简介：鱼骨是成人最常见的呼吸消化道异物。放射学研究，往往下令诊断，有可疑utility.METHODS：喉镜，从10个鱼类的骨头被放置在不同的位置在一个人的头部和颈部尸体标本。结果：X线平片诊断乳腺癌的敏感性为39%，特异性为72%。烹饪不会显著改变射线不透性。鱼的种类影响软组织中的可见度，而不相关的每个物种的特征光密度。最容易识别的是与山谷中的薄膜正交放置的骨。CT扫描正确识别9 10 bones.CONCLUSIONS：平片造影显示软组织中的鱼骨异物较差;可视性随鱼的种类、位置和方向而变化。CT是放射学诊断鱼骨嵌塞的首选检查方法。
INTRODUCTION: Fish bones are the most common aerodigestive foreign bodies in adults. Radiographic studies, often ordered for diagnosis, have questionable utility.METHODS: With a laryngoscope, bones from 10 fish species were placed in a variety of positions in a human head and neck cadaver specimen. Plain films and CT scans were obtained and evaluated by blinded readers.RESULTS: Plain radiography exhibited a sensitivity and specificity of 39% and 72%. Cooking did not grossly change radio-opacity. The species of fish affected visibility in soft tissue, without correlation to the characteristic optical density of each species. Bones placed orthogonal to the film in the vallecula were most readily identified. CT scanning correctly identified 9 of 10 bones.CONCLUSIONS: Plain radiography poorly visualizes fish bone foreign bodies in soft tissue; visibility varied with fish species, location, and orientation. CT is the test of choice to radiographically diagnose fish bone impactions.
