This systematic review and meta-analysis demonstrates that magnetic resonance imaging (MRI) is a more sensitive imaging modality than computed tomography angiography (CTA) for the detection of endoleaks in patients after endovascular abdominal aortic aneurysm repair (EVAR). Blood pooling contrast agents may have additional diagnostic value compared to extracellular gadolinium chelates.
