MDCT systems with fast scanning capabilities can acquire images of the thorax with reduced cardiac motion artifacts, enabling improved evaluation of the heart and surrounding structures in the course of routine thoracic CT. This article describes the principles of including an evaluation of the heart in the course of a chest CT examination in terms of both examination technique and image interpretation. In addition, both the normal appearances and some of the most common abnormal appearances of the cardiac structures will be described.
Details concerning the cardiac structures can inform interpretation of thoracic CT studies and can influence the patient's clinical management. Both unenhanced and contrast-enhanced scans can detect significant cardiac disorders that may otherwise go undetected. In certain situations, a CT examination of the entire chest, complemented by cardiac gating, can provide a more dedicated analysis of the heart and coronary arteries, providing both morphologic and functional information.
具有快速扫描能力的MDCT系统能够获取胸部图像，减少心脏运动伪影，从而在常规胸部CT检查过程中更好地评估心脏及周围结构。本文从检查技术和图像解读两方面描述了在胸部CT检查过程中对心脏进行评估的原则。此外，还将描述心脏结构的正常表现和一些最常见的异常表现。
有关心脏结构的细节能够为胸部CT研究的解读提供信息，并可能影响患者的临床管理。平扫和增强扫描都能检测出原本可能未被发现的重大心脏疾病。在某些情况下，对整个胸部进行CT检查并辅以心脏门控，可以对心脏和冠状动脉进行更专门的分析，提供形态学和功能信息。
