定量CT在肺气肿形态学中的临床应用研究

Clinical Applications of Quantitative CT in the Morphology of Pulmonary Emphysema

目的探讨多层螺旋CT定量分析指标在肺气肿形态学评估中的应用价值.方法正常对照组60例,肺气肿组33例,深吸气状态下经256层螺旋CT扫描全肺,图像传至EBW后处理工作站,分别测定右上肺密度值、左上肺密度值、右下肺密度值、左下肺密度值、右上肺最大横径、右上肺最大纵径、右肺最大横径、右肺最大纵径、全肺横径、全肺容积、右肺容积、右上肺容积12项形态学定量指标(P<0.05).结果正常对照组与肺气肿组在肺形态学各项定量指标上差异均有统计学意义.结论应用多层螺旋CT定量分析指标对肺气肿形态学评估具有较高的临床应用价值.

Objective To investigate the value of quantitative indicators of multislice CT in the morphological evaluation of the emphysema.Methods Cases being studied were divided into the normal control group(60 cases) and thd pulmonary emphysema group(33 cases).Through the 256 total lung spiral CT scan in deep breath state,the images were sent to EBW post-processing workstation.12 morphological quantitative indicators were separately measured,namely,upper right lung density value,upper left lung density,lung density values at the lower right,lower left lung density value,the maximum transverse diameter of right lung,right lung maximum longitudinal diameter,maximum transverse diameter,maximum longitudinal diameter right lung,right lung pneumonectomy in transverse diameter,total lung capacity upper right lung and right lung volume(P<0.05).Results In comparison of the results of the normal control group with those of the pulmonary emphysema group,there were statistically significant differences in morphology quantitative indicators.Conclusion The evaluation of the morphotogy of pulmonary emphysema with the quantiative index of multislice CT is of great value in clinical diagnosis.
