It helps doctors evaluate the structure of the heart, detect coronary artery disease, assess heart function, and identify other cardiovascular conditions.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">At <\/span><b>RS Abdi Waluyo<\/b><span style=\"font-weight: 400;\">, Cardiac CT is performed using the latest <\/span><b>Photon-Counting CT (PCCT)<\/b><span style=\"font-weight: 400;\"> technology. Unlike conventional CT scanners, Photon-Counting CT directly detects individual X-ray photons, producing exceptionally sharp images with greater detail while using lower radiation doses. This breakthrough technology allows physicians to visualize even small coronary arteries, plaques, and heart structures with remarkable precision, leading to earlier and more accurate diagnosis.<\/span><\/p>\n<hr \/>\n<h1><b>Why is Cardiac CT Performed?<\/b><\/h1>\n<p><span style=\"font-weight: 400;\">Your doctor may recommend a Cardiac CT to:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Evaluate chest pain or other symptoms that may be related to heart disease.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Detect narrowing or blockage in the coronary arteries.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Assess calcium buildup in the coronary arteries (Coronary Calcium Score).<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Evaluate congenital heart abnormalities.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Assess the anatomy of the heart before structural heart procedures or surgery.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Monitor known coronary artery disease.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Evaluate bypass grafts or coronary stents in selected patients.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Assist in planning treatment for cardiovascular conditions.<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">A Cardiac CT can often help determine whether invasive testing is necessary, allowing many patients to avoid unnecessary procedures.<\/span><\/p>\n<hr \/>\n<h1><b>Details of the Examination<\/b><\/h1>\n<p><span style=\"font-weight: 400;\">Cardiac CT with Photon-Counting CT is a fast, painless outpatient examination.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Depending on your clinical condition, the
