Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The lung volumes are low , resulting in vascular crowding . Despite this there is vascular congestion and probable , small bilateral pleural effusions . Retrocardiac opacity is likely due to compressive atelectasis . The heart size is large . No pneumothorax is seen . A nasogastric tube is seen coursing through the esophagus and terminating off the image . Previously noted left rib fracture is not well visualized on the current exam .
    OUTPUT:
    
Moderate pulmonary edema and small bilateral pleural effusions . Probable retrocardiac compressive atelectasis , though infection can not be excluded .
