Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Endotracheal tube tip terminates approximately 4 cm from the carina . An enteric tube tip courses below the left hemidiaphragm with tip off the inferior borders of the film . Near total opacification of the left hemithorax is new and concerning for left lung atelectasis / collapse . The heart size is difficult to assess given the near complete opacification of the left hemi thorax , though minimal visualization of the right heart border suggests that there may be minimal leftward shift of mediastinal structures . Patchy opacities in the right lung base reflect areas of atelectasis . No large pneumothorax is demonstrated . The extreme right lateral chest is excluded from the field of view . Previously seen right anterior rib fractures are not evident on the current exam . Cervical spinal fusion hardware is incompletely assessed .
    OUTPUT:
    
1 . Endotracheal and enteric tubes in standard positions . 2 . Near complete opacification of the left hemithorax most likely due to left lung atelectasis / collapse . 3 . Right basilar atelectasis . Known right - sided rib fractures are better assessed on the previous CT .
