We report a three-year-old boy with Reye syndrome evaluated by 99mTc-ECD SPECT. On acute stage, 99mTc-ECD brain SPECT disclosed diffuse high uptake in the cerebral cortex in spite of normal findings on brain X-ray CT. These lesions changed to general low uptake on the chronic state and multiple high intensity areas were shown on T2 weighted MRI image. Such a change of cerebral tracer uptake was considered to reflect the neuropathological change of Reye syndrome. 99mTc-ECD SPECT was a useful modality to diagnose Reye syndrome complementary.
我们报告了一名通过99mTc-ECD单光子发射计算机断层扫描（SPECT）评估的患有瑞氏综合征的三岁男孩。在急性期，尽管脑部X线计算机断层扫描（CT）结果正常，但99mTc-ECD脑SPECT显示大脑皮质弥漫性高摄取。这些病变在慢性期变为普遍低摄取，并且在T2加权磁共振成像（MRI）图像上显示出多个高强度区域。脑示踪剂摄取的这种变化被认为反映了瑞氏综合征的神经病理变化。99mTc-ECD SPECT是一种有助于补充诊断瑞氏综合征的有用方法。
