Endovascular repair of aortic aneurysm mainly depends on preoperative monitoring, intraoperative management and postoperative follow-up based on radiological imaging technology. Ultrasound, computed tomography (CT), magnetic resonance imaging (MRI), and angiography all play their roles in different stages of treatment. Usually, one imaging modality supports another one by providing additional information. A variety of imaging data must be integrated into a coherent program to manage patients with aortic aneurysms during treatment and follow-up.
