目的比较X线与螺旋CT在气管异物诊断中的应用价值。方法选取2010年9月至2013年9月收治的68例气管异物患者作为研究对象,所有患者均行X线和螺旋CT检查诊断,对两种诊断方式的诊断价值进行比较。结果螺旋CT的正确检出率显著高于X线(P<0.05);与X线相比,螺旋CT检查能够将异物本身直接显示出来,其间接征象和X线相似。结论 X线诊断具有操作简单、检查方便的特点,螺旋CT的正确诊断率较高,两种诊断方式可互相补充,如不能及时明确异物吸入史,则可将螺旋CT作为首选的诊断方式。
Objective To compare the value of X-ray and spiral CT in the diagnosis of tracheal foreign bodies. Methods Seventy-six patients with tracheal foreign bodies admitted from September 2010 to September 2013 were selected as study subjects. All patients underwent X-ray and spiral CT examinations to compare the diagnostic value of the two diagnostic methods. Results The correct detection rate of spiral CT was significantly higher than that of X-ray (P <0.05). Compared with X-ray, spiral CT could directly display the foreign body itself, and the indirect signs were similar to X-ray. Conclusion X-ray diagnosis has the advantages of simple operation and convenient examination. The correct diagnosis rate of spiral CT is high, and the two diagnostic methods can complement each other. If the history of foreign body inhalation can not be clearly identified in time, spiral CT can be the first choice of diagnosis.
