PET/CT is widely used for the evaluation of patients with thoracic malignancies. Although the levels of F-fluorodeoxyglucose (FDG) uptake are usually high in neoplastic diseases, they can also be physiological, due to artifacts. In addition, FDG uptake can occur in benign conditions such as infectious, inflammatory, and iatrogenic lesions. Furthermore, some malignant tumors, such as adenocarcinoma in situ (formerly known as bronchoalveolar carcinoma) and carcinoid tumors, may not show FDG uptake. Here, we illustrate the main pitfalls and artifacts in the interpretation of the results of oncologic PET/CT of the chest, outlining strategies for avoiding misinterpretation.
正电子发射断层显像/计算机断层扫描（PET/CT）被广泛用于评估胸部恶性肿瘤患者。尽管在肿瘤性疾病中氟代脱氧葡萄糖（FDG）摄取水平通常较高，但由于伪影，其摄取也可能是生理性的。此外，FDG摄取可发生于良性情况，如感染性、炎症性和医源性病变。此外，一些恶性肿瘤，如原位腺癌（以前称为细支气管肺泡癌）和类癌肿瘤，可能不显示FDG摄取。在此，我们阐述胸部肿瘤PET/CT结果解读中的主要陷阱和伪影，概述避免误判的策略。
