CT Angiography
What is CT Angiography?
CT Angiography (CTA) is an outpatient procedure that uses specially designed x-rays and intravenous contrast to see the detailed anatomy of the blood vessels throughout the body. It is most frequently utilized in the evaluation of arteries in the head, neck, chest, abdomen and legs.
Why is CT Angiography an excellent alternative to Catheter Angiography?
While standard catheter angiography is still considered highly accurate for diagnosing arterial disease, it does require arterial access with catheter placement with slight risk as well as post-procedural recovery for up to six hours. Compared to catheter angiography, CTA is a less invasive and more patient-friendly procedure. Although contrast is injected through an artery in catheter angiography, CTA contrast is injected into an arm vein and has a very low risk of complications. As a result, patients typically leave immediately following the procedure and can resume normal activities.
How is the procedure performed?
After obtaining IV access, you will be placed on the CT scanning table and given intravenous contrast while the CT scanner acquires pictures of the area of interest. Most people experience a temporary warming sensation while the contrast is given which dissipates rapidly. The IV is removed and your scan is complete. The real work of CTA comes after the images are acquired, when our radiologists utilize powerful 3D computer workstations to process the images and evaluate the arteries and surrounding structures.
