Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Endotracheal tube tip terminates approximately 3 cm from the carina . Orogastric tube tip courses below the diaphragm , and loops within the region of the stomach , with the tip not assessed . Low lung volumes are present with elevation right hemidiaphragm , of unknown chronicity . Heart size is mildly enlarged . The mediastinal contours are unremarkable . There is mild pulmonary vascular engorgement . Bibasilar airspace opacities are more pronounced in the right lung base , and likely reflect atelectasis though infection can not be completely excluded . No large pleural effusion or pneumothorax is demonstrated . A VP shunt catheter is noted coursing along the right aspect of the neck , chest and upper abdomen . Extensive degenerative changes are noted in the left shoulder .
    OUTPUT:
    
1 . Endotracheal and orogastric tubes appear to be in standard positions . 2 . Low lung volumes with elevation of the right hemidiaphragm . Bibasilar airspace opacities likely reflect atelectasis though infection can not be excluded . 3 . Mild pulmonary vascular congestion .
