摘要:

目的 通过对比CT的肺容量测算结果与常规肺功能检查结果之间的相关性,评估CT测量肺容量法的可靠性和临床意义。方法 选取首都医科大学附属北京儿童医院胸外科入院治疗的共计49例漏斗胸患者,术前行肺功能检查和CT检查。应用手绘-分层测量求和法测量患者肺容量并计算其与预计值之间比例。将结果与患者常规肺功能结果进行对比。结果 基于CT肺容量结果平均值低于肺功能检查结果,但与常规肺功能结果的相关性具有统计学意义:最大肺活量(maximal ventilatory capacity, VCmax)(P<0.001)、用力肺活量(forced vital capacity,FVC)(P<0.001)、肺总量(total lung capacity,TLC)(P<0.001);基于CT的肺容量实测值/预计值比例与肺功能结果相关性均有统计学意义: VCmax%(P<0.001)、FVC%(P<0.001)、TLC%(P<0.001)。结论 CT测算的肺容积结果与常规肺功能结果高度相关,CT肺容积测算法可作为临床评估漏斗胸患者肺脏容积的一种有效方法。

Abstract:

Objective To access the reliability of CT-based pulmonary volumetric evaluation by analyzing the correlation between lung volume calculated by CT-based pulmonary volumetric evaluation method and pulmonary function test(PFT) results. Methods This study enrolled 49 patients with pectus excavatum seen in Beijing Children's Hospital. All patients had CT scan and pulmonary function test data. The CT-scan data were used to calculate lung's volume by handdrawn-layers summation method. The lung volume and PFT result were compared. Results The lung volume calculated by CT-based pulmonary volumetric evaluation underestimated from the PFT result of VCmax, FVC and TLC. However, the correlation between lung's volume and PFT result of VCmax(P<0.001), FVC(P<0.001), TLC(P<0.001) was significant. The correlation between value of actuality/anticipated between lung volume and PFT results was also significant. Conclusion The lung volume calculated by CT-based pulmonary volumetric evaluation is significantly correlated with PFT results and this method is a useful way to evaluate the lung volume in clinical practice.
