Synonym(s): radiodensity

radiopacity

/ra·di·opac·i·ty/ (-pas´ĭ-te) the quality or property of obstructing the passage of radiant energy, such as x-rays, the representative areas appearing light or white on the exposed film.radiopaque´

radiopacity

[-pas′itē]
Etymology: L, radiare, to emit rays, opacus, obscure
the ability to stop or reduce the passage of x-rays. Bones have relative radiopacity and therefore display as white areas on an exposed x-ray film. Lead has marked radiopacity and therefore is widely used to shield x-ray equipment and atomic power sources. Also called radiodensity. radiopaque, adj.

ra·di·o·pac·i·ty

(rā'dē-ō-pas'i-tē)
State of being radiopaque.
Synonym(s): radiodensity.

radiopacity (rāˈ·dē·ō·pasˑ·i·tē),

n the capability of a substance to hinder or completely stop the passage of x-rays, such as lead and bones, thus producing a light image on film. Also called
radiodensity.

ra·di·o·pac·i·ty

(rā'dē-ō-pas'i-tē)
X-ray shadow of a radiopaque object.

radiopacity (rā´dēōpas´itē),

n relative term referring to the considerable attenuation of a radiographic beam produced by materials of relatively high atomic number. The image on a radiograph of such materials is relatively light because less radiation passes through, which prevents the exposure of the film in that area.

radiopacity

the quality or property of obstructing the passage of radiant energy, such as x-rays, the representative areas appearing light or white on the exposed film.
