Computerized Tomography (CT) is a quick, non-invasive test that uses X-rays to capture images in sections as it moves around the body. A computer reassembles the image "slices" to produce clear and detailed images of the scanned area in a matter of seconds. The more slices a CT scanner can produce, the more information that can be captured.
CTA stands for computerized tomographic angiography and is a test that combines a conventional CT scan with the technique of angiography to create images of blood vessels in the body. Physicians may order a CTA to help diagnose a narrowing or blockage of arteries, an aneurysm, a pulmonary embolism or other vascular condition.
Advanced software enables the scanner to also be used for cardiac calcium scoring and imaging of the entire vascular system, possibly reducing the need for some other diagnostic procedures.
