X-ray Radiography
How does it work?
Have a shorter wavelength than visible light and can penetrate body tissues. When a certain part of the body is x-rayed, dense tissues, such as bones, absorb the rays and appear as bright areas on the developed film, called radiography. Soft tissues appear in shade of gray. X-rays are commonly used to diagnose problems or disease involving teeth, bones, breasts, and between adjacent soft tissues of the same density, a doctor may inject radiopaque dye into the patient's blood stream to enhance the contrast. Nowadays, X-rays are often digitized and viewed on a computer screen.
Risks: there is a slight chance of damage to cells and tissues, but the risk is usually very low compared with the benefits. * Women who may pregnant should inform their doctor before they submit to an X-ray. Contrast agents, such as iodine, may cause allergic reactions. So inform your doctor or technician if you have any allergies to iodine and to seafood which contains this element.
Benefits: X- ray imaging is fast, generally painless, relatively inexpensive, and quite easy to perform. Hence it is particularly useful in such areas as mammography and emergence diagnosis. No radiation remains in the body after the X- ray is administered, and usually there are no side effects.
