Effect of COVID-19 on 18 F-FDG PET/CT: Is There a Need to Consider COVID-19 Status Before Planning 18 F-FDG PET/CT for Oncologic Evaluation?

J Nucl Med Technol. 2021 Sep;49(3):284-285. doi: 10.2967/jnmt.121.262145. Epub 2021 Jul 9.


Incidental detection of coronavirus disease 2019 (COVID-19)-related lung changes on 18F-FDG PET/CT images of oncology patients has been increasingly reported. Most of the case reports or series have stressed the retrospective diagnosis of COVID-19 with the help of 18F-FDG PET/CT lung findings. In this case report, we introduce a different aspect of COVID-19-related lung changes on 18F-FDG PET/CT, interfering with the evaluation of metastatic lung lesions in a patient with renal cell carcinoma.

Keywords: 18F-FDG PET/CT; COVID-19; lung metastasis; renal cell carcinoma; response evaluation.
