Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The patient is rotated somewhat to the left . The cardiac silhouette remains mild to moderately enlarged . There is slight increase in central pulmonary vascular prominence suggesting mild pulmonary vascular congestion . There may be slight prominence of the main pulmonary artery which can be seen with underlying pulmonary hypertension . No pneumothorax is seen . The lungs remain relatively hyperinflated , consistent with COPD . No discrete focal consolidation is seen to suggest lobar pneumonia . There is slight blunting of the costophrenic angles , also present on the prior study , without large pleural effusion seen .
    OUTPUT:
    
Mild pulmonary vascular congestion and mild to moderate cardiomegaly . Persistent blunting of the costophrenic angles without large pleural effusion seen . No discrete focal consolidation to suggest lobar pneumonia .
