Abstract
Until recently, computed tomography coronary angiography was restricted to the anatomical assessment of coronary stenosis, whereas the functional significance of coronary lesions remained outside of its scope. Nevertheless, the kinetics of iodinated contrast is similar to gadolinium-diethylenetriamine pentaacetic acid used in contrast-enhanced magnetic resonance imaging, allowing assessment of myocardial perfusion and viability by cardiac computed tomography.
摘要
直到最近，计算机断层扫描冠状动脉造影仍局限于对冠状动脉狭窄的解剖学评估，而冠状动脉病变的功能意义仍不在其评估范围内。然而，碘化造影剂的动力学与用于对比增强磁共振成像的钆-二乙烯三胺五乙酸相似，这使得通过心脏计算机断层扫描能够评估心肌灌注和存活情况。
