Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Endotracheal tube tip terminates approximately 3 .4 cm from the carina . The cardiac silhouette size remains mildly enlarged . Mediastinal and hilar contours are relatively unchanged . Widening of the right paratracheal stripe is due to the presence of mediastinal fat deposition . Lung volumes are low . Patchy bibasilar airspace opacities are noted . There is no pulmonary vascular engorgement . Blunting of the costophrenic angles bilaterally likely reflects extrapleural fat deposition as noted on the prior CT . No pneumothorax is identified . There are no acute osseous abnormalities detected .
    OUTPUT:
    
1 . Endotracheal tube in standard position . 2 . Low lung volumes . Bibasilar airspace opacities are nonspecific but could reflect atelectasis , but aspiration or infection are not excluded .
