The blood flow volume within the visceral arteries were measured and compared between pre-and post-EVAR conditions using 4DFlow MRI. The maximum systolic flow volume ratio in the SMA to that of the aorta showed significant increase after EVAR. 4DFlow might be useful for evaluation of the blood flow dynamics of the aorta and visceral arteries in pre- and post-EVAR condition.
