1·VD and AR of bilateral lungs and air trapping score were statistically correlated with PFT results.

双肺VD、双肺AR、空气潴留评分值与肺功能试验的结果存在显著性相关。

2·Therefore, they can be demonstrated only by mass effect on adjacent tissues or distal air trapping.

因此，我们只能通过对邻近组织的推移或远端的空气潴留来推测异物。

3·Results Expiratory scans showed evidence of air trapping, when inspiratory scan and PFTs were normal.

结果病例组在呼气末图像上发现有空气残留，而吸气末正常。

4·Conclusion Air trapping on expiratory HRCT scan can be quantified and used to assess pulmonary function of the patient.

结论呼气相hrct上的空气潴留征可以定量分析，能够反映患者的肺功能状况。

5·Conclusions: Postexpiratory HRCT can be used to evaluate air trapping in patients with OLD, and be useful in the diagnosis of these diseases.

结论：呼气末HRCT可用于评估old患者肺残气量并可诊断这类疾病。

6·The incidence of centrilobular emphysema, paraseptal emphysema and air trapping in heavy smokers was higher than that in light ones ( P< 0.05).

小叶中心型肺气肿、间隔旁型肺气肿和空气潴留在重度吸烟组的发生率高于轻度吸烟组（P< 0 .0 5 ）。

7·Objective To assess the findings on inspiratory and expiratory lung HRCT in COPD and to quantify the extension of air trapping on expiratory HRCT.

目的分析慢性阻塞性肺疾病（COPD）患者吸气相和呼气相高分辨率CT（HRCT）表现，对呼气相HRCT上的空气潴留征进行定量分析。

8·Patchy lobular lucency and air trapping may also be seen, and is characteristic of hypersensitivity pneumonitis, reflecting the presence of bronchiolitis.

还可见小叶性透亮区和空气潴留，是HP的特征性表现，为细支气管炎表现。

9·Air trapping secondary to bronchial or bronchiolar obstruction may produce focal zones of decreased attenuation, an appearance that can be enhanced by using expiratory ct.

继发于支气管和细支气管阻塞的空气潴留可产生局部低衰减带，后者应用呼气相ct可增强其表现。

10·Air is drawn in via the mouth and the nose, the latter acting as an air filter by trapping dust particles on its hairs.

空气通过口腔和鼻孔被吸入，其中鼻孔可以通过鼻毛捕获空气中的尘埃而起到过滤空气的作用。
