目的:通过肺循环时间的测定来反映COPD患者肺弥散功能的强弱.方法:对35例患者分别经640VCT进行肺循环时间测定与肺灌注显像对比分析.结果:按肺灌注受损面积小于25%的肺循环时间为12.86±2.43秒8例,受损面积25%~50%肺循环时间为17.56±2.53秒18例,受损面积大于50%肺循环时间大于22.35秒9例;结论:COPD患者由于肺泡壁的破坏引起毛细血管床的减少而血流减少,通过肺循环相对时间的测定,能够准确判定肺弥散功能的受损程度.

Objective: To reflect the strength of the lung dispersion function through the pulmonary circulation time determination of COPD patients. Methods: 35 patients by 640 respectively VCT pulmonary circulation time measurement the pulmonary perfusion imaging contrast analysis. Results: According to the pulmonary perfusion damage area was less than 25% of the pulmonary circulation time was 12.86+/-2.43 (s), 8 cases of the damaged area of 25%~50%pulmonary circulation time was 17.56+/- 2.53 (s) 18 cases, the damaged area was more than 50% pulmonary circulation time more than 22.35 (s), 9; Conclusion: Patients with COPD due to the destruction of the alveolar walls caused by capillary bed decreased blood flow was decreased, through the pulmonary circulation relative time measurement, to determine the accurate lung dispersion function of the degree of damage.
