radio-opaque
Stops radiation passage
Radio-opaque describes materials that block X-rays or other radiation, appearing white or bright on radiographic images.
Bones are naturally radio-opaque; contrast dyes are injected to make blood vessels and organs radio-opaque for imaging.
The opposite is radiolucent—transparent to radiation.
Also spelled radiopaque.
