This study aims to determine the effects of intravascular contrast agent on radially encoded velocity mapping MRI on the quality of visualization of the portal venous vasculature. While imaging without a contrast agent provides good image quality, examination of vessel signal and diagnostic quality of vasculature in derived angiograms from human volunteer after contrast administration shows greatly improved image quality and visualization of distal branches of the portal vasculature.
