MR angiography (MRA) of the neck is non-invasive method used to evaluate neck arteries in 3D fashion and help to identify vascular abnormalities. This exam does not use radiation and may require an injection of contrast material
Patients with suspected arterial abnormalities such as:
Atherosclerotic disease in the carotid artery of the neck, which may limit blood flow to the brain and cause a stroke, dizziness or sense of imbalance.
Arterial aneurysms or dissection that may manifest by swelling o stroke
Patients with mechanically/magnetically activated devices as cardiac pacemaker, cochlear implants.
Patients with metallic foreign body in the eye.
Pregnant women in the first trimester (benefits versus risk to be assessed).
Ferromagnetic surgical clips or prosthesis
Your physician may request MRA of the brain to assess cerebral arteries.
Your physician may ask for MRA study with contrast.
No after care or precautions needed following non contrast enhanced study.
In case of contrast enhanced study drinking plenty of water is advised to help to wash out the injected IV contrast material out of your body except if you are on fluid balance for renal or cardiac condition you may consult your physician and in case of lactating mothers it is advised to escape lactation for 24 hrs after the contrast injection
