An in vitro study comparing two different film-screen combinations in the detection of impacted fish bones

Br J Radiol. 1998 Sep;71(849):930-3. doi: 10.1259/bjr.71.849.10195007.

Abstract

Dried fish bones from eight species of Malaysian fish were placed in an animal cadaver at four sites (tonsil, valleculae, larynx and oesophagus) and radiographed using a double and a single film-screen combination. The use of the single film-screen combination resulted in visibility of all fish bones placed in the larynx, two of which were not visible on the double film-screen combination. There was a 50% increase of the visibility of the fish bones in the oesophagus using the single film-screen combination. The difference in dose and cost between the two different film-screen combinations was not significant.
