Abstract

It is estimated that in excess of one million positron emission tomography (PET) scans are performed each year and PET can now truly be regarded as a routine imaging procedure in clinical management. Many potential pitfalls and artifacts have previously been described with (18)F-fluorodeoxyglucose PET imaging, but more continue to become apparent as worldwide experience increases. In addition, the advent of combined PET/CT scanners in clinical imaging practice has brought their own specific pitfalls and artifacts. It is essential that we learn these potential pitfalls so that patients can be optimally prepared for their scans and that accurate interpretation can be made.

摘要

据估计，每年进行的正电子发射断层扫描（PET）超过100万例，如今PET在临床管理中已真正可被视为一种常规成像检查。之前已有许多关于（18）F-氟脱氧葡萄糖PET成像的潜在陷阱和伪影的描述，但随着全球经验的增加，更多的此类情况不断显现出来。此外，PET/CT联合扫描仪在临床成像实践中的出现也带来了其特有的陷阱和伪影。我们必须了解这些潜在的陷阱，以便能让患者为扫描做好最佳准备，并能进行准确解读。
