Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: AP and lateral views of the chest were obtained . The heart size is top normal . The mediastinal and hilar contours are stable . There are low lung volumes . There is slight blunting of the bilateral costophrenic angles , which may represent small pleural effusions . Streaky opacities , more at the left lung base than the right , were present on the prior study and likely represent atelectasis but underlying pneumonia can not be excluded . Multiple compression deformities of thoracic spine are again seen , stable compared to the prior study .
    OUTPUT:
    
Slight blunting of both costophrenic angles with stable streaky opacities at the lung bases consistent with atelectasis . Underlying pneumonia can not be excluded .
