Background:

CCTA is a common way to evaluate coronary artery disease. It stands for coronary computed tomography angiography. It uses scanning to look at the arteries that supply blood to the heart. It is noninvasive, widely available, and generally accurate. But it does expose people to radiation. Exposure to high amounts of radiation can increase a person s risk of getting cancer. Researchers want to learn more about the relationship between CCTA and radiation exposure.

Objective:

To see how much radiation is used to take pictures of the heart and how measures to reduce radiation are used around the world.

Eligibility:

People ages 18 years and older who need a computed tomography (CT) scan of the heart

Design:

Participants will be screened with a review of their medical records.

Participants may have a pregnancy test.

Participants will have the scheduled scan. Small, sticky discs will be placed on the chest. A small tube will be placed into a vein in the arm. A contrast material (dye) will be given through it. Participants will lie on the CT scanning table.

A CCTA scan usually takes about 15 minutes if the heart rate is slow and steady.
