Heart to Heart: Exploring Cardiac CT
Abstract:
Cardiac CT, or coronary CT, is a medical imaging technique that involves injecting iodine contrast agents into blood vessels to visualize the heart’s coronary arteries. Cardiovascular specialists utilize these images to diagnose coronary artery blockages and assess blood flow velocity. Prior to the examination, patients are required to maintain a stable heart rate, typically not exceeding 60 beats per minute. Medications such as β-receptor blockers and nitroglycerin may be administered to reduce heart rate if necessary. This technology offers rapid imaging, minimal side effects, and low rates of false negatives and false positives.
