The femoral and popliteal arteries are the major arterial blood supply to the lower extremities and are a common location for atherosclerotic disease to develop. This ultimately narrows and blocks the flow of blood which carries oxygen and nutrients to the limb. The blockage most often is the result of a chronic buildup of hard fatty material into the inside lining of the arterial wall of the legs. Peripheral arterial disease (PAD) is generally associated with blocked arteries of the legs. Using CTA to Diagnose Peripheral Arterial Disease (PAD) is revolutionizing the treatment of this disease. The advance warning allows patients to seek the medical treatment and/or make the lifestyle changes that may prevent a heart attack in the future. The CT Angiography is consistently able to rule out significant narrowing of the major coronary arteries, and can also non-invasively evaluate for plaque in the artery walls, that has not yet led to a serious blackage. It is also an excellent tool for assessing patients with symptoms of numerous other conditions, such as pulmonary emboli (blood clot in the lungs) and aortic aneurysm. This CT can be used to evaluate a patient with chest pain or to clarify an uncertain stress test. The coronary CT Angiogram takes images of the heart arteries that are clear enough to see the blockage. If these arteries are blocked, and left untreated, a heart attack can occur. These images of the heart provide detailed pictures of the blood vessels that supply the heart muscle, also known as the coronary arteries. This is a special kind of scan focusing particularly on the blood vessels.
