The most common imaging modality used for diagnosis of aortic disease is CT, followed by transesophageal echocardiography, MRI, and aortography. If multiple imaging is performed, the initial imaging technique most frequently employed is computerized tomography. During the past decade, computed tomographic angiography (CTA) has become a standard non-invasive imaging modality for the depiction of vascular anatomy and pathology. The quality and speed of CTA examinations have increased dramatically as CT technology has evolved from-channel spiral CT systems to multichannel (4-, 8-, 10- and 16-slice) spiral CT system. The quality and speed of CTA is superior to other imaging modalities, and it is also cheaper and less invasive. CTA of the aorta has proven to be superior in diagnostic accuracy to conventional arteriography in several applications.
用于诊断主动脉疾病最常用的成像方式是CT，其次是经食管超声心动图、MRI和主动脉造影。如果进行多种成像检查，最常采用的初始成像技术是计算机断层扫描。在过去十年中，计算机断层血管造影（CTA）已成为用于描绘血管解剖结构和病理状况的标准非侵入性成像方式。随着CT技术从单通道螺旋CT系统发展到多通道（4层、8层、10层和16层）螺旋CT系统，CTA检查的质量和速度有了显著提高。CTA的质量和速度优于其他成像方式，而且成本更低、侵入性更小。在一些应用中，主动脉CTA已被证明在诊断准确性上优于传统动脉造影。
