What is this test?
Magnetic resonance angiography, or MRA, is an MRI-based test that creates detailed images of blood vessels in the head and neck. Intravenous contrast may be used to make the vessels easier to see.
Why might I need this test?
This test may be ordered to investigate symptoms such as severe headache, neck pain, dizziness, vision changes, weakness, or trouble speaking. It can also be used to monitor known blood-vessel conditions or evaluate blood flow before certain procedures.
How is the test performed?
You will lie on a table that moves inside an MRI scanner. The technologist may also inject contrast through a vein in your arm, and the scanner will take a series of images. The test usually requires you to remain still and may take 30 to 60 minutes.
How do I prepare for the test?
Follow the imaging center's instructions, including any fasting or medication guidance. Tell the care team if you are pregnant or breastfeeding, have kidney disease, have had an allergic reaction to MRI contrast, or have a pacemaker, implanted medical device, or other metal in your body.
Reference range
Adult males: 22-198 U/L; Females: 22-198 U/LN/A
No special preparation required. Inform provider of any chest pain or symptoms.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Abnormal findings may include narrowing or blockage of a blood vessel, an aneurysm, vessel-wall irregularity, or an abnormal connection between vessels. Depending on the location and severity, these findings may help explain symptoms or guide further evaluation and treatment. A radiologist will interpret the images in the context of your symptoms and other tests.
Short name
Head and neck MRA with IV contrast
Frequently asked questions
Is head and neck MRA the same as a routine head MRI?
