Purpose or Case Report: Photon-counting CT scanners, a recent generational leap in CT technology, offer immense potential in reducing electron noise and elevating image quality. Photon-counting computed tomography (PCCT) stands apart from traditional CT scans through its revolutionary scanning process. Unlike conventional CT scans, which rely on a two-step process to convert X-rays into visible light, photon-counting CT scanners directly transform X-ray photons into electrical signals, effectively minimizing electronic noise. The intrinsic features of PCCT, relying on semiconductor technologies, bring about a significant reduction in electron noise and an enhancement in spatial resolution. This, in turn, yields high-quality images while concurrently lowering radiation doses compared to traditional CT scans. The application of photon-counting detectors in pediatric imaging has been the subject of extensive study, with promising results showcased in initial clinical experiences, especially in pediatric chest imaging. This development is particularly critical given the heightened radiation sensitivity of children when compared to adults. In the United States alone, where over 5 million pediatric CT scans are performed each year, the need to lower radiation exposure is a serious concern. In conclusion, photon-counting CT scanners represent a promising technological advancement with the capacity to improve image quality and reduce radiation exposure in pediatric patients. The ongoing research and development in this field hold the promise of even more substantial enhancements in CT technology, contributing to safer radiation exposure and improved imaging outcomes. This exhibit will review the current PCCT literature and provide case examples of how this technology can implemented in a pediatric setting.
