Abstract

We present a rare case of focal F-18-2-fluoro-2-deoxyglucose (FDG) uptake in the liver observed during a modified dual-time-point F-18 FDG positron emission tomography (PET)/computed tomography (CT), so-called early delayed scanning, in a 53-year-old woman diagnosed with breast cancer. This metastatic lesion was revealed in 80 min delayed images after FDG injection, but not in the usual one-hour images after injection. Modified dual-time-point F-18 FDG PET/CT is convenient because compared to the 2 h delayed images of dual-time-point PET/CT, it has a shorter scanning time and avoids additional radiation exposure.

摘要

我们介绍了在改良的双时间点F-18FDG正电子发射断层扫描（PET）/计算机断层扫描（CT）期间观察到的肝脏局灶性F-18-2-氟-2-脱氧葡萄糖（FDG）摄取的罕见病例，所谓的早期延迟扫描，一名53岁的女性被诊断患有乳腺癌。在FDG注射后80分钟的延迟图像中发现了这种转移灶，但不是在注射后通常的一小时图像中。改进的双时间点F-18FDGPET/CT是方便的，因为与双时间点PET/CT的2h延迟图像相比，它具有较短的扫描时间和避免额外的辐射暴露。
