Imaging, particularly computed tomography (CT) and magnetic resonance imaging (MRI), plays a central role in the diagnostics, treatment planning and follow-up of aortic diseases. While ultrasound is often used for the initial assessment, CT enables rapid and comprehensive imaging of the aorta. The MRI is a radiation-free and when necessary, contrast agent-free alternative and provides functional imaging methods. Positron emission tomography (PET) is particularly relevant for inflammatory vascular diseases. Cross-sectional imaging has recently undergone significant development, particularly with respect to image quality and the required doses of ionizing radiation and contrast agents, spatial resolution and newer methods, such as material decomposition and functional imaging. This article provides an overview of current developments in CT angiography (CTA) and magnetic resonance angiography (MRA) and their use in selected aortic diseases in the context of the latest guidelines.
成像，尤其是计算机断层扫描（CT）和磁共振成像（MRI），在主动脉疾病的诊断、治疗规划及随访中发挥着核心作用。虽然超声常被用于初步评估，但CT能对主动脉进行快速且全面的成像。MRI是一种无辐射且必要时无需使用造影剂的替代方法，并提供功能成像手段。正电子发射断层扫描（PET）对炎症性血管疾病尤为重要。横断面成像近来取得了显著进展，特别是在图像质量、所需电离辐射剂量和造影剂剂量、空间分辨率以及诸如物质分解和功能成像等新方法方面。本文概述了CT血管造影（CTA）和磁共振血管造影（MRA）的当前进展及其在最新指南背景下在特定主动脉疾病中的应用。
