Noninvasive cardiac imaging is widely used to evaluate the presence of coronary artery disease. Recently, with improvements in imaging technology, noninvasive imaging has also been used for evaluation of the presence, severity, and prognosis of coronary artery disease. Coronary CT angiography and MRI of coronary arteries provide an anatomical assessment of coronary stenosis, whereas the hemodynamic significance of a coronary artery stenosis can be assessed by stress myocardial perfusion imaging, such as SPECT/PET and stress MRI. For appropriate use of multiple imaging modalities, the strengths and limitations of each modality are discussed in this review.
无创心脏成像被广泛用于评估冠状动脉疾病的存在情况。近年来,随着成像技术的改进,无创成像也已用于评估冠状动脉疾病的存在、严重程度和预后。冠状动脉CT血管造影和冠状动脉MRI可提供冠状动脉狭窄的解剖学评估,而冠状动脉狭窄的血流动力学意义可通过负荷心肌灌注成像来评估,如单光子发射计算机断层扫描/正电子发射断层扫描(SPECT/PET)和负荷MRI。为了合理使用多种成像模式,本综述将讨论每种模式的优缺点。
