胸部高分辨CT在儿童慢性咳嗽的程序式诊断中的作用探讨

Evaluation the influence of HRCT in the diagnostic algorithm for chronic cough in children

目的对儿童慢性咳嗽的程序式诊断方法进行探讨。方法胸部CT检查时的定位相类似于X线片检查,比较胸部CT定位相和高分辨CT(HRCT)检查的差异。结果经胸部CT定位相明确诊断5例(7.93%),经胸部HRCT明确诊断44例(69.84%),差异具有统计学意义。结论 HRCT有助于发现慢性咳嗽儿童的肺部病变,优于胸部X线CT定位相检查。综合考虑患儿利益,建议对慢性咳嗽儿童必要时可以考虑胸部HRCT检查。

Objective To explore the diagnostic algorithm protocol for chronic cough in children. Methods CT positioning phase of the chest similar as the X-ray examination. Compare the differences between the two examinations. Results 5 cases were made a definitive diagnosis by CT positioning phase, accounted for 7.93%. And 44 cases were diagnosed by high-resolution CT, accounted for 69.84%. There was significant statistical difference between the two diagnostic results. Conclusions High-resolution CT examination helps to identify lung disease in children with chronic cough, the results was better than X-ray examination. Considering the interests of the children with chronic cough, high-resolution CT examination should be considered to choose if necessary.
