Figure 2.

Radiographic and computed tomography images of the thorax of a calf from group 1 (acute respiratory disease) with a respiratory score of 7 and body temperature of 40.5 C. Mycoplasma bovis was isolated and a bacterial coinfection was present. (A) Lateral radiograph and (B) sagittal reconstructed computed tomography (CT) image of the thorax in a lung window illustrating the alveolar lung pattern (black arrow) involving both cranial lung lobes, especially the right cranial lung lobe. (C) 3D reconstructed image of the air-filled lung. The cranial and cranioventral aspects of the lungs lack air-filling and are therefore not 3D reconstructed. (D) Transverse image of the thorax at the caudal aspect of the cardiac silhouette demonstrates the various regions in the lung with an alveolar lung pattern.
