Purpose of the Test

MRA (Magnetic Resonance Angiography) of the brain with contrast is a diagnostic imaging test that can be used to evaluate blood vessels in the brain. It is typically ordered to diagnose conditions that affect blood flow to the brain, such as aneurysms, arteriovenous malformations (AVMs), or stroke.

When this test is required

An MRA of the brain with contrast may be requested by a doctor if a patient is experiencing symptoms such as headaches, dizziness, or confusion, or if they have a known or suspected condition that affects blood flow to the brain.

What the Test Detects

The MRA of the brain with contrast is a diagnostic imaging test that uses a magnetic field and radio waves to produce detailed images of blood vessels in the brain. The test can help diagnose conditions such as aneurysms, AVMs, or stroke.

Preparation for the Test

Before the test, patients may be asked to avoid eating or drinking for a few hours to ensure a clear image of the blood vessels. Additionally, patients may be asked to remove all metal objects from their body, as these can interfere with the magnetic field of the machine. Patients should also inform their doctor if they have any allergies or a history of kidney problems, as contrast material is used in the test.

Sample Requirements

No sample is required for this test.

Additional Notes

The MRA of the brain with contrast is a safe and noninvasive test, but patients with certain medical conditions, such as kidney problems or allergies, may not be able to undergo the test with contrast material. Additionally, patients who experience claustrophobia or anxiety in enclosed spaces may need to receive medication or other accommodations before undergoing an MRA.
