Abstract

There has been a revolution in the technology of helical computed tomography, with increased speed of acquisition of the CT examinations, improvements in image quality, reduction in volume of intravenous contrast material required and a significant reduction in the need for sedation. All of these technological improvements have particular clinical benefits for children. Indeed many of the significant advances in CT technology are invaluable when studying the airways and cardiovascular structures. These improvements in CT angiography, with consequent isotropic resolution, allow excellent quality multiplanar reconstructions, with holographic three-dimensional reformatted images, available to clinicians that will facilitate best clinical diagnostic and surgical planning. The positive benefits of CT must be considered in the light of potential radiation exposure risks. We are obliged to produce low-dose, weight-based paediatric protocols, which are optimised to provide images that are ‘fit for diagnostic purpose’. We use this chapter as an opportunity to outline the technical aspects of helical MDCT technique, the many potential clinical indications where thoracic CT may benefit children, and we suggest protocols which may be used in children—a very precious commodity!
