Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: A frontal view of the chest was obtained portably . The nasogastric tube follows the expected course , extending below the diaphragm , although the tip is not visualized . Lung volumes are slightly low , resulting in bronchovascular crowding . There is mild bibasilar atelectasis . No focal consolidation , pleural effusion or pneumothorax . Heart size and mediastinal silhouettes are within normal limits allowing for lung volumes . There is mild redistribution of blood flow into the upper pulmonary vasculature , suggesting pulmonary vascular congestion , without overt pulmonary edema .
    OUTPUT:
    
Nasogastric tube extends below the diaphragm , although the tip is not visualized .
