Multidetector computed tomography (MDCT) imaging, a technological advance over traditional CT, is a promising possible alternative to cardiac catheterization for evaluating patients with chest pain in the emergency department (ED). In comparison with traditional CT, MDCT offers increased spatial and temporal resolution that allows reliable visualization of the coronary arteries. In addition, a "triple scan," which includes evaluation for pulmonary embolism and thoracic aortic dissection, can be incorporated into a single study. This test will enable emergency physicians to rapidly evaluate patients for life-threatening illnesses and may allow safer and earlier discharges of many patients with chest pain in comparison with a traditional rule-out protocol. In this article, we will highlight the technological advances of MDCT imaging, review the literature on coronary angiography via MDCT, and discuss the future of this technology as it relates to the ED.
多排螺旋计算机断层扫描（MDCT）成像技术相较于传统CT有了进步，在急诊科（ED）评估胸痛患者时，它有望成为心脏导管插入术的一种替代方案。与传统CT相比，MDCT具有更高的空间和时间分辨率，能够可靠地显示冠状动脉。此外，一项包括肺栓塞和胸主动脉夹层评估的“三联扫描”可纳入单次检查中。这项检查能够使急诊医生快速评估患者是否患有危及生命的疾病，并且与传统的排除方案相比，可能让许多胸痛患者更安全、更早出院。在本文中，我们将重点介绍MDCT成像的技术进步，回顾通过MDCT进行冠状动脉造影的文献，并讨论这项技术在急诊科的未来发展。
