Low Dose CT Cardiac Imaging

NewYork-Presbyterian Westchester offers Low Dose cardiac computer tomographic angiography or cardiac CTA. This is the only non-invasive way to visualize the heart and identify coronary artery disease. But more importantly, the multi-detector CT scanner is capable of reducing by up to 40% of the radiation a patient is exposed to during a scan.

Cardiac CTA has the capability of determining the origin of the most dangerous causes of chest pain, including coronary artery disease, aortic abnormality or a blood clot in a pulmonary artery. Most people don’t realize that a stress test can only detect coronary artery disease that is compromising the coronary artery by 70% or greater. Most heart attacks occur from developing disease or plaque that can cause vessel narrowing of less than 50%. This is where cardiac CTA is the most sensitive and could have a significant influence in one’s heart health. When a physician suspects a medical problem that is not easily detectable with a conventional physical examination, this is the diagnostic exam of choice.
