Dark-field chest radiography allows for assessment of lung alveolar structure by exploiting wave optical properties of x-rays. Here we present first results on the qualitative and quantitative characteristics of dark-field chest radiography in participants with COVID-19 pneumonia. Dark-field radiography shows high accuracy for the detection of COVID-19 and significantly improves diagnostic performance compared to conventional radiography.
In addition, we discuss how spectral information, e.g. from photon-counting detectors, could further improve these clinical darkfield results in the future.
