Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Heart size is top normal . The mediastinal and hilar contours are unremarkable . Pulmonary vasculature is not engorged . No focal consolidation , pleural effusion or pneumothorax is present . Streaky opacities are noted in the lung bases which may reflect areas of atelectasis . Lungs are hyperinflated . Previously noted right middle lobe nodule seen on CT is not well assessed on the current radiograph . There are mild multilevel degenerative changes seen in the thoracic spine .
    OUTPUT:
    
1 . Streaky bibasilar atelectasis without focal consolidation . 2 . Known right middle lobe nodule seen on prior CT is not well assessed on the current radiograph . As was recommended at the time of the previous CT , followup chest CT should have performed within 3 months , and correlation with any previous imaging is recommended . If this follow up chest CT has not occurred , then a non-emergent follow up chest CT is recommended to be done at this time .
