Photon-counting computed tomography (PCCT) imaging uses a new detector technology to provide added information beyond what can already be obtained with current CT and MR technologies. This review provides an overview of PCCT of the abdomen and focuses specifically on applications that benefit the most from this new imaging technique. We describe the requirements for a successful abdominal PCCT acquisition and the challenges for clinical translation. The review highlights work done within the last year with an emphasis on new protocols that have been tested in clinical practice. Applications of PCCT include imaging of cystic lesions, sources of bleeding, and cancers. Photon-counting CT is positioned to move beyond detection of disease to better quantitative staging of disease and measurement of treatment response.
光子计数计算机断层扫描（PCCT）成像使用一种新的探测器技术，提供了超越当前 CT 和 MR 技术所能获得的额外信息。本综述概述了腹部 PCCT，并特别关注了最受益于这种新成像技术的应用。我们描述了成功进行腹部 PCCT 采集的要求和临床转化的挑战。该综述强调了过去一年中所做的工作，重点介绍了已在临床实践中测试的新方案。PCCT 的应用包括囊性病变、出血源和癌症的成像。光子计数 CT 有望超越疾病的检测，更好地进行疾病的定量分期和治疗反应的测量。
