Zusammenfassung

Aortenerkrankungen können je nach Krankheitsbild und Akuität mit unterschiedlichen bildgebenden Verfahren untersucht werden. Modalitäten und Qualität der Bildgebung haben sich in den vergangenen Jahren rasant weiterentwickelt. Gemeinsam mit der klinischen Einschätzung eines betroffenen Patienten ist sie wegweisend für das weitere Management. Neben der eigentlichen Diagnosestellung sind die erhobenen Befunde auch Basis für die weitere Indikationsstellung, Therapieplanung, Therapiekontrolle und Verlaufsbeurteilung. Während die Katheterangiographie und der intravaskuläre Ultraschall nur noch in Ausnahmefällen und dann in Kombination mit einer interventionellen Therapie zur Anwendung kommen, stehen heute Schnittbildverfahren wie die kontrastverstärkte computertomographische Angiographie und die Magnetresonanztomographie im Zentrum der diagnostischen Abklärung. Den sich stetig verbessernden sonographischen Verfahren kommt vor allem im Rahmen von Screeninguntersuchungen, aber auch in der prä- und posttherapeutischen Verlaufsbeobachtung eine immer wichtigere Rolle zu. Therapeutisch relevante Zusatzinformationen können mithilfe der molekularen Bildgebung in der Positronenemissionstomographie/Computertomographie gewonnen werden.

Abstract

Depending on the type and acuteness, diseases of the aorta can be imaged by a variety of techniques. Modalities and quality of imaging have developed rapidly in recent years. In combination with the clinical assessment of patients, the results obtained by imaging determine the further management. They not only establish the underlying diagnosis but provide the information essential for indications, planning and reassessment of therapy, as well as for evaluation of the clinical course and surveillance. Whereas conventional catheter-guided angiography and intravascular ultrasound are only used in exceptional cases and then in conjunction with interventional therapy, cross-sectional imaging modalities, such as contrast-enhanced computed tomography (CT) angiography and magnetic resonance imaging (MRI) are nowadays the mainstay of diagnostics. Ultrasound techniques are improving steadily and are gaining increasing importance, e. g. for screening purposes and for pretherapeutic and posttherapeutic surveillance. Additional information of therapeutic relevance may be acquired by means of molecular imaging with positron emission tomography (PET) CT.
