Four-dimensional flow MRI (4D flow MRI) plays a significant role in cardiovascular imaging, which provides new insights into the pathophysiology of disease. In this study, 4D flow with echo-planar imaging was introduced to evaluate the hemodynamic parameters of patients with abdominal aortic aneurysm, including velocity, flow and wall shear stress. We propose that 4D EPI flow can find differences of the above parameters between abdominal aortic aneurysm and normal abdominal aorta and has potential to be used for hemodynamics assessment in AAA patients.
