Procedure Information

What is a CTA Scan of the Head?

A CTA scan of the head is a medical procedure that uses a computed tomography (CT) scanner. The machine takes images of the brain in cross-sectional layers through X-rays.

Why Would I Get a CTA Scan of the Head?

A CTA scan of the head is used when doctors need a more detailed image of the brain than that of a standard X-ray or MRI. It can be used to diagnose conditions such as aneurysms, stroke, hemorrhage, and tumor.

What Happens During a CTA Scan of the Head?

The procedure is done in an imaging center or hospital. Before the scan, the patient is asked to stay still and avoid talking or moving. The patient will lie on a moveable table that slides into a large doughnut-shaped scanner. The scan will not cause pain and only recorded data is used to generate images of the brain.

What to Expect After a CTA Scan of the Head?

After the procedure, the doctor reviews the results and discusses with the patient any abnormal results. The patient may experience mild discomfort where the IV was inserted. Otherwise, no recovery time or period is usually needed.

Conclusion

A CTA scan of the head is a medical procedure used to identify abnormalities in the brain. The procedure is painless and requires no recovery period. The scan results are then shared with the patient.
