Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: NG tube in situ coursing out of sight inferiorly . Mild interval increase in transverse cardiac diameter . Mild cephalization of pulmonary blood vessels . Mild airspace opacification seen in the lower lung zones most likely represent atelectasis , but may represent aspiration or new developing pneumonia . No large associated effusion . No pneumothorax .
    OUTPUT:
    
Interval increase in cardiac diameter with mild pulmonary venous congestion suggest fluid overload or cardiac decompensation . Mild new airspace opacification seen in the lung bases which most likely represents atelectasis , but aspiration and early infection can not be excluded . Short - term interval follow - up imaging advised .
