雾化吸入肺增强CT扫描初探

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＞ ００５） 。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

Enhancement CT of Lung by Atomizing Contrast Inhalation Initial Researching

Purpose To observe the enhancement CT of lung by atomizing contrast inhalation whether to improve the finding ability of bronchiectasis and measure local lung function by contrast inhalation CT.Methods There were 17 cases of patients with branchiectasis by clinical suspicious diagnosis.Plain CT scan and enhancement CT scan with ultrasound atomizing inhalation had been done successively.Comparing the finding ability of lesions with these two methods by double bland method.To measure the CT value variance after inhalation in 58 pairs of interesting areas.Results There were no more findings of lesions in CT after contrast inhalation and there were no difference of CT value between the plain CT and enhancement CT ( P >0 05) Conclusion Enhancement CT of lung by atomizing contrast inhalation can not improve the finding of bronchiectasis and can not estimate local lung function.
