    INPUT: The inspiratory lung volumes are decreased from the most recent prior study and considerably lower on the lateral radiographs .

Bibasilar atelectasis is greater on the left compared to the prior . No significant pleural effusion or pneumothorax is detected . The pulmonary vasculature is not engorged . The cardiac silhouette is top normal in size . The mediastinal contours remain prominent partially due to unfolding of the thoracic aorta . Calcification of the aortic knob is unchanged .

Surgical clips projecting over the right upper quadrant of the abdomen are compatible with prior cholecystectomy .
    OUTPUT:
    
1 . No focal consolidation concerning for pneumonia . 2 . Decreased lung volumes with bibasilar atelectasis greater on the left .
