CLINICAL MEDICINE

Detailed explanation-1: -Radiopaque agents are drugs used to help diagnose certain medical problems. They contain iodine, which blocks x-rays. Depending on how the radiopaque agent is given, it localizes or builds up in certain areas of the body. The resulting high level of iodine allows the x-rays to make a “picture” of the area.

Detailed explanation-2: -Traditionally, metals such as aluminum, stainless steel, and titanium have been used for structural components in the medical device industry. But these materials are radiopaque-that is, they obstruct x-rays.

Detailed explanation-3: -The more dense the tissue or material, the more radiation is absorbed and fewer photons reach the X-ray sensor. This translates into light or radiopaque areas on the radiograph. As a result, the radiographic appearance of tooth enamel is light. The dentin is less dense and less radiopaque than the enamel.

Detailed explanation-4: -Radiopaque volumes of material have white appearance on radiographs, compared with the relatively darker appearance of radiolucent volumes. For example, on typical radiographs, bones look white or light gray (radiopaque), whereas muscle and skin look black or dark gray, being mostly invisible (radiolucent).
