摘要 PET/CT在临床上得到了广泛的应用和肯定,但是PET/CT图像同样存在一些伪影并且这些伪影很有可能影响医师的诊断。本文从4个方面对PET/CT伪影进行阐述,从原理和技术层面分析了伪影的成因,总结了目前解决伪影的一些方法。 PET/CT imaging is widely used clinically, however, there are some artifacts in PET/CT images, which are likely to affect the physician's diagnosis. In this paper, the causes of artifacts are analyzed, and the methods for solving the artifacts are summarized.
