摘要目的腹主动脉瘤(AAA)根据其直径进行管理。常用CT血管成像(CTA),但其具有辐射并需要碘对比剂。非增强MRI是一种有前景的替代方法,可以更好地显示腔内血栓(ILT)的特征。本研究旨在证实:(1)非增强MRI测量AAA直径;(2)用CTA和MRI评估ILT。方法 28例腹主动脉瘤病人[直径(50.7±12.3)mm]行CTA和非增强MRI。MRI检查设

Abstract Objective Abdominal aortic aneurysm (AAA) is managed according to its diameter. CT angiography (CTA) is commonly used, but it has radiation and requires iodine contrast agent. Non-enhanced MRI is a promising alternative to better demonstrate the characteristics of luminal thrombus (ILT). This study was designed to confirm: (1) non-enhanced MRI measurement of AAA diameter; (2) CTA and MRI to assess ILT. Methods 28 patients with abdominal aortic aneurysm [diameter (50.7 ± 12.3) mm] underwent CTA and non-enhanced MRI. MRI examination set
