摘要

The advent of photon counting detector computed tomography (PCD-CT) holds the promise of radiation reduction, improved spatial resolution, and spectral data for material decomposition in pediatric abdominal radiology, but effort is required to achieve this. Consensus lacks on what a good pediatric abdominal protocol should entail, and new features and hardware require a learning curve. This investigative review addresses and investigates the key software and hardware parameters of PCD-CT by testing progressively complex phantoms. Based on these tests, a pediatric abdominal PCD-CT protocol was derived for children up to 12 years, and preliminary clinical results are presented. Pediatric radiologists adopting PCD-CT can benefit from our early experience and use this review to adapt the proposed protocol to their needs.
