Zusammenfassung
Klinisches/methodisches Problem
Die Wahl des optimalen Untersuchungsprotokolls für eine CT der Lunge ist relevant für die diagnostische Aussagekraft.
Radiologische Standardverfahren
Die hochauflösende Computertomographie (HRCT) der Lunge ist das beste Verfahren zur nichtinvasiven Beurteilung des Lungenparenchyms.
Leistungsfähigkeit
Durch die Möglichkeit der Untersuchung der gesamten Lunge in einer Atemstillstandsphase ist die Abschätzung der Erkrankungsschwere problemlos möglich. Verschiedene Aspekte sind zu beachten, um eine optimale Bildqualität zu erreichen und eine bestmögliche Aussagekraft der Untersuchung zu gewährleisten.
Empfehlung für die Praxis
In dieser Übersicht werden die verschiedenen Aufnahmeparameter erläutert sowie das Thema der Dosisreduktion diskutiert.
Abstract
Clinical/methodical issue
For optimal visualization of the lung parenchyma a dedicated computed tomography (CT) examination protocol has to be selected.
Standard radiological methods
High resolution CT (HRCT) is the best technique for non-invasive evaluation of the lung parenchyma.
Achievements
Given the possibility to examine the complete lungs within one breath hold, assessment of disease severity and distribution is easily possible. Various parameters have to be considered to generate optimal image quality and best possible clinical results.
Practical recommendations
This review article discusses the various image acquisition parameters for HRCT as well as the issue of dose reduction.
