目的 探讨雾化吸入肺增强CT 扫描方法能否提高CT 对支气管扩张症的检出率并判断局部肺功能。方法 收集临床拟诊支气管扩张症17 例,分别做CT 平扫和超声雾化增强扫描,用双盲法比较病变检出情况;并配对测量58 对兴趣区增强前与增强后5 分钟及10 分钟的CT值变化情况。结果 病变显示没有明显增多,肺实质增强前后CT 值的变化无显著性差异( P> 005) 。结论 超声雾化肺CT 增强扫描,不能提高对支气管扩张病变的检出率,不能判断局部肺功能
Objective To investigate whether atomizing inhalation lung enhanced CT scanning can improve the detection rate of bronchiectasis and judge the local pulmonary function. Methods Twenty-seven cases of suspected bronchiectasis were collected and examined by CT plain scan and ultrasonic nebulization enhancement respectively. The lesion was detected by double-blind method and matched with 58 pairs of pre-enhancement and enhancement areas of 5 minutes and 10 minutes CT value changes. Results showed no significant increase in lesion, CT changes before and after the lung parenchyma showed no significant difference (P> 0 05). Conclusions Ultrasound nebulized pulmonary CT enhanced scan can not improve the detection rate of bronchiectasis, can not determine the local pulmonary function
