CT and 3D Subtraction Angiography
Providers: Rostomily, Robert C., Sekhar, Laligam N. Last Updated: Friday, June 29, 2007


(CTA) Computed Tomography Angiography


Computed Tomography Angiography (CTA) is a safe outpatient procedure that helps locate and capture images of an aneurysm within the brain. This technology uses specially designed x-rays and intravenous dyes or contrast agents to see the detailed anatomy of the blood vessels throughout the body.

CTA is a less invasive and a more patient-friendly procedure than standard catheter angiography which requires placing a catheter into an artery close to the area being examined. Another benefit with CTA is that the contrast agent is injected into a vein instead of an artery (as in standard catheter angiography). Using the vein is technically less difficult and has a very low risk of complications. As a result, the patients typically leave immediately following the procedure and can resume normal activities.

3-Digital Subtraction Angiography

3-Dimensional imaging allows us to consistently obtain high-quality images, which helps us formulate an accurate and definitive diagnosis of intracranial aneurysms.

Subtraction angiography refers to the process of removing or subtracting objects from an image that may be obstructing the area we are most interested in viewing. For example, if we want to study blood vessels, 3D imaging will allow us to remove other structures in the image so we may view the vessels better. 

This procedure is considered to be as reliable and as safe as conventional angiography. It also reduces procedural time and decreases the need for the injection of a contrast agent.
