What Is A
CTA?
3D CT Angiography otherwise known as Heart scan is a diagnostic imaging test that uses 3D CT in combination with an EKG and computer technology to create detailed images of the heart’s vessels, valves, and chambers. It can be used to diagnose a variety of cardiac issues and uncover other information about heart health including:
- Coronary artery disease.
- Enlargement or thickening of the muscle walls in the heart.
- Determine safely, rapidly, and non-invasively who is at risk for heart attacks and cardiac death, and what to do about it.
- Evaluate bypass grafts and stent patency (how well they are holding up), and not just score the calcium content of the arteries anymore.
How Is It
Done?
The procedure begins with an injection of contrast dye that is visible on CT scans. The dye allows the medical team to clearly see any potential blockages or other issues present in the patient’s coronary arteries. The CT machine will then take numerous pictures from different angles while the patient lies still on a table. The images are sent to a computer for interpretation by highly trained doctors who specialize in this procedure.
