X-ray chest radiography is an inexpensive and broadly available tool for initial assessment of the
lung in clinical routine, but typically lacks diagnostic sensitivity for detection of pulmonary diseases
in their early stages. Recent X-ray dark-field (XDF) imaging studies on mice have shown significant
improvements in imaging-based lung diagnostics. Especially in the case of early diagnosis of chronic
obstructive pulmonary disease (COPD), XDF imaging clearly outperforms conventional radiography.
However, a translation of this technique towards the investigation of larger mammals and finally
humans has not yet been achieved. In this letter, we present the first in-vivo XDF full-field chest
radiographs (32 × 35 cm²) of a living pig, acquired with clinically compatible parameters (40s scan time,
approx. 80 μSv dose). For imaging, we developed a novel high-energy XDF system that overcomes the
limitations of currently established setups. Our XDF radiographs yield sufficiently high image quality
to enable radiographic evaluation of the lungs. We consider this a milestone in the bench-to-bedside
translation of XDF imaging and expect XDF imaging to become an invaluable tool in clinical practice,
