title: Chest CT in infants and children.
abstract: Computed tomography (CT) is a powerful and irreplaceable imaging technique in the evaluation of thoracic disease in infants and children. Recent advances in CT technology, with multi-detector equipment now widely available in most institutions, allowing a highly detailed evaluation of the chest in a short time period has resulted in expanding indications of chest CT in paediatric patients. Its improved diagnostic yield along with a widespread availability has also resulted in an increased number of CT examinations in children, not always with beneficial impact on patient management and outcome. Accordingly with the ALARA concept, a judicious and correct use of CT is strongly advisable in order to reduce unnecessary high dose radiation exposure. The objective of this paper is to review the use of chest CT in paediatric patients focused mainly on basic technical aspects and clinical applications in the evaluation of the lungs, mediastinum and chest wall.
