X-Ray Images
X-ray uses a digital device to capture an image of the body much the way a digital camera collects an image. Unlike a camera, which uses reflected light, the x-ray image utilizes x-rays that have passed through the body to record an image.
You may be asked to remove dense metal objects such as watches, jewelry, or belt buckles that may block x-rays. Nearly all CRA x-rays are now obtained digitally which allows the image to be manipulated similar to the way a digital photograph may be manipulated on a computer. This can improve the diagnostic quality of the image and reduce the need for repeat images.
X-rays include typical imaging such as chest x-rays and bone films but also include other types of examinations such as intravenous pyelogram (IVP) and mammography. Fluoroscopic examinations such as upper G.I. series and barium enema use x-rays to obtain images while administering oral or rectal contrast agent.
