Radiolucent and radiopaque images are terms used in radiology to describe the appearance of different structures on X-ray images. Radiolucent images refer to structures or substances that allow X-rays to pass through with minimal resistance. These structures appear dark or black on the X-ray image. Examples of radiolucent structures include soft tissues, such as muscles, tendons, and organs like the lungs. On the other hand, radiopaque images refer to structures or substances that impede or block the passage of X-rays. These structures appear white or lighter on the X-ray image. Examples of radiopaque structures include bones, teeth, and certain metallic objects. It's important to note that the degree of radiolucency or radiopacity can vary depending on the density and composition of the structure or substance being imaged.
