Hemodynamic parameters of patients with and without thoracic aortic atherosclerotic plaques were detected using a compressed sensing (CS) 4d flow sequence. Eight different planes perpendicular to the thoracic aorta were identified to confirm if there were differences in hemodynamic parameters between the plaque and non-plaque groups. The study had shown that the plaque group had lower circumferential wall shear stress, mean velocity and peak velocity compared with that of control groups. Early detection of abnormal blood flow parameters in patients with aortic atherosclerosis may help predict regions prone to plaque, allowing early intervention in patients accordingly.
