| 目的
对患者呼气相 HRCT 上空气潴留征的范围进行定量分析,并分析其与肺功能
试验(PFT)指标的关系。方法 55例肺弥漫性病变的患者进行吸气相、呼气相HRC
T和肺功能试验检
查,统计双肺吸-呼气相密度差值(VD)和面积缩小率(AD)、空气潴留评分值并与肺功能
试验指标进行相关性分析。结果 空气潴留征象普遍存在;双肺VD和AD、
空气潴留评分值与
肺功能试验指标显著相关(P<0.05)。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。 |

| Objective
To quantify the extension of air trapping on expiratory H
RCT of lung and correlation with (pulmonary function test) PFT results. Methods Inspiratory
and expiratory H
RCT scans were performed and studied in 55 patients with PFT results. The inspira
tory-expiratory value difference (VD), area decrease ratio (AD), air-trapping gra
ding of bilateral lungs were calculated and compared statistically with PFT inde
xes. Results Air-trapping existed commonly. There was significant
correlation be
tween VD, AD, and between air-trapping grading and PFT indexes. Conclusion
Air-trapping on e
xpiratory HRCT scan can be quantified and used to assess pulmonary function of t
he patient. |
