Diagnosing Using Cardiac CT

If you have signs of heart disease, your doctor will likely recommend an EKG/ECG (electrocardiogram) and blood work as a first step toward diagnosis. Depending on the results, you may need to have advanced cardiac imaging CT. This test provides multiple images of your heart at different angles to show:

  • How your heart pumps
  • Your heart’s structure
  • Damage, including scarring
  • Heart defects and other problems
  • Fluid in the sac surrounding the heart

Imaging results help diagnose cardiology conditions including:


What Happens During Advanced Cardiac Imaging?

CT scanners are typically big machines with a large opening in the middle. You will lie on a narrow table that slides into the machine. The radiology team may give you a sedative if you think you will be anxious during the test or have a history of claustrophobia.


A CT scan usually lasts less than 30 minutes. It is a lot like an MRI. However, a CT scan uses low levels of ionizing radiation to obtain images. These levels are slightly higher than an X-ray. Pregnant women may need an alternate test.

Contrast Dye or Medium

Your cardiologist can track how blood flows through your heart and blood vessels by using a contrast dye, or contrast medium, during your CT. Tell your health care provider if you have kidney problems or have ever had a reaction to dye or contrast. You may be told to avoid procedures using iodine-based dyes.

It’s not unusual to have an overall warm flushing, a slight metallic taste in your mouth, or a slight burning sensation at the injection site as the dye enters your body. These sensations usually last only a few seconds.
