Brain single photon emission computed tomography (SPECT) with 99mTc-d,l-hexamethyl-propyleneamine oxime (HMPAO) was performed twice in a 78-year-old man clinically diagnosed as brain death according to the standard criteria of the Japanese Ministry of Welfare. The first brain SPECT demonstrated the tracer accumulation in the brain, indicating preserved cerebral blood flow. The second brain SPECT performed 3 days later revealed cessation of the blood flow. In patients with preserved cerebral blood flow, the diagnosis of brain death cannot be made, even if they meet the existing criteria, because previous report noted the recovery in some of those patients. Brain perfusion SPECT plays an important role as a confirmatory test for the diagnosis of the brain death.
对一名78岁男性进行了两次脑单光子发射计算机断层扫描（SPECT），该患者根据日本厚生省的标准被临床诊断为脑死亡。第一次脑SPECT显示示踪剂在脑内蓄积，表明脑血流保留。3天后进行的第二次脑SPECT显示血流停止。在脑血流保留的患者中，即使符合现有标准也不能诊断为脑死亡，因为之前的报告指出其中一些患者有恢复情况。脑灌注SPECT作为脑死亡诊断的确认性检查发挥着重要作用。
