Abstract:
For the past decade, the diagnosis and treatment of coronary artery disease (CAD) has shifted from the traditional model by evaluating coronary artery stenosis with morphological imaging methods to a novel model by focusing on the detection of ischemia for risk stratification. The myocardial perfusion imaging (MPI) using stress single photon emission computed tomography (SPECT) has become the most commonly used stress imaging technique for the diagnosis and treatment of patients with suspected or known CAD. It has got strong supports, including those of the American College of Cardiology, American Heart Association, American Society of Nuclear Cardiology (ACC/AHA/ASNC) and other numerous clinical guidelines. They all stressed that the SPECT MPI is recommended to be used as the "gate keeper" to coronary angiography in order to prevent unnecessary intervention test and save the cost. However, in China the introduction and application of nuclear cardiology was late and highly unbalanced. This leads to the lack of understanding of nuclear cardiology in some clinicians, and there often is misunderstanding on correct selection of coronary angiography, cardiac CT, CT coronary angiography and others for diagnosis and treatment of CAD which results in a trend of over-application of these traditional techniques. In this article, we will focus on the status of nuclear cardiology, including SPECT, positron emission tomography (PET) MPI in the patients with CAD for the diagnosis of ischemia, risk stratification and management decision-making, and also compare it with the traditional morphological imaging techniques. In addition, we will briefly introduce the recent advances in cardiac hybrid imaging and molecular imaging. The aim of this paper is to popularize the knowledge of nuclear cardiology, and promote the rational application of nuclear cardiology in China.
