Advanced cardiac imaging shows how your heart is functioning in real time. It combines two tests: cardiac CT (computed tomography) and cardiac MRI (magnetic resonance imaging).

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.
