Zusammenfassung
Erkrankungen der Aorta sind mit einer hohen Morbidität und Mortalität assoziiert und erfordern insbesondere im Akutfall eine effiziente und akkurate Diagnostik. Die Mehrschicht-Spiral-CT (MSCT) mit der Möglichkeit der hochauflösenden CT-Angiographie (CTA) ist zur Methode der Wahl bei der Diagnosestellung und Verlaufskontrolle erworbener Aortenerkrankungen geworden. Unter den Notfällen ist die Aortendissektion am häufigsten, bleibt aber in bis zu 38% der Fälle unentdeckt. Mit der MSCT gelingt der Nachweis mit einer Sensitivität und Spezifität von über 99%. Für die Detektion inflammatorischer Veränderungen zeigt die CT eine Sensitivität von 83%, eine Spezifität von ca. 100% und eine diagnostische Genauigkeit von ca. 94%. Dieser Artikel vermittelt den aktuellen Stand der Wissenschaft in der CT-Bildgebung erworbener Aortenerkrankungen.
Abstract
Aortic disease is associated with high morbidity and mortality and thus require an efficient and accurate diagnostic approach, especially in the acute setting. Multislice computed tomography (MSCT) with the option of high-resolution CT angiography (CTA) has emerged as the standard of reference in diagnosis and follow-up of patients with acquired aortic disease. Aortic dissection is the most common aortic emergency, but it remains undiscovered in up to 38% of cases. Sensitivity and specificity of MSCT in the assessment of aortic dissection are greater than 99%. The sensitivity of CT in the detection of inflammatory changes is 83%; its specificity is almost 100%; and its diagnostic accuracy is ca. 94%. This article outlines state-of-the-art principles in diagnostic CT imaging of acquired aortic disease.
