Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The lung volumes are low . The superior segment of the right lower lobe is collapsed . The left lower lobe is completely opacified which may likely represent atelectatic collapse and less likely a consolidation . The mild pulmonary vascular congestion is unchanged . Moderate to severe cardiomegaly is stable . The mediastinal and hilar contours are stable . Small bilateral pleural effusions are unchanged . The right PICC line terminates in the mid SVC . 2 NG tubes terminate in the mid stomach . The ET tube is approximately 6 cm from the carina .
    OUTPUT:
    
ET tube is in appropriate position . The NG tubes are in appropriate positions . A retrocardiac opacity may represent left lower lobe atelectasis and less likely a pneumonia .
