Zusammenfassung
Die ersten computertomographischen Beschreibungen der Lungenmorphologie bei Patienten mit akutem Lungenversagen erschienen vor inzwischen 25 Jahren. Die Computertomographie (CT) hat das Verständnis pathophysiologischer Prozesse und therapeutischer Interventionen beim akuten Lungenversagen maßgeblich beeinflusst und sich von der Reservebildgebungsoption zum zentralen diagnostischen Baustein moderner Therapiekonzepte entwickelt. Der vorliegende Artikel soll einen Überblick über Indikationsstellung, Durchführung und Auswertung der CT bei Patienten mit akutem Lungenversagen geben. In der CT erfasste Veränderungen der Morphologie werden pathophysiologischen Eigenschaften der Lungenfunktion zugeordnet. Abschließend wird dargestellt, wie die CT zur Quantifizierung erkrankungs- oder beatmungsassoziierter Veränderungen der Lungenbelüftung eingesetzt werden kann.
Abstract
Since its first application in patients with acute lung injury 25 years ago, computed tomography (CT) has significantly influenced the understanding of the pathophysiology, diagnosis and management of acute lung injury and has become an important diagnostic modality for these patients. The aim of this article is to review important disease-specific aspects of CT acquisition and qualitative and quantitative analyses of CT data. Morphological changes seen on CT and associated functional alterations are discussed. Methods used for the quantification of lung aeration are described and their limitations outlined.
