Noninvasive vascular imaging with computed tomography (CT) has become the clinical mainstay for many indications and body regions. The recent introduction of photon-counting detector (PCD)-CT into clinical routine has further broadened the spectrum of vascular applications. Technical improvements of PCD-CT, such as the decreased noise levels, improved contrast-to-noise ratio, and full spectral multienergy data information from every acquisition, have the potential to further impact on clinical decision making and ultimately on outcome of vascular patients. Early experience with the new PCD-CT technology demonstrates these improvements in various aspects. This review summarizes the main advantages of PCD-CT for vascular imaging a discussion of the PureLumen and PureCalcium algorithms.
计算机断层扫描（CT）的无创血管成像已成为许多适应症和身体部位的临床主流。最近将光子计数探测器（PCD）-CT 引入临床常规，进一步拓宽了血管应用的范围。PCD-CT 的技术改进，如降低噪声水平、提高对比噪声比以及从每次采集获得全谱多能量数据信息，有可能进一步影响临床决策，并最终影响血管患者的结果。对新的 PCD-CT 技术的早期经验表明，在各个方面都有这些改进。本文综述了 PCD-CT 在血管成像方面的主要优点，并讨论了 PureLumen 和 PureCalcium 算法。
