OBJECTIVE
To alert the imaging community to potential false positive findings related to current immunization programmes against H1N1 influenza virus.
METHODS
We reviewed 10 patients referred for positron emission tomography/computed tomography (PET/CT) who had undergone recent vaccination.
RESULTS
All studies showed( 18)F-fluorodeoxyglucose (FDG) uptake in the draining axillary lymph nodes close to the vaccination site, while low-dose CT revealed lymph nodes ranged between 0.5 cm and 1.2 cm at the same site.
CONCLUSION
This potential pitfall in PET/CT should be borne in mind during current vaccination programmes.
目的
提醒影像医学界注意与当前针对 H1N1 流感病毒的免疫计划相关的潜在假阳性结果。
方法
我们回顾了 10 例因近期接种疫苗而接受正电子发射断层扫描/计算机断层扫描（PET/CT）检查的患者。
结果
所有研究均显示（18）F-氟脱氧葡萄糖（FDG）在接种部位附近引流的腋窝淋巴结中摄取，而低剂量 CT 显示同一部位的淋巴结大小在 0.5 厘米至 1.2 厘米之间。
结论
在当前的疫苗接种计划中，应注意到这一在 PET/CT 中潜在的陷阱。
