This study compares the diagnostic quality of angiograms produced with traditional contrast-enhanced (CE) MRA and the bSSFP Dixon method for non-contrast-enhanced (NCE) MRA. Eight patients with clinically indicated CE renal MRA underwent the NCE examination a week later. A vascular radiologist scored the image quality from various renal artery segments from both examinations.
