Why the study?
Pediatric CT presents unique challenges including motion, smaller anatomy, and radiation risks, making guidance on protocol development for photon-counting detector CT valuable to realize its technical benefits.
This document provides multi-institutional protocol guidance to help optimize photon-counting detector CT imaging for pediatric patients.
PCD CT may improve pediatric imaging safety via lower dose and higher resolution; leaves open prospective outcome trials before routine adoption.
Performing CT in children comes with unique challenges such as greater degrees of patient motion, smaller and densely packed anatomy, and potential risks of radiation exposure. The technical advancements of photon-counting detector (PCD) CT enable decreased radiation dose and noise, as well as increased spatial and contrast resolution across all ages, compared with conventional energy-integrating detector CT. It is therefore valuable to review the relevant technical aspects and principles specific to protocol development on the new PCD CT platform to realize the potential benefits for this population. The purpose of this article, based on multi-institutional clinical and research experience from pediatric radiologists and medical physicists, is to provide protocol guidance for use of PCD CT in the imaging of pediatric patients.
