Thoracic aortic pathology carries significant morbidity and mortality, which requires prompt and accurate clinical and radiological evaluation. Advances in imaging technologies have improved our knowledge of the mechanisms of growth and rupture and our understanding of endovascular repair. Computed tomography has become a crucial component in this process, replacing catheter-based angiography as the most commonly used pre- and postoperative imaging modality for the thoracic aorta. Functional imaging methods such as magnetic resonance and echocardiography are evolving and are able to provide the clinically relevant anatomic, haemodynamic and biomechanical information that is necessary for accurate diagnosis, risk stratification and selection of the appropriate treatment for an individual patient. The availability of advanced image acquisition expertise and equipment is spreading to a growing number of institutions worldwide and will greatly enhance existing imaging strategies for patients with thoracic aortic pathology.
胸主动脉病变具有较高的发病率和死亡率，这需要及时、准确的临床和影像学评估。成像技术的进步增进了我们对生长和破裂机制的认识，以及对血管内修复的理解。计算机断层扫描已成为这一过程中的关键组成部分，取代了基于导管的血管造影术，成为胸主动脉最常用的术前和术后成像方式。诸如磁共振成像和超声心动图等功能成像方法正在不断发展，能够提供准确诊断、风险分层以及为个体患者选择合适治疗方案所需的临床相关解剖、血流动力学和生物力学信息。先进图像采集专业知识和设备在全球越来越多的机构中得到普及，这将极大地提升现有的胸主动脉病变患者成像策略。
