radiolucency

noun

/ˌreɪdiəˈluːsənsi/

Definition

Radiolucency refers to the property of a material that allows the passage of radiation, making it appear dark on an X-ray film.

Examples

The dentist noted the radiolucency around the roots of the tooth in the X-ray images.
Radiolucency indicates the presence of certain types of tumors that may be less dense than surrounding tissues.
In the case of a fracture, the radiolucency can suggest that the bone has lost density in that area.

Meaning

The term is commonly used in radiology to describe tissues or substances that do not absorb radiation, therefore allowing rays to pass through and creating a shadow effect on imaging.
