Noninvasive assessment of coronary artery disease remains a challenging task, with a large armamentarium of diagnostic modalities. Myocardial perfusion imaging (MPI) is widely used for this purpose whereby cardiac positron emission tomography (PET) is considered the gold standard. Next to relative radiotracer distribution, PET allows for measurement of absolute myocardial blood flow. This quantification of perfusion improves diagnostic accuracy and prognostic value. Cardiac hybrid imaging relies on the fusion of anatomical and functional imaging using coronary computed tomography angiography and MPI, respectively, and provides incremental value as compared with either stand-alone modality.
对冠状动脉疾病进行无创评估仍然是一项具有挑战性的任务,有大量的诊断方法。心肌灌注成像(MPI)广泛用于此目的,其中心脏正电子发射断层扫描(PET)被认为是金标准。除了相对放射性示踪剂分布外,PET还允许测量绝对心肌血流量。这种灌注定量提高了诊断准确性和预后价值。心脏混合成像分别依赖于使用冠状动脉计算机断层扫描血管造影和MPI的解剖学和功能成像的融合,与任何一种单独的模式相比都提供了额外的价值。
