2-[F-18]-fluoro-2-deoxy-D-glucose (FDG) positron emission tomography (PET) has become an important staging modality for many tumors, including bronchial carcinoma; however it is important to know that there are several pitfalls in PET image interpretation. In this report we demonstrate three cases in which focal intrapulmonary FDG uptake could possibly represent iatrogenic microembolism. These FDG accumulations would have been interpreted as malignant tumor mass in the lung if no anatomic correlation would have been performed. For this reason, we further present an integrated PET/CT scanner, which recently has been introduced. This correlation of molecular and morphological information enables the specification of the FDG-PET findings.
2-[F-18]-氟-2-脱氧-D-葡萄糖（FDG）正电子发射断层扫描（PET）已成为包括支气管癌在内的许多肿瘤的重要分期手段；然而，了解PET图像解读中存在一些陷阱很重要。在本报告中，我们展示了三例局灶性肺内FDG摄取可能代表医源性微栓塞的病例。如果未进行解剖学关联，这些FDG聚集可能会被解读为肺部恶性肿瘤肿块。因此，我们进一步介绍了最近推出的一体化PET/CT扫描仪。分子信息与形态学信息的这种关联能够明确FDG-PET检查结果。
