Correct!
1. The chest radiograph shows asymmetric reticulation and interlobular septal thickening
The frontal chest radiograph shows unilateral (right-sided) linear and reticular opacities, associated with decreased volume affecting the right thorax. There is no reticulation, septal thickening, or volume loss on the left side. No nodules, cavitary or otherwise, are present. There is no evidence of consolidation. The right lung volume is diminished, whereas the left lung volume is normal; the lung volumes are not abnormally large. No clear pleural effusion is present, although some thickening of the right-sided fissures, versus subpleural edema, is present.
