Fish bones are the most common aerodigestive foreign bodies in adults. Radiographic studies, often ordered for diagnosis, have questionable utility.
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.
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.
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.
鱼骨是成人气道消化道中最常见的异物。常用于诊断的影像学检查，其效用存疑。
使用喉镜将10种鱼类的骨头放置在人体头颈部尸体标本的不同位置。获取平片和CT扫描图像，并由不知情的阅片者进行评估。
平片的敏感性和特异性分别为39%和72%。烹饪并未显著改变射线不透性。鱼的种类会影响在软组织中的可见性，与每种鱼的特征性光学密度无关。位于会厌谷且与胶片垂直的骨头最容易被识别。CT扫描正确识别出了10根骨头中的9根。
平片对软组织中鱼骨异物的显影效果不佳；可见性因鱼的种类、位置和方向而异。CT是影像学诊断鱼骨嵌塞的首选检查。
