HU distribution for pulmonary gas volume map and blood volume maps, for the whole study population (n = 60 patients). Above: the HU distribution for pulmonary gas volume maps in the whole lung parenchyma; middle: HU distribution for pulmonary blood volume maps in the whole lung parenchyma; below: HU distribution for pulmonary blood volume maps in the hypoinflated lung parenchyma. x-axis: HU values. y-axis: percent of voxels compared to the total amount of voxels. Values represented as mean ± standard deviation (SD) or percent
