Xray, CT Scan, MRI


Physicians often need to recognize abnormalities going on in body tissues and organs to diagnose any specific diseases or not at all.These abnormalities are seen in the form of images,there are different imaging techniques used today,the most common one is a radiograph(X ray film) which provides a two dimensional image of the interior of the body.
To produce such a radiography a single barrage of X ray is passed through the body and exposes the film on the radiograph(or flouroscent screen) placed on the opposite side.Tissues having different densities show up as images of differing densities on the radiograph i.e. x rays have their nature of being absorbed to various degrees as through body tissues depending on the density of them.There are 4 fundamental radiographic densities which produce natural radiograph contrast on an X ray film.See how they appear on radiograph (or called flouroscent screen).
