The aim of this work was to evaluate the usefulness of angiography, CT scan and MR imaging in the diagnosis of aortic dissection, on the basis of the authors' experience and literature review. Angiographic study is still considered the first choice technique in the diagnosis of aortic dissection, although it is considered not completely safe. CT scan allows to note the early thickening of the vessel walls (due to intraparietal bleeding) and the presence of calcifications in the thrombosed portion of the lesion. MR study allows multiplanar study of the lesions without contrast medium, and best visualization of subendothelial bleeding in dissections without intimal lesion.
基于作者的经验和文献综述，本研究旨在评估血管造影、CT扫描和磁共振成像在主动脉夹层诊断中的实用性。血管造影研究仍被认为是主动脉夹层诊断的首选技术，尽管它并非完全安全。CT扫描可以观察到血管壁早期增厚（由于壁内出血）以及病变血栓形成部分的钙化情况。磁共振研究可以在不使用造影剂的情况下对病变进行多平面研究，并且能更好地显示无内膜病变的夹层中内皮下出血情况。
