Figure 1

Contrary to conventional x-ray transmission (A) that reveals only hardly appreciable differences, dark-field (B) radiograms yield a clear discrimination in terms of signal intensity between the lungs from animals in the room air (RA) group as compared to neonatal mice undergoing MV-O2 for 8 h. (C) The corresponding histological sections. Scale bars for radiographies correspond to 5 mm and for histology to 100 μm.
