A Computed Tomography scan, or CT scan, also known as a CAT scan, is a non-invasive diagnostic test that uses x-rays to diagnose disease or injury to bones, as well as soft tissues inside your body, like your heart and blood vessels.
To perform a CT scan, an x-ray machine rotates around and emits a beam of x-rays as you are moved through the machine. The result is a series of cross-sectional images, or “slices”, which can be stacked together to create a three-dimensional model of the structures inside of your body.
A Coronary CT Angiogram, or CCTA, is a kind of CT scan that uses a contrast dye to show how well blood flows through the vessels that supply your heart. The details and effects of any contrast dye will be discussed by your healthcare team.
The contrast dye is injected into a vein in your arm, travels to your heart, and allows your heart and blood vessels to be clearly seen.
The information from a CT scan helps your physician choose an appropriate treatment. Ask your healthcare team for more details.
