The ability of B-scan ultrasonography to detect soft tissue foreign bodies of various sizes and composition was investigated in a canine model. Foreign bodies consisting of wooden rods 0.7 mm and larger, lead-free glass rods 2.0 mm and larger, plastic rods 3.9 mm and 5.6 mm, and metal needles 0.5 mm and larger were embedded in fleshy soft tissue. All objects examined were discernible. Wood is best visualized followed by glass, plastic, and metal. Ultrasound may be a valuable noninvasive means of detecting soft tissue foreign bodies; further investigation to delineate its clinical role is warranted.
在犬类模型中研究了B超检测各种尺寸和成分的软组织异物的能力。将直径0.7毫米及以上的木棒、直径2.0毫米及以上的无铅玻璃棒、直径3.9毫米和5.6毫米的塑料棒以及直径0.5毫米及以上的金属针等异物嵌入肉质软组织中。所有检查的物体均可被识别。木材最容易被看清，其次是玻璃、塑料和金属。超声可能是检测软组织异物的一种有价值的非侵入性手段；有必要进一步研究以明确其临床作用。
