The new imaging methods, cine computerized tomography (cine-CT) and magnetic resonance imaging (MRI), are reviewed as tools for cardiac output (CO) measurement. Both modalities provide accurate and highly reproducible measurements of stroke volume and CO at rest. The methods are less applicable during heavy physical exercise. Because of cost and lack of equipment the methods are not practical for measurements of CO alone in the foreseeable future. However, cine-CT and MRI may be of value for CO measurements when additional characteristics, such as wall motion, myocardial structure and tissue perfusion, need to be assessed.
本文综述了电影计算机断层扫描（cine-CT）和磁共振成像（MRI）这两种新型成像方法作为心输出量（CO）测量工具的情况。这两种方法在静息状态下均可准确且高度可重复地测量每搏输出量和心输出量。在剧烈体育锻炼时，这些方法的适用性较差。由于成本和设备短缺问题，在可预见的未来，仅用于测量心输出量时，这些方法并不实用。然而，当需要评估诸如室壁运动、心肌结构和组织灌注等其他特征时，cine-CT和MRI在心输出量测量中可能具有价值。
