Transient global amnesia (TGA) is a rare and fascinating acute neurological disorder. It is characterized by idiopathic sudden onset anterograde memory loss that resolves within 24 hours of onset and results in no long-term sequelae. The gold standard diagnostic testing for this disorder are clinical criteria. Common emergency department investigations such as bloodwork and computed tomography scans are unremarkable. This paper reviews the yield of diffusion-weighted magnetic resonance imaging (DW-MRI) in the acute setting for the diagnosis of TGA.

短暂性全面失忆症 (TGA) 是一种罕见且令人着迷的急性神经系统疾病。它的特点是特发性突发顺行性记忆丧失，在发病后 24 小时内消退，不会产生长期后遗症。这种疾病的金标准诊断测试是临床标准。常见的急诊科检查，例如血液检查和计算机断层扫描，并没有什么特别之处。本文回顾了弥散加权磁共振成像 (DW-MRI) 在急性期诊断 TGA 的效果。
