involving the amygdala and hippocampus. After recovery from amnesia, a follow-up SPECT examination showed slightly decreased perfusion in this region. These findings support the hypothesis that transient global amnesia is associated with transient hyperperfusion in the medial temporal brain structures, and confirm the utility of high-resolution SPECT imaging for the evaluation of the fine details of functional brain anatomy.
这是一份关于一名患者的报告，该患者在短暂性全面性遗忘发作期间及之后接受了高分辨率脑灌注单光子发射计算机断层扫描（SPECT）研究。发作期间，SPECT成像显示左侧内侧颞叶区域（包括杏仁核和海马体）灌注增加。从遗忘症恢复后，后续的SPECT检查显示该区域灌注略有下降。这些发现支持了短暂性全面性遗忘与内侧颞叶脑结构短暂性高灌注相关的假说，并证实了高分辨率SPECT成像在评估脑功能解剖精细细节方面的实用性。
