| Popis: | Patients with penetrating wounds with suspected foreign bodies retained in the wound are often seen in emergency departments. Imaging studies are necessary to rule out the presence of retained foreign bodies. Plain-film X-rays, however, are only useful when the foreign bodies contain radiopaque material (metal, glass, stone, and some plastics). In cases with strong diagnostic suspicion and negative plain films, other imaging tests are necessary. Ultrasonography has proven useful in the identification and location of both radiopaque and radiotransparent foreign bodies. Ultrasonography enables excellent assessment of adjacent anatomical structures (muscles, tendons, ligaments, and neurovascular structures) and of associated lesions. The different materials found in foreign bodies have characteristic ultrasonographic patterns that are useful for diagnosis. Finally, it is important to be familiar with the diagnostic pitfalls to avoid false positives. |
