X-ray CT of the heart is an evolving field. The ultrafast CT scanner provides a practical method of applying the high spatial resolution, high density resolution, and tomographic capabilities of conventional CT scanning, permitting an evaluation of the cardiovascular system. Multiple reports demonstrate that the basic ultrafast technology, while in an evolving state, permits comprehensive evaluation of cardiac structure and function. Recent studies suggest that with further modification ultrafast CT may ultimately be able to delineate the anatomy of the proximal coronary arteries and bypass grafts and to quantitate perfusion. If all these are possible, x-ray CT will have an expanded role in the evaluation of patients with known or suspected heart disease.
心脏的X线计算机断层扫描（CT）是一个不断发展的领域。超快速CT扫描仪提供了一种切实可行的方法，可应用传统CT扫描的高空间分辨率、高密度分辨率和断层扫描能力，从而对心血管系统进行评估。多项报告表明，尽管基本的超快速技术仍处于发展状态，但它能够对心脏结构和功能进行全面评估。最近的研究表明，通过进一步改进，超快速CT最终或许能够描绘近端冠状动脉和旁路移植物的解剖结构，并对灌注进行定量分析。如果所有这些都能实现，那么X线CT在已知或疑似心脏病患者的评估中将发挥更大的作用。
