The x-ray has been called one of the most significant advances in all of medical history. It is used in many different ways in medical diagnosis. An x-ray image is produced when a small amount of radiation passes through the body. The ability of x-rays to penetrate tissues and bones varies according to the tissue's composition and mass. Bone, which contains calcium, does not let much radiation through and results in white images on the scan. The lungs, which are filled with air, allow nearly all x-rays to pass through the body resulting in a black image.
Fluoroscopy studies use x-rays to examine soft tissue organs such as the stomach, liver and intestines which all have a density that normally gives the radiology image an external outline but does not show the inner parts of these structures. By introducing a contrast material such as barium (which can be swallowed or given as an enema), full views of these organs can be seen. Air and barium can be used together as a "double contrast" study for even greater detail.
