Cardiac CT Scan

What to Expect

A computed tomography (CT) scan of your heart creates detailed pictures of your heart and its vessels. This scan uses X-rays to create 3-D images. When it’s done with contrast (X-ray) dye so your doctor can see the vessels that bring blood to your heart, it is called a CAT scan angiogram or CTA.

During a heart CT, you will lie on a table that slides into a CT scanner. Electrodes will be placed on your chest to measure your heart’s electrical activity.

Once you’re inside the CT scanner, you will need to remain very still. The X-ray will rotate around your body. You might be asked to hold your breath for short periods.

If you have any concerns about being in the CT scanner, speak up. Your heart care team at Baystate wants you to be comfortable and relaxed so that you can lie still.

This test should only take about 10 minutes. Depending on your symptoms and diagnosis, you will be able to go home afterward.
