Cardiac Computed Tomography for Heart Chamber, Coronary Artery, and Valvular Assessment
This radiation-based X-ray computed tomography protocol generates high-resolution cross-sectional images of the entire cardiovascular system, including all four heart chambers, atrioventricular and semilunar valves, native and surgical bypass graft coronary arteries, cardiac veins, and associated cardiac lymphatic vessels. No iodinated contrast agent is administered for this specific cardiac CT protocol, making it appropriate for patients with contrast allergies, reduced kidney function, or other contraindications to contrast administration. Clinical use cases for this exam include screening for coronary artery calcification, evaluating congenital heart defects, assessing abnormal cardiac chamber enlargement, detecting structural valvular abnormalities, and confirming patency of post-surgical coronary bypass grafts.
This low-dose non-contrast cardiac CT uses X-ray radiation to capture detailed images of the heart, coronary arteries, heart valves, and related cardiovascular structures to diagnose a wide range of cardiac and vascular abnormalities.
