Abstract

High resolution X-ray microtomography (micro-CT) was used for the detection of emphysema in live mice. Emphysema was induced in C57BL/6 J mice by intratracheal instillation of different amounts of porcine pancreatic elastase. This emphysema could be clearly detected by micro-CT seven weeks post-treatment: analysis of the whole data set of virtual cross-sections showed the presence of a dose-dependent level of emphysema.
