title: [Multislice thoracic CT scanner].
abstract: The scanner, or computed tomography, is the reference imaging test for most thoracic diseases in both adults and children. It has gone through tremendously rapid technological progress over the last few years with the appearance of multirow (or multidetector or multislice) scanners. This technology currently provides volume acquisition of a child's thorax in 2-5 s. These technological advances are particularly useful for exploring airway diseases, largely because of the range of reconstruction possibilities (maximum and minimum intensity projection, volume rendering, virtual endoscopy), which offer advantageous perspectives in pediatrics. Multiplanar imaging and above all three-dimensional imaging provide a totally original analysis in space of the sometimes complex relations between vascular and airway structures, making it possible to understand certain extrinsic bronchial compression mechanisms more precisely. The present study briefly reviews the technical aspects of the thoracic scanner in children and illustrates its role today in volume CT in childhood thoracic diseases using clinical examples taken from our daily practice.
