X-rays are used for a variety of purposes, including the diagnosis of tumors. The X-ray beams pass through the body in different amounts depending on the part of the body subject to the X-ray. A number of factors determine the degree of light and darkness in an image. An X-ray's ability to penetrate tissue depends on the amount of X-rays that are absorbed. Blood, skin, fat, and muscle appear dark gray on the film due to the soft tissues in the body that allow X-rays to pass through. Bones and tumors, denser than soft tissue, allow fewer X-rays to pass through and appear white and are effectively identified on X-rays. X-rays are available at Mosaic Diagnostic Imaging.
