Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Endotracheal tube terminates approximately 6 .9 cm from the carina . Nasogastric tube tip courses below the diaphragm , off the inferior border of the film . Heart size is borderline enlarged . Mediastinal contours are within normal limits . The hila are unremarkable . There is no pulmonary vascular congestion . Streaky bibasilar airspace opacities , more pronounced on the left , likely reflect atelectasis though aspiration is not excluded . No large pleural effusion or pneumothorax is detected on this supine study . No grossly displaced fractures are visualized .
    OUTPUT:
    
1 . Endotracheal and nasogastric tubes in standard positions . 2 . Bibasilar airspace opacities likely reflecting atelectasis though aspiration can not be excluded .
