Brain MRV only

Specimen Required

Fasting Required

Purpose of the Test

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

When this test is required

Brain MRV may be requested if a patient presents with symptoms such as headache, dizziness, or fainting, which may be caused by a problem with the veins in the brain. The test may also be ordered if a patient has a history of conditions that affect the veins, such as a blood clot or a clotting disorder. 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 MRV is a medical imaging test that uses magnetic fields to create images of the veins in the brain. It specifically focuses on the veins in the brain, allowing healthcare providers to evaluate the blood flow and identify any abnormalities, such as a blood clot or a narrowing of the veins.

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
