据报道，慢性阻塞性肺疾病 (COPD) 患者胸部 X 射线计算机断层扫描图像的低衰减区域 (LAA) 增加反映了病理性肺气肿的发展，我们检查了 COPD 患者和健康受试者中 LAA 簇的统计特性。在 COPD 患者中，LAA 占据肺野的百分比 (LAA%) 范围为 2.6 至 67.6。相比之下，LAA% 始终
Increases in the low attenuation areas (LAA) of chest x-ray computed tomography images in patients with chronic obstructive pulmonary disease (COPD) have been reported to reflect the development of pathological emphysema, we examined the statistical properties of LAA clusters in COPD patients and in healthy subjects. In COPD patients, the percentage of the lung field occupied by LAAs (LAA%) ranged from 2.6 to 67.6. In contrast, LAA% was always
