Abstract

Helical/spiral CT technology has several potential benefits for scanning pediatric patients. These benefits include reduced sedation rates, decreased radiation exposure with scanning at extended pitch, improved image quality, and better three-dimensional and reformatted images. This paper reviews the technical and clinical considerations relevant to scanning the pediatric patient and offers suggestions for protocol development.
