Fractional content of air in lungs measured by micro-CT in control and bleomycin-exposed mice at 1 and 3 weeks

	Fraction of Air Comprising Observed Lung Volume
	End Inspiration	End Exhalation
Control (1 wk)	66.6±3.2%	35.7±6.1%
Bleomycin (1 wk)	52.2±8.8%*	23.3±7.9%†
Control (3 wk)	63.0±7.1%	33.9±7.9%
Bleomycin (3 wk)	66.5±2.4%	27.5±4.6%

Values are means ± SD; n = 5 mice for each group. Micro-CT, micro-computed tomography.
