Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The cardiac , mediastinal and hilar contours appear unchanged , allowing for small differences in technique . There are patchy new basilar opacities with hazy density in the right costophrenic sulcus and more streaky left basilar opacities . These are more typical of atelectasis than pneumonia . There is no evidence for congestive heart failure .
    OUTPUT:
    
Streaky and vague basilar opacities , more suggestive of atelectasis than pneumonia , but if pneumonia is a continuing potential clinical concern then short - term followup radiographs could be considered .
