2. The chest radiograph shows an asymmetric linear, interstitial pattern

The frontal chest radiograph shows a prominent linear pattern throughout the right lung, associated with a small-to-moderate right pleural effusion. No linear or reticular opacities are seen in the left lung. Consolidation is present in the right lower lobe, but the consolidation is not multifocal in distribution. The widening of the superior mediastinum is vascular in nature; no mediastinal mass is present. The opacities present in the right lung are linear in morphology; a nodular pattern is not evident.

Which of the following represents the next, most appropriate step for the assessment of the findings at chest radiography? (Click on the correct answer to proceed to the next panel)

1. Obtaining prior thoracic imaging studies for comparison to determine if the lung findings are new or stable over time
2. Enhanced thoracic CT
3. 1 or 2
4. Thoracic MRI
5. Bilateral, frontal shallow (5°) oblique images to distinguish true lung infiltration from artifact or a chest wall lesion
