Three hundred twenty-one separate acquisition dual-isotope myocardial perfusion scans were reviewed retrospectively. Studies performed in six patients demonstrated a relative improvement in Tc-99m sestamibi uptake during stress in segments that appeared abnormal on rest injected Tl-201 images. All patients who demonstrated this pattern had a prior history of myocardial infarction and interventional revascularization. While many factors may contribute to this appearance, the authors favor the presence of a patent infarct-related artery as being the most significant.
对321例独立采集的双同位素心肌灌注扫描进行了回顾性分析。在6例患者中进行的研究表明，在静息注射铊-201图像上显示异常的节段，在负荷状态下锝-99m甲氧基异丁基异腈摄取有相对改善。所有表现出这种模式的患者都有心肌梗死和介入性血运重建的既往史。虽然许多因素可能导致这种表现，但作者认为存在梗死相关动脉通畅是最重要的因素。
