Purpose of the Test

The MRV Brain Without Contrast is typically ordered to evaluate the veins in the brain for conditions such as thrombosis, stenosis, or other abnormalities. It can also help in the diagnosis and treatment planning of conditions such as cerebral venous sinus thrombosis, intracranial hypertension, and other vascular diseases.

When this test is required

The test is typically requested by a doctor when there is a suspicion of cerebrovascular disease, such as blood clots or stenosis, or when a patient has symptoms that suggest a problem with the veins in the brain.

What the Test Detects

The MRV Brain Without Contrast is a non-invasive imaging test that uses a powerful magnet and radio waves to create detailed images of the veins in the brain. The test does not involve the injection of contrast dye, making it safer for patients with allergies or kidney problems.

Preparation for the Test

Patients may be asked to avoid eating or drinking for a few hours before the test and to inform their doctor and the imaging technician of any allergies, medical conditions, or medications they are taking. Patients with certain health conditions or implanted medical devices may need to take special precautions before the test.

Sample Requirements

No sample is required for this test.

Additional Notes

MRV Brain Without Contrast is generally considered safe, but it may carry some risks, particularly for patients with certain health conditions or implanted medical devices. Patients should inform their doctor and the imaging technician if they have any concerns or health conditions that may affect the test. The test is painless and non-invasive, and patients can usually return to their normal activities immediately after the procedure.
