In the past, thoracic and cardiac imaging were two distinct specialties of radiology. The technical evolution, however, has changed their boundaries with an important impact on CT imaging practices and has opened the new era of "cardiothoracic" imaging, due to the strong anatomic, mechanical, physiologic, physiopathologic, and therapeutic cardiopulmonary correlations. Modern thoracic radiologists can no longer avoid the assessment of heart and coronary arteries, as they used to do with earlier generations of CT scanner. The advent of ECG gating and state-of-art CT scanner faster rotation speed, high spatial and temporal resolution, high-pitch mode, shorter acquisition time, and dedicated cardiac reconstruction algorithms has opened new possibilities for chest imaging, integrating cardiac morphologic and even functional information within a diagnostic chest CT scan. The aim of this review is to briefly show and summarize the concept of integrated cardiothoracic imaging, which redefines the boundaries of chest CT imaging, opening the door to a new radiologic specialty.
过去，胸部和心脏成像曾是放射学中两个截然不同的专业领域。然而，技术的发展改变了它们的界限，对CT成像实践产生了重大影响，并开启了“心胸”成像的新时代，这是由于心肺在解剖学、力学、生理学、病理生理学及治疗方面存在紧密的相关性。现代胸部放射科医生再也不能像早期CT扫描仪时代那样，回避对心脏和冠状动脉的评估。心电图门控技术的出现以及最先进的CT扫描仪更快的旋转速度、高空间和时间分辨率、高螺距模式、更短的采集时间以及专门的心脏重建算法，为胸部成像开辟了新的可能性，能在诊断性胸部CT扫描中整合心脏形态学甚至功能信息。这篇综述的目的是简要展示并总结整合心胸成像的概念，该概念重新定义了胸部CT成像的界限，为一个新的放射学专业领域打开了大门。
