Renal Artery Contrast-Free Trial
Completed
Conditions studied: Renal Artery Stenosis, Kidney Diseases, Hypertension
In brief
This study will compare the results of a clinically ordered abdominal CT angiography to a research non-contrast MR angiogram (MRA). CTA is a "gold-standard" for identifying blockages in the kidney arteries or other blood vessel problems. CTA requires radiation and contrast to obtain useful images. Conversely, the MR abdomen technique being used for the study uses no radiation or contrast and is felt to be a safer option for individuals who have kidney problems. there is benefit to establishing non-contrast MRA as a clinically accurate test.
