Dark-field chest radiograph, conventional x-ray, and CT of human body 8. Median visual grading (encircled numbers) of dark-field chest radiograph (a) by three independent readers shows a markedly reduced dark-field signal in left lung lower zone and to a minor degree in both middle zones, compared to other regions. Median visual grading of transmission in conventional x-ray (b) shows reduced transmission in the right lung, especially in the middle zone, and a markedly reduced transmission in the lower zone of the left lung. Sagittal (c, e) and coronal (d) CT images show interstitial and alveolar infiltrates (red arrows) in depending parts of the right and left upper and lower lobes. Furthermore, there is an enlargement of the heart with a significant haemopericardium (orange arrow) and small left-sided pleural effusion (green arrow). Asterisk marks the location of the endotracheal tube
