Abstract

This brief report aimed to show the utility of photon-counting technology alongside standard cranial imaging protocols for visualizing shunt valves in a patient's cranial computed tomography scan. Photon-counting CT scans with cranial protocols were retrospectively surveyed and four types of shunt valves were encountered: proGAV 2.0^®, M.blue^®, Codman Certas^®, and proSA^®. These scans were compared with those obtained from non-photon-counting scanners at different time points for the same patients. The analysis of these findings demonstrated the usefulness of photon-counting technology for the clear and precise visualization of shunt valves without any additional radiation or special reconstruction patterns. The enhanced utility of photon-counting is highlighted by providing superior spatial resolution compared to other CT detectors. This technology facilitates a more accurate characterization of shunt valves and may support the detection of subtle abnormalities and a precise assessment of shunt valves.

利用光子计数扫描仪对头颅 CT 扫描中的分流阀进行高级成像。

这份简短的报告旨在展示光子计数技术与标准头颅成像协议在患者头颅计算机断层扫描中显示分流瓣膜方面的实用性。我们对采用头颅协议的光子计数 CT 扫描进行了回顾性调查，发现了四种类型的分流瓣膜：proGAV 2.0®、M.blue®、Codman Certas® 和 proSA®。这些扫描结果与非光子计数扫描仪在同一患者的不同时间点获得的扫描结果进行了比较。对这些结果的分析表明，光子计数技术可以清晰、精确地显示分流瓣，而无需额外的辐射或特殊的重建模式。与其他 CT 探测器相比，光子计数技术具有更高的空间分辨率，从而凸显了其更强的实用性。该技术有助于更准确地描述分流瓣膜的特征，并有助于检测细微异常和精确评估分流瓣膜。

期刊介绍： TomographyTM publishes basic (technical and pre-clinical) and clinical scientific articles which involve the advancement of imaging technologies. Tomography encompasses studies that use single or multiple imaging modalities including for example CT, US, PET, SPECT, MR and hyperpolarization technologies, as well as optical modalities (i.e. bioluminescence, photoacoustic, endomicroscopy, fiber optic imaging and optical computed tomography) in basic sciences, engineering, preclinical and clinical medicine. Tomography also welcomes studies involving exploration and refinement of contrast mechanisms and image-derived metrics within and across modalities toward the development of novel imaging probes for image-based feedback and intervention. The use of imaging in biology and medicine provides unparalleled opportunities to noninvasively interrogate tissues to obtain real-time dynamic and quantitative information required for diagnosis and response to interventions and to follow evolving pathological conditions. As multi-modal studies and the complexities of imaging technologies themselves are ever increasing to provide advanced information to scientists and clinicians. Tomography provides a unique publication venue allowing investigators the opportunity to more precisely communicate integrated findings related to the diverse and heterogeneous features associated with underlying anatomical, physiological, functional, metabolic and molecular genetic activities of normal and diseased tissue. Thus Tomography publishes peer-reviewed articles which involve the broad use of imaging of any tissue and disease type including both preclinical and clinical investigations. In addition, hardware/software along with chemical and molecular probe advances are welcome as they are deemed to significantly contribute towards the long-term goal of improving the overall impact of imaging on scientific and clinical discovery.
