目的 探讨超声在中央型肺癌并阻塞性肺不张的诊断价值。方法 随机选择 75 0例胸科患者行双盲同期胸部常规X线胸片、CT和超声检查。将三种方法对中央型肺癌并阻塞性肺不张病例的检出结果进行前瞻性比较。结果 超声、胸片对肺不张敏感性的比较以及超声、胸片、CT对不张肺内肿块显示和界定的比较差异均有显著性意义 (P <0 .0 0 5 ) ,对肿大淋巴结的检出超声不如CT。结论 中央型肺癌并阻塞性肺不张时 ,超声作为一种检查方法可以弥补X线胸片和CT的某些不足
Objective To explore the diagnostic value of ultrasound in central lung cancer and obstructive atelectasis. Methods A total of 750 chest patients were randomly selected for double-blind chest X-ray, CT and ultrasonography. The three methods were used to prospectively compare the detection results of central lung cancer and obstructive atelectasis. RESULTS: The comparison of the sensitivity of ultrasound and chest radiographs to the atelectasis and the differences in the display and definition of atelectasis between the ultrasound, chest radiograph, and CT showed significant differences (P < 0.05). Ultrasound detection of lymph nodes is not as good as CT. Conclusion When central lung cancer is obstructive atelectasis, ultrasound as an examination method can make up for some insufficiency of X-ray and CT.
