Zusammenfassung
Die Mehrschicht-CT (Multislice-CT, MSCT) wurde in den letzten Jahren zur wichtigsten diagnostischen Stütze bei der Thoraxdiagnostik im Kindes- und Jugendalter. Das höhere stochastische Strahlenrisiko in dieser Altersgruppe im Vergleich zu Erwachsenen bedingt eine besonders umsichtige Handhabung der MSCT. In dieser Übersichtsarbeit werden unterschiedliche Möglichkeiten zur Reduktion der Strahlenexposition bei Kindern verschiedener Altersgruppen abgehandelt.
Abstract
In the past years, multislice CT (MS-CT) has become an important diagnostic modality for the radiological evaluation of the thorax in children and adolescents. However, the higher stochastic radiation risks in pediatric patients, as compared to adults, necessitate a prudent use of MS-CT. This article presents an overview of the benefits of multislice CT and a variety of possibilities for radiation reduction in pediatric patients of different ages.
