A Computed Tomography Angiography (CTA) is an examination that uses x-rays to visualize the blood flow in arterial and venous vessels from all over the body including arteries serving the brain to those bringing blood to the lungs, kidneys, and arms and legs. CT combines the use of x-rays with computerized analysis of the images to produce a three-dimensional picture of the area being studied. The contrast material is injected intravenously before the scan. Because the contrast dye will be traveling through the patient’s blood vessels while the scan is being completed, the images produced will show blood flow. Owensboro Heart and Vascular can then use this image to more accurately diagnose and design a treatment plan to fit your unique needs. The physician can diagnose blood vessel related diseases such as aneurysms and congenital cardiovascular disease. CTAs can also help detect angiogenesis and blockages.
