Radiopacity

Radiopacity refers to how well a material prevents X-rays from passing through it. Materials that are very radiopaque, like bones or metal implants, appear bright white on an X-ray image because they block more X-rays. Conversely, less radiopaque materials, such as soft tissues or muscles, allow more X-rays to pass through and appear darker. This property helps doctors distinguish different structures inside the body, aiding in diagnosis and treatment planning. Essentially, radiopacity is a measure of how visible a material is on an X-ray based on its ability to absorb or block X-ray radiation.
