WebDifferent soft tissues attenuate x-ray photons differently, depending on tissue density; the denser the tissue, the whiter (more radiopaque) the image. The range of densities, from most to least dense, is represented by metal (white, or radiopaque), bone cortex (less white), muscle and fluid (gray), fat (darker gray), and air or gas (black, or radiolucent). WebX-rays are most commonly used for swallowed foreign object cases to examine the stomach, throat and esophagus. An x-ray can also be helpful for identifying foreign objects lodged in soft tissue. Once the foreign body has been identified, it can be successfully removed by the right means. 5. Bone Injury.
