Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Frontal and lateral views of the chest were obtained . Relative opacity projecting over the right lung apex at the level of the anterior right first rib likely relates to the first rib . However , AP lordotic views would help in confirmation . The lungs are relatively hyperinflated with flattening of the diaphragms , suggesting chronic obstructive pulmonary disease . There is mid - to - lower lung atelectasis bilaterally . Mild pulmonary vascular congestion is seen . Minimal to mild interstitial edema is again seen . Cardiac and mediastinal silhouettes are stable .
    OUTPUT:
    
1 . Hyperinflated lungs consistent with COPD . Minimal interstitial edema , improved since prior . 2 . Bibasilar atelectasis . 3 . Opacity projecting over the right lung apex at the level of the anterior right first rib may relate to the rib ; however , suggest further evaluation / confirmation on AP lordotic view .
