Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Endotracheal tube tip terminates approximately 3 .8 cm from the carina . An orogastric tube tip is noted within the distal stomach . Lung volumes are low . Heart size is normal . Mediastinal contours are unremarkable . Crowding of the bronchovascular structures is noted , and mild pulmonary vascular congestion is likely present . Additionally , more focal somewhat linear opacities within both upper lobes appear to be associated with fibrotic changes . No pleural effusion or pneumothorax is identified , although the right costophrenic angle is excluded from the field of view . Diffuse gaseous distention of the bowel loops are noted within the upper abdomen . No acute osseous abnormality seen . Surgical anchors are noted projecting over the right shoulder .
    OUTPUT:
    
1 . Standard positions of the endotracheal and orogastric tubes . 2 . Focal , somewhat linear opacities within both upper lobes which may be due to a chronic interstitial process . Correlation with prior imaging is recommended . Aspiration or infection , however , can not be completely excluded . 3 . Mild pulmonary vascular congestion in the setting of low lung volumes .
