摘要
双显像剂PET显像能够为疾病诊断提供更为全面的临床信息.如何通过单次显像实现双显像剂显像是当前核医学领域研究热点,其核心技术问题是在混合显像剂信号中准确分离出单一显像剂信息.近20年来,不同显像剂的分离方法不断被提出,2种显像剂之间的注射间隔也在不断缩短.该文对近年来提出的双显像剂分离技术进行汇总,介绍了代表性技术的实现手段,总结了各种方法的优势,并展望其发展方向.
Abstract
Dual-tracer PET imaging can provide more comprehensive clinical information for dis-ease diagnosis.How to achieve dual-tracer imaging through single imaging session is one of the hot topics in the field of nuclear medicine.The key issues in achieving dual-tracer imaging with a single scan is the accu-rate separation of single-tracer information from the mixed tracer signal.In the last two decades,separation methods for different tracers have been proposed,and the injection interval between two tracers was reduced.This paper summarizes recent dual-tracer separation methods.The basic principles,features and advantages of separation methods are analyzed.Besides,the outlook on the future development of dual-tracer separation is also discussed in the present review.
