冠脉CT与SPECT心肌灌注显像CTC
冠心病各种诊断手段层出不穷,心肌灌注显像(MPI)作为无创性心肌血流的功能评价手段,在临床应用几十年,积累了大量研究证据,用于冠心病的诊断、危险度分层(辅助治疗方法的决策)、评价疗效和预后评价。CT冠状动脉成像(CTCA)是近些年发展起来的新技术,随着高端甚至超高端CT的应用,CTCA在冠心病中的应用日益增加。如何正确、深刻认识这两种既有区别,又有联系的冠状动脉无创性诊断和评价手段,无论对影像医师和临床医师都显得十分重要。本讲座通过临床病例实战解析形式,对比分析二者在冠心病诊断、评价中的各自优势、不足及互补价值,力图阐明二者在当代冠心病诊治中的各自特色和应用价值。
