Prospective Multicenter Registry On Radiation Dose Estimates of Cardiac CT Angiography in Daily Practice in 2017 (PROTECTIONVI)

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.

Cardiac CT angiography is a commonly used test to take detailed pictures of the heart to
diagnose heart disease; however, it is associated with radiation exposure. Several
technological advances in both scanner hardware and software are now available to reduce the
radiation exposure to patients. The purpose of this study is to evaluate the worldwide usage
of these radiation dose saving strategies in daily practice and analyze their effect on image
quality.
