Computerized Tomography (CT) Scan

A new generation of advanced imaging technology

A cardiac computed tomography scan, commonly called a cardiac CT, uses X-rays to create detailed three-dimensional views of your heart and blood vessels.

We have one of the highest volume and most advanced cardiac imaging programs in the mid-Atlantic region. Because of this experience, we are able to quickly recognize even the most rare abnormalities, resulting in a more accurate diagnosis. Our Cardiac CT Core Lab, part of our Cardiovascular Core Laboratories provides internationally recognized expertise in interpreting and analyzing the results of these tests.

Our scanner, is faster and provides sharper and more detailed images than a traditional CT scanner. At this speed, highly accurate images of fast-moving organs like the heart can be captured. You are also exposed to lower levels of radiation during scanning.

A cardiac CT scan can detect or evaluate coronary artery disease, problems with the heart’s valves, blood clots within the heart’s chambers or tumors in or on the heart.

What to expect from a cardiac CT

Your doctor may give you a beta-blocker before the test to slow your heart so clearer pictures can be taken. You’ll lie down on a table, at which time a contrast dye will be injected into a vein in your arm. The dye highlights your blood vessels and allows for clearer pictures.

The table will be moved into the CT machine, which looks like a giant tunnel. The machine will make soft clicking or whirring sounds as it takes pictures. You may be asked to hold your breath for a few seconds. The scan should take 10 to 15 minutes, but the whole process may take up to an hour if you need to wait for the beta-blocker to take effect.

Your scan will be supervised by a physician in our Cardiac CT Lab imaging suite. Expert cardiologists, radiologists, cardiac-specialized radiology technologists, a cardiac nurse and a cardiovascular 3-D imaging technologist work together in the lab.

As with any X-ray, there is some exposure to radiation, although the levels used cardiac CTs are considered safe for adults. Tell your doctor if you’re pregnant, as it may not be safe for a developing fetus. Some people may have an allergic reaction to the contrast dye. Let your doctor know if you’re uncomfortable in tight spaces, as medication may help you relax during the test.

Once the cardiac CT is done, you should be able to go back to your normal activities. Your doctor will review the results and discuss with you what the images showed.
