Chronic aortic dissection comprises a heterogeneous group of unrepaired and repaired disease requiring lifelong clinical and imaging surveillance. CT and MRI are the main imaging modalities for longitudinal surveillance, with growing interest in emerging imaging techniques for prognostic potential. Imaging difficulties span technical and diagnostic challenges, some of which are unique to the repaired aorta, with specific complications depending on the type of repair. This review describes existing and emerging imaging techniques, outlines the technical and diagnostic challenges encountered at CT and MRI, and highlights the diagnostic pitfalls of chronic aortic dissection.
慢性主动脉夹层是一组异质性的未修复和修复疾病，需要终身进行临床和影像学监测。CT 和 MRI 是纵向监测的主要影像学手段，新兴的影像学技术在预测预后方面的应用日益受到关注。影像学方面的困难包括技术和诊断方面的挑战，其中一些是修复后的主动脉所特有的，具体并发症取决于修复的类型。本文描述了现有的和新兴的影像学技术，概述了 CT 和 MRI 检查中遇到的技术和诊断挑战，并强调了慢性主动脉夹层的诊断陷阱。
