Association between the Histological SA/V and CT Median Lung Density. There is a significant association between the SA/V (cm2/cm3) measured histologically and the CT median lung density (g/ml) (r = 0.82, p < 0.0001). All subjects are shown using different symbols. Data point A and B refer to samples with comparable SA/V value but very different CT density measurement (sample A: SA/V = 247 cm2/cm3, CT density = 0.14 g/ml; sample B: SA/V = 258 cm2/cm3, CT density = 0.24 g/ml). A and B refer to the same samples in Figure 2, 3, and 5.
