在老年人中观察到改变的实质微结构和复杂性。如何区分健康的，预期的变化和病理学的早期迹象仍然知之甚少。对16例受试者的CT成像进行客观定量分析，比较平均肺密度、组织密度分布和组织异质性，其中8例年龄>60岁，性别和体重指数与8例年龄
Altered parenchymal microstructure and complexity have been observed in older age. How to distinguish between healthy, expected changes and early signs of pathology remains poorly understood. An objective quantitative analysis of computed tomography imaging was conducted to compare mean lung density, tissue density distributions, and tissue heterogeneity in 16 subjects, 8 aged >60 yr who were gender and body mass index matched with 8 subjects aged
