Purpose of the Test

MRA (Magnetic Resonance Angiography) of the head and neck without contrast is a diagnostic test used to visualize the blood vessels in the head and neck region. It is typically ordered to evaluate for conditions such as aneurysms, arterial stenosis, vascular malformations, and other abnormalities affecting blood flow to the brain.

When this test is required

MRA of the head and neck without contrast may be requested by a doctor if a patient has symptoms or risk factors for vascular conditions affecting the head and neck region. It may also be ordered as part of a routine screening for individuals at high risk for aneurysms or other vascular diseases.

What the Test Detects

MRA of the head and neck without contrast uses magnetic resonance imaging technology to produce detailed images of the blood vessels in the head and neck. The test can visualize the blood flow in arteries and veins, and can help to detect abnormalities in the size, shape, or structure of these vessels.

Preparation for the Test

Typically, there is no special preparation required for MRA of the head and neck without contrast. Patients may be asked to remove any metal objects or jewelry before the procedure, and those with claustrophobia or anxiety may be offered medication to help them relax.

Sample Requirements

No sample is required for this test.

Additional Notes

MRA of the head and neck without contrast is a non-invasive and relatively safe diagnostic test, but it is not recommended for individuals with certain types of metallic implants or pacemakers. Patients should inform their doctor if they have any of these devices before undergoing the procedure.
