摘要: PET-CT实现了PET和CT的同机图像融合,但由于CT用于衰减校正以及PET和CT图像采集的非完全同时性,PET-CT图像存在一定伪影,临床中这些伪影的存在会干扰医师对图像的判读,带来假阳性或假阴性。本文主要介绍PET-CT的有关伪影,分析其产生原因,并探讨其可能的预防措施。

Abstract: PET-CT realized the image fusion of PET and CT in one single machine. But some technical reasons such as X-ray-based attenuation correction and nonsimuhaneous acquisition between PET and CT lead to some PET-CT artifacts which interrupt the image interpretation and may cause false-positive or falsenegative diagnosis. This review will talk about these artifacts, analyze the causes and discuss the possible preventive measures.
