CT Brain Angiography (CTA) is a specialized, non-invasive imaging technique that uses computed tomography combined with a contrast dye to create detailed, 3D images of the blood vessels in the brain. This test is primarily used to evaluate the cerebral arteries for conditions such as aneurysms, stenosis (narrowing), occlusions (blockages), arteriovenous malformations (AVMs), and other vascular abnormalities.

It helps in the diagnosis and management of strokes, hemorrhages, headaches, dizziness, and other neurological symptoms by providing clear visualization of blood vessel patency and abnormalities.

Why is CT Brain Angiography Done?

Doctors recommend this test to evaluate blood flow in the brain and identify vascular problems that may cause headaches, dizziness, or stroke-like symptoms. Key purposes include:

  1. Identifying brain aneurysms or hemorrhage

  2. Detecting blood vessel narrowing (stenosis) or blockages

  3. Monitoring post-surgical vascular conditions

  4. Assessing blood flow abnormalities

  5. Evaluating stroke and transient ischemic attacks (TIA)

How is the Procedure Performed?

The test is simple, safe, and usually completed within 15–30 minutes.

  1. A contrast dye is injected into a vein (usually in the arm).

  2. The CT scanner takes rapid X-ray images as the dye moves through the brain’s blood vessels.

  3. The system then reconstructs the images into a detailed 3D model for accurate assessment.

Patients are usually advised to stay still and may be asked to hold their breath for short moments during scanning.

Preparation Before the CT Brain Angio

  1. Fast for 3–4 hours before the scan if contrast dye is used.

  2. Inform your doctor about any allergies or previous reactions to contrast material.

  3. Remove metal objects, jewelry, or hairpins before entering the scan room.

  4. Pregnant women or those with kidney issues should discuss safety precautions with the radiologist.

Advantages of CT Brain Angiography

  1. Quick and non-invasive imaging technique

  2. High-resolution details of blood vessels

  3. Early detection of vascular diseases

  4. Useful in planning surgery or other interventions

  5. Lower risks compared to conventional angiography

Risks and Precautions

Although rare, mild side effects like allergic reactions to contrast dye or dizziness may occur. Proper hydration before and after the scan helps flush out the dye from the body effectively.

Frequently Asked Questions

The scan itself usually takes about 15-20 minutes, but the entire process may take up to 30 minutes, including preparation and contrast injection.

The procedure is generally painless. Patients may feel a brief sensation of warmth when the contrast dye is injected but should experience no other discomfort.

The scan uses a small dose of radiation and contrast dye, so there’s a slight risk of allergic reaction, particularly in patients allergic to iodine. People with kidney issues should inform their doctor due to the contrast dye.

Preparation may involve fasting for a few hours beforehand, and patients should remove any metal accessories. Notify your doctor of any known allergies or if you’re pregnant.
