- Neuroradiologists also perform MRA to detect a brain aneurysm, which is an abnormal widening or ballooning of a cerebral vessel.
- Brain aneurysms occur when an injury or congenital defect weakens the wall of the vessel.
- Aneurysms are particularly dangerous because they can burst and cause potentially fatal bleeding.
Subsequently, How long does a brain MRA take? The MRA scan may take between 1 to 2 hours, depending on the body area or part that is undergoing the test. A special intravenous (IV) dye called “contrast” is frequently used for the MRA test to help parts of the body show up better during the scan.
Can you drive after an MRA scan? Unless you had medicine to help you relax, you can usually get back to your normal activities. If you had the medication then you may need to rest. You won’t be able to drive until it wears off. Your doctor will call you with the results of the exam.
Yet, Can an MRA detect a brain tumor? It can measure the metabolites (chemical changes) inside the tumor. Sometimes, this test is used to figure out if a growth is an active tumor or a mass of scar tissue. Magnetic resonance angiography (MRA) and magnetic resonance venography (MRV).
Is MRA safe? This reaction can affect your skin, joints, liver, and lungs. If you have a history of kidney disease, your healthcare provider may decide that an MRA using contrast is not safe for you. But an MRA without injected contrast won’t harm your kidneys, even if you have kidney disease.

What is the difference between an MRI and an MRA of the brain?
MRI: What’s the difference? MRI, or magnetic resonance imaging, uses radio waves, a magnetic field, and a computer to create images of the inside of the body. MRA, or magnetic resonance angiography — sometimes called a magnetic resonance angiogram — is a magnetic resonance procedure that zeroes in on the blood vessels.
How long does it take to get MRA results?
The radiologist may talk to you about the results of your MRA right after the test. Complete results are usually ready for your doctor in 1 to 2 days. Normal: The blood vessels look normal and the blood flow through them is not reduced or stopped.

Be sure to notify your technologist of any medication you’ve taken prior to your MRI. Also, to avoid potential aspiration issues while lying flat, you’ll also want to avoid eating and drinking for at least two hours before your scan.
