Dark-field chest radiograph, conventional x-ray, and CT of human body 6. Median visual grading (encircled numbers) of x-ray dark-field chest radiograph (a) by three independent readers shows markedly reduced dark-field signal in middle and lower zones of the right lung. Median visual grading of transmission in conventional x-ray (b) shows reduced transmission in the right lung upper zone as well as right and left lung middle zones and is lowest in right-lung lower zone. Sagittal (c, e) and coronal (d) CT images show interstitial and alveolar infiltrates in the right upper lobe, left upper lobe, and right middle lobe, as well as extensive pulmonary consolidation (red arrows) in the right lower lobe and, to a lesser extent, in left lower lobe. Asterisk marks the location of the endotracheal tube
