摘要
PET/CT实现了PET与CT同机图像融合,为肿瘤显像提供了一种新的诊断技术。本文简要介绍PET/CT有关的几个技术问题和临床应用方面的新进展,如晶体的选择、CT技术进展、放射治疗、衰减校正、呼吸运动及CT造影剂的影响等。
PET/CT offers the unique ability to acquire PET and CT data with rapid full body registration in a single scanning session,and starts new diagnostic strategies in oncology imaging.Some new advances of research and clinical study on PET/CT were summarized briefly,including the choice of crystals,development of CT,radiotherapy plan,attenuation correction with CT,respiratory motion and CT contrast induced artifacts.
