This atlas of chest imaging is a collection of interesting chest radiographs and computed tomograms (CTs) of the chest. The readings of the films are meant to be illustrative of specific, major findings. The associated text is not intended as a comprehensive assessment of the images.


FIGURE 308e-1

Normal chest radiograph—review of anatomy. 1. Trachea. 2. Carina. 3. Right atrium. 4. Right hemidiaphragm. 5. Aortic knob. 6. Left hilum. 7. Left ventricle. 8. Left hemidiaphragm (with stomach bubble). 9. Retrosternal clear space. 10. Right ventricle. 11. Left hemidiaphragm (with stomach bubble). 12. Left upper lobe bronchus.

FIGURE 308e-2

Normal chest tomogram—note anatomy. 1. Superior vena cava. 2. Trachea. 3. Aortic arch. 4. Ascending aorta. 5. Right mainstem bronchus. 6. Descending aorta. 7. Left mainstem bronchus. 8. Main pulmonary artery. 9. Heart. 10. Esophagus. 11. Pericardium. 12. Descending aorta.


FIGURE 308e-3

CT scan demonstrating left upper lobe collapse. The patient was found to have an endobronchial lesion (not visible on the CT scan) resulting in this finding. The superior vena cava (black arrow) is partially opacified by intravenous contrast.

FIGURE 308e-4

CT scan revealing chronic left lower lobe collapse. Note dramatic volume loss with minimal aeration. There is subtle mediastinal shift to the left.

FIGURE 308e-5

Left upper lobe scarring with hilar retraction with less prominent scarring in right upper lobe as well. Findings consistent with previous tuberculosis infection in an immigrant from Ecuador.

FIGURE 308e-6

Apical scarring, traction bronchiectasis (red arrow), and decreased lung volume consistent with previous tuberculosis infection. Findings most significant in left lung.

FIGURE 308e-7

Chest radiograph demonstrating right upper lobe collapse (yellow arrow). Note the volume loss as demonstrated by the elevated right hemidiaphragm as well as mediastinal shift to the right. Also apparent on the film are an endotracheal tube (red arrow) and a central venous catheter (black arrow).

FIGURE 308e-8

Opacity in the right upper lobe. Note the volume loss as indicated by the elevation of the right hemidiaphragm, elevation of minor fissure (yellow arrow), and deviation of the trachea to the right (blue arrow).
