Rapid, noninvasive imaging approaches can provide novel diagnostic information and, when effectively interpreted and implemented in a therapeutic strategy, can simplify procedures. Endovascular therapy of thoracic and abdominal aortic disease represents a dramatic shift in treatment of thoracoabdominal aortic disease, but one that requires a change in the knowledge base regarding both the morphology and pathophysiology of aortic disease and the interaction with interventional devices. As a result, the demands on cross-sectional imaging have increased commensurately with the complexity of the therapeutic options, but advances in cross-sectional imaging have kept pace. Current computed tomography (CT) and magnetic resonance imaging (MRI) technologies provide detailed morphologic assessment, and are advancing rapidly into more sophisticated physiologic evaluation of aortic disease. These advances may more effectively triage patients to appropriate therapy, or exclude patients from unnecessary invasive procedures. The information gleaned from CT and MRI studies is critical for the vascular surgeon who wants to identify appropriate vascular territories for intervention, plan a detailed approach, and develop sophisticated surveillance strategies.
快速、无创的成像方法能够提供全新的诊断信息，并且在治疗策略中得到有效解读和应用时，能够简化程序。胸主动脉和腹主动脉疾病的血管内治疗代表了胸腹主动脉疾病治疗的巨大转变，但这需要改变关于主动脉疾病形态学和病理生理学以及与介入装置相互作用的知识库。因此，随着治疗选择的复杂性增加，对横断面成像的需求也相应增加，但横断面成像技术也在同步发展。当前的计算机断层扫描（CT）和磁共振成像（MRI）技术可提供详细的形态学评估，并正迅速发展为对主动脉疾病进行更复杂的生理学评估。这些进展可能会更有效地将患者分类至合适的治疗方案，或使患者免于不必要的侵入性手术。对于想要确定合适的干预血管区域、规划详细方法并制定精密监测策略的血管外科医生而言，从CT和MRI研究中收集到的信息至关重要。
