Focal hyperemia is known to occur in regions of acute cerebral infarction. Presented here are two cases in which SPECT images with 125I-labeled iodoamphetamine demonstrated focal areas of increased tracer concentration associated with cerebral infarction. These results may have important implications regarding the physiology of iodoamphetamine in cerebral infarction and, in particular, whether the distribution of this tracer is related to regional blood flow in this setting. In addition, interpretation of iodoamphetamine images in cerebral infarction should include consideration of this finding.
已知局灶性充血发生在急性脑梗死区域。本文介绍了两例病例，其中用125I标记的碘安非他明的单光子发射计算机断层扫描（SPECT）图像显示与脑梗死相关的示踪剂浓度增加的局灶性区域。这些结果可能对碘安非他明在脑梗死中的生理学具有重要意义，特别是在这种情况下该示踪剂的分布是否与局部血流有关。此外，在脑梗死中对碘安非他明图像的解读应考虑到这一发现。
