Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Endotracheal tube tip is within the proximal right mainstem bronchus . An enteric tube is cold within the esophagus with distal aspect terminating in the distal esophagus . Low lung volumes are present . This accentuates the size of the cardiac silhouette which appears mildly enlarged . Widening of the superior mediastinal contour may be due to low lung volumes and supine positioning . Crowding of bronchovascular structures is present with possible mild pulmonary vascular congestion but no overt pulmonary edema . Atelectasis is noted in the lung bases . No pleural effusion or pneumothorax is identified on this supine exam . There are no acute osseous abnormalities .
    OUTPUT:
    
1 . Right mainstem bronchial intubation . 2 . Coiled enteric tube within the esophagus , with tip in the distal esophagus . 3 . Low lung volumes with bibasilar atelectasis and possible mild pulmonary vascular congestion .
