Chest x-rays uses a special type of radiation to take pictures of the lungs, heart, and the blood vessels: aorta. X-rays travels more easily through less radiologically dense tissues such as fat and muscles, and these structures display shades of gray on a radiograph.
Computed tomography scan (CT scan) is a non-invasive diagnostic imaging procedure, that is more detailed than the general X-rays. It shows the detailed images of aortic obstacles with greater clarity, and reveals more details than the regular X-ray exams. The CT scan uses a combination of sophisticated computer technology and a special X-ray equipment to produce both horizontal and vertical (cross-sectional) images of the organ.
The X-ray beam in CT moves in a circle around the body to allows many different views of the same structure or organ. The X-ray information is sent to a computer and thereby it interprets the X-ray data and displays it in a two-dimensional form on a monitor.
