Magnetic resonance angiography: MRA; magnetic resonance imaging: MRI.
To visualize and assess internal organs/structures and blood vessels for abnormal or absent anatomical features, abscess, aneurysm, cancer or other masses, infection, or presence of disease. Used as an evaluation tool for surgical, radiation, and medical therapeutic interventions.
General: There are no food, fluid, activity, or medication restrictions unless by medical direction. MRA: Some protocols may require the patient to restrict prescribed oral iron supplements prior to the study because the iron may interfere with the study results. Restriction of food, fluids, alcohol, nicotine, and caffeine for 1 to 2 hr before the procedure may also be required in order to avoid vasoconstriction or vasodilation as well as nausea and vomiting related to anxiety while in the MRI scanner.
