Lake Medical Imaging offers a wide range of non-invasive tests to detect heart and vascular disease to help your physician plan the best course of treatment.
Computed Tomographic Angiography (CTA) is a minimally invasive medical test that helps physicians diagnose and treat medical conditions. An angiogram uses imaging methods and, in some cases, a contrast material, to produce pictures of major blood vessels throughout the body. Physicians use this procedure to identify disease and/or aneurysms in the aorta or in other major blood vessels, as well as to detect atherosclerosic disease in the carotid artery of the neck, which may limit blood flow to the brain and cause a stroke, among other diagnoses.
Computerized Tomographic Angiography (CTA) shows clarity of blood vessels, differentiation between arteries and veins and, unlike MRA imaging, CTA can capture evidence of calcium deposits. This lightning-fast technology can replace often inaccurate stress testing and potentially dangerous catheterization for coronary disease diagnosis. In addition, patients with pacemakers, neurostimulators, ports or other internal metal fragments have an effective alternative to Magnetic Resonance Angiography.
Lake Medical Imaging’s state-of-the-art CT scanners are so fast that they perform exams in as little as 10 seconds, enabling images of even rapidly-moving organs, such as the heart and lungs. Rotations around the body every half a second create 3-D reconstruction and views at every angle.
CT Angiography is commonly used to:
- Examine pulmonary arteries in the lungs to rule out pulmonary embolism
- Evaluate renal artery stenosis
- Identify aneurysms in the aorta or other major arteries
- Identify dissection in the aorta or its major branches
- Identify a small aneurysm or arterior-venous malformation in the liver or brain
- Detect atherosclerotic disease in lower extremity arteries
- Determines degree of narrowing (stenosis) of the carotid arteries
- CTA also guides stent-grafts and provides non-invasive follow-up evaluation, which is particularly useful for renal stents
The entire test takes a matter of minutes, with practically no preparation on your part. The results are usually reviewed and a detailed report is sent to your physician. If you would like more information, or to schedule an appointment, call 352-365-0777.
