Brain MRA only

Specimen Required

Fasting Required

Purpose of the Test

A brain MRA may be ordered to evaluate the blood vessels in the brain and diagnose conditions that affect the blood flow, such as an aneurysm, a blood clot, or a narrowing of the blood vessels. It can also help identify any abnormalities or malformations of the blood vessels in the brain.

When this test is required

Brain MRA may be requested if a patient presents with symptoms such as headache, dizziness, or fainting, which may be caused by a problem with the blood vessels in the brain. The test may also be ordered if a patient has a history of conditions that affect the blood vessels, such as high blood pressure or atherosclerosis. In some cases, it may be used as a screening tool for individuals at high risk of developing a stroke.

What the Test Detects

Brain MRA is a medical imaging test that produces detailed images of the blood vessels in the brain using magnetic fields and radio waves. It specifically focuses on the arteries and veins of the brain, allowing healthcare providers to evaluate the blood flow and identify any abnormalities, such as an aneurysm or a narrowing of the blood vessels.

Preparation for the Test

Patients should inform their healthcare provider of any medical conditions, allergies, or implanted devices that may interfere with the test. They should also remove any metal objects, such as jewelry or clothing with metal zippers or buttons, and change into a hospital gown before the test. Patients should follow any instructions provided by their healthcare provider regarding fasting or other preparation for the test. Depending on the type of contrast material used, patients may be asked to avoid eating or drinking for a few hours before the test. It is important to inform your healthcare provider if you have any kidney disease, as some types of contrast material can affect kidney function.

Sample Requirements
