Abstract：
Photon-counting detector CT (PCD CT) is a promising technology for abdominal imaging due to its ability to provide high spatial and contrast resolution images with reduced patient radiation exposure. However, there is currently no consensus regarding the optimal imaging protocols for PCD CT. This article aims to present the PCD CT abdominal imaging protocols used by two tertiary care academic centers in the United States.
A review of PCD CT abdominal imaging protocols was conducted by two abdominal radiologists at different academic institutions. Protocols were compared in terms of acquisition parameters and reconstruction settings. Both imaging centers independently selected similar protocols for PCD CT abdominal imaging, using QuantumPlus mode.
There were some differences in the use of reconstruction kernels and iterative reconstruction levels, however the individual combination at each site resulted in similar image impressions. Overall, the imaging protocols used by both centers provide high-quality images with low radiation exposure.
These findings provide valuable insights into the development of standardized protocols for PCD CT abdominal imaging, which can help to ensure consistent as well as high-quality imaging across different institutions and allow for future multicenter research collaborations.

摘要：
目的：光子计数探测器CT（PCDCT）是一种有前途的腹部成像技术，因为它能够在减少患者辐射暴露的情况下提供高空间和对比度分辨率的图像。然而,目前对于PCDCT的最佳成像方案尚无共识.本文旨在介绍美国两个三级护理学术中心使用的PCDCT腹部成像方案。
方法：由不同学术机构的两名腹部放射科医师对PCDCT腹部成像方案进行了综述。在采集参数和重建设置方面比较了协议。两个成像中心都独立选择了类似的PCDCT腹部成像方案，使用QuantumPlus模式。
结果：在使用重建内核和迭代重建级别方面存在一些差异，然而,每个站点的单独组合产生了相似的图像印象.总的来说,两个中心使用的成像方案可提供低辐射暴露的高质量图像.
结论：这些发现为PCDCT腹部成像标准化方案的发展提供了有价值的见解，这可以帮助确保不同机构之间的一致和高质量成像，并允许未来的多中心研究合作。
