BACKGROUND
The introduction of photon-counting detector computed tomography (PCD-CT) heralds a new generation of cardiac imaging.
OBJECTIVES
This review discusses the current scientific literature to determine the incremental value of PCD-CT in cardiac imaging.
METHODS
Discussion of currently available literature regarding cardiac PCD-CT from a radiological perspective.
RESULTS
Since its market introduction in 2021, numerous studies have explored the advantages of this new technology in the field of cardiac imaging, including improved image quality through superior spatial resolution, a higher contrast-to-noise ratio, reduced artifacts, and lower radiation dose.
CONCLUSION
While preliminary studies have been promising, it remains to be seen how the advantages of PCD-CT will affect clinical guidelines for cardiac CT.
背景
光子计数探测器计算机断层扫描（PCD-CT）的引入预示着新一代心脏成像技术的诞生。
目的
本综述探讨当前科学文献，以确定PCD-CT在心脏成像中的增量价值。
方法
从放射学角度讨论目前有关心脏PCD-CT的可用文献。
结果
自2021年进入市场以来，众多研究探索了这项新技术在心脏成像领域的优势，包括通过卓越的空间分辨率提高图像质量、更高的对比噪声比、减少伪影以及降低辐射剂量。
结论
虽然初步研究前景乐观，但PCD-CT的优势将如何影响心脏CT的临床指南仍有待观察。
