Focal hyperaemia is a fairly common phenomenon in the subacute phase of an ischaemic stroke. This has rarely been reported with iodine-123 iodoamphetamine (IMP) and has never been identified using technetium-99m bicisate (99mTc-ECD). In this report, we present the case of a patient suffering from a left cerebral posterior stroke. 123I-IMP single-photon emission tomography (SPET) images showed a large area of significantly increased IMP activity located in the left occipital region whereas 99mTc-bicisate SPET displayed hypoactivity in the same area.
局灶性充血是缺血性中风亚急性期相当常见的现象。碘-123 碘安非他明（IMP）很少出现这种情况，而锝-99m 双半胱乙酯（99mTc-ECD）从未发现过这种情况。在本报告中，我们介绍了一名左脑后中风患者的病例。123I-IMP 单光子发射断层扫描（SPET）图像显示左枕叶区域有大面积 IMP 活性显著增加，而 99mTc-双半胱乙酯 SPET 显示同一区域活性降低。
