Endovascular repair for abdominal aortic aneurysm (EVAR) requires life-long postoperative imaging follow-up to detect complications. Prior work has shown that MRI with a blood pool agent with 85% albumin binding is more sensitive than CTA for endoleak detection, especially for slow flow and type II endoleaks. This work found that a gadolinium contrast agent with just 5% albumin binding is highly sensitive for the detection of endoleaks in patients with AAA growth and no or uncertain endoleak on CT angiography.
