多探测器计算机断层扫描(CT)技术的最新进展极大地提高了CT显示心脏和冠状动脉的能力。注射造影剂后，可以获得相对可靠的冠状动脉成像，尽管由于空间和时间分辨率仍然有一定的限制，但会造成一些限制。几项研究表明，如果图像质量足够，可以高灵敏度和特异度检测到冠状动脉狭窄。更具挑战性的情况包括对接受支架和搭桥手术的患者进行成像。有几种临床应用被定义为“适当的”，包括对有症状但不能运动或负荷测试结果无法解释的患者使用CT血管造影术，或对急性胸痛患者使用CT血管造影术，这些患者有中度冠状动脉疾病的可能性，但缺乏心电图变化或心肌酶升高。可以预期，CT技术的进一步提高将有助于更牢固地确立CT冠状动脉造影的临床地位，并探索该技术的进一步应用。
The recent evolution of multidetector computed tomography (CT) technology has substantially improved the ability of CT to visualize the heart and coronary arteries. After injection of contrast agent, relatively reliable imaging of the coronary arteries can be achieved, even though some restrictions are caused because the spatial and temporal resolutions are still somewhat limited. Several studies have shown that stenoses of the native coronary arteries can be detected with high sensitivity and specificity if image quality is adequate. More challenging situations include imaging of patients with stents and bypass grafts. Several clinical applications have been defined as "appropriate" and include the use of CT angiography in patients who have symptoms but who cannot exercise or who have an uninterpretable stress test result, or in patients with acute chest pain of intermediate likelihood for coronary artery disease but lack of electrocardiographic changes or myocardial enzyme elevations. It can be expected that further improvement of CT technology will help to more firmly establish the clinical role of CT coronary angiography and to explore further applications of this technique.
