The study was performed to evaluate detection of soft-tissue foreign bodies using conventional radiography (film-screen radiography), computed radiography printed on films (computed radiography-hard copy), and computed radiography displayed on a computer workstation (computed radiography-soft copy). SUBJECTS AND METHODS. Fifteen foreign bodies of different size, shape, and composition were implanted at different locations in a fresh cadaveric hand, and images were obtained using three radiographic techniques. Images were evaluated by four boardcertified radiologists to ascertain the conspicuity of the foreign bodies with the different techniques. A subjective grade was assigned to each image in an attempt to identify the relative conspicuity of foreign bodies when imaged with the three techniques. RESULTS. Computed radiography-soft copy is the preferred imaging technique for the detection of wood and plastic foreign bodies in soft tissue regardless of the size of the wood or the plastic. No significant differences in conspicuity among the three techniques were demonstrated with glass foreign bodies. CONCLUSION. Detection of soft-tissue foreign bodies is best done using computed radiography-soft copy instead of film-screen radiography and computed radiography-hard copy imaging.

Contrast mammography to detect the uptake of iodine-containing contrast material may be enhanced by spectral modification of the x-ray beam. Luminance scatter-to-primary ratios were measured for three candidate x-ray tube anode/filter combinations (Mo/Mo, W/Ce, and Ce/Ce). Results show that scattered radiation is significant for all tubes, is lowest for the Mo/Mo system and is essentially the same for the tungsten and cerium anode systems.
