Penetrating injuries: how easy is it to see glass (and plastic) on radiographs?

The radiopacity of objects commonly associated with penetrating wounds and made from modern glass was assessed. It is concluded that all glass fragments should be detected because they are all radiopaque. Occasionally thin slivers of glass may be difficult to detect, but should be visualised with good radiography and careful scrutiny. Plastic from the housing of motor vehicle lamps is not radiopaque.
