COVID-19 vaccination has started in most countries, and postvaccination imaging is inevitable in the oncologic population. The immune response to the vaccination in the form of reactive lymphadenopathy has been well documented on 18F-FDG PET/CT. We present the imaging findings of 3 patients who have undergone non-FDG PET/CT imaging including 18F-fluorthanatrace, 68Ga-DOTATATE, and 18F-fluciclovine PET/CT. It is crucial to recognize the timing and laterality of immunization to avoid false-positive findings.
COVID-19 疫苗接种已在大多数国家开始，肿瘤患者接种疫苗后进行影像学检查是不可避免的。18F-FDG PET/CT 已充分记录了疫苗接种引起的免疫反应形式的反应性淋巴结病。我们介绍了 3 名患者的非 FDG PET/CT 成像结果，包括 18F-氟硫乙酸、68Ga-DOTATATE 和 18F-氟仑丁酸 PET/CT。认识到免疫接种的时间和侧别对于避免假阳性结果至关重要。
