Radiologic evaluation of foreign bodies.

Author information

Department of Radiology, Western Pennsylvania Hospital, Pittsburgh.


The correct selection of a radiologic imaging modality along with knowledge of indirect radiologic findings can help determine the presence and location of a foreign body. Plain radiographs should be the initial screening modality for a suspected foreign body. Whereas most metal and glass foreign bodies are detectable on radiographs, many foreign bodies, including wood, are not. We do not advocate using xeroradiography for the detection of foreign bodies. When a suspected superficial foreign body is not delineated on radiographs, ultrasonography should be the next modality of choice. CT should be reserved for deep foreign bodies or when foreign bodies are not seen on radiographs or ultrasonography but are suspected.
