Myocardial perfusion imaging (MPI) with technetium-99m sestamibi (Tc-99m MIBI) is considered a diagnostic technique that is widely used for the investigation of suspected coronary artery disease. Incidental inspection of an extracardiac activity is indirect, but important marker, which can identify a potentially treatable non-coronary cause for chest pain that may mimic cardiac symptoms. Here, we present an illustrative case in which significant enterogastroesophageal reflux of Tc-99m MIBI occurred during the cardiac imaging following prompt hepatobiliary clearance. Because, there was normal myocardial perfusion on MPI, presence of gastroesophageal reflux (GER) on GER scintigraphy and detection of mild inflammation with pathologically confirmed hyperplastic polyp by endoscopy, in view of the above findings we concluded that the probable cause of chest pain was reflux.
使用锝-99m 甲氧基异丁基异腈（Tc-99m MIBI）进行心肌灌注显像（MPI）被认为是一种广泛用于调查疑似冠状动脉疾病的诊断技术。心外活动的偶然检查是一种间接但重要的标志物，它可以识别出可能模拟心脏症状的胸痛的潜在可治疗的非冠状动脉病因。在此，我们展示一个说明性病例，其中在肝胆快速清除后心脏成像期间发生了 Tc-99m MIBI 的显著胃肠食管反流。由于 MPI 显示心肌灌注正常，GER 闪烁显像显示存在胃食管反流（GER），并且内镜检查通过病理证实增生性息肉检测到轻度炎症，鉴于上述发现，我们得出胸痛的可能原因是反流的结论。
