What are the risks associated with CCTA?
CTCA can cause allergic reactions due to the use of contrast agents, and can affect renal function, especially in patients with chronic kidney disease. The American Heart Association, Society of Cardiovascular Computed Tomography, and American Society of Nuclear Cardiology recommend dose-reduction techniques to minimize radiation exposure whenever possible. Care should be taken when exposing low-risk patients to ionizing radiation, particularly in younger patients, as the projected cancer risk is elevated.
