Morphological and Metabolic Criteria of COVID-19 Vaccine Associated Axillary Nodes on 18-Fluorodeouxyglucose PET/CT Imaging in Breast Cancer Patients

CONCLUSION: In COVID-19 vaccinated patients with BC, 18FDG avid nodes in VSA may pose diagnostic challenge. However, morphological (size < 10 mm short axis, intact fatty hila without fat stranding) and metabolic criteria (SUVmax <2.4 with negative correlation with time of inoculation) have higher diagnostic accuracy in resolving the dilemma. Nodes in VSA having SUVmax > 2 SD of hepatic SUVmax should be considered for FNA to rule out possible metastasis.PMID:38156837 | DOI:10.31557/APJCP.2023.24.12.4053
