Recent advancement of MDCT provides high-resolution axial images with optimal contrast enhancement and 3D reformatted images of the thoracic aorta. MDCT is now playing a dominant and critical role in the evaluation of thoracic aortic disease. This article will focus on procedural considerations of MDCT: acquisition parameters, contrast injection and post-processing techniques and imaging findings of thoracic aortic diseases including, aortic dissection, intramural hematoma, penetrating atherosclerotic ulcer, aneurysm, and traumatic injury.
多层螺旋CT（MDCT）的最新进展能够提供具有最佳对比增强效果的高分辨率轴向图像以及胸主动脉的三维重建图像。MDCT目前在胸主动脉疾病的评估中发挥着主导且关键的作用。本文将重点关注MDCT的操作要点：采集参数、对比剂注射及后处理技术，以及胸主动脉疾病的影像表现，包括主动脉夹层、壁内血肿、穿透性动脉粥样硬化性溃疡、动脉瘤和创伤性损伤。
