Excerpt
Messenger RNA (mRNA) COVID-19 vaccine is one of the main vaccine types currently used for preventing SARS-CoV-2 infection worldwide. However, its administration can interfere with an FDG PET study since an increased uptake of 18F-FDG can be observed at the vaccine injection site and adjacent regional lymph nodes. The interpretation of PET study in oncologic patients might be impacted especially in head and neck cancer, breast cancer or lymphoma in which supraclavicular and axillary lymph node metastases are suspected. Hence, Advani et al. [
1] suggest that FDG PET study should be performed at least 2 weeks after vaccination to reduce the interference of lymphadenopathy causing by vaccination in PET interpretation. …
