General Principles Of X-Ray Contrast Media

Open Access
Chapter

Abstract

Contrast in an X-ray image is brought about by differences in absorption of X-rays by the tissues being irradiated. Absorption is dependent on the atomic number of the atoms present in the molecules, the concentration of these molecules and the thickness of the irradiated slice. When a chest radiograph is obtained, the bones, the aeriferous lungs, the heart and other tissues provide adequate natural contrast.
