Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Moderate cardiomegaly is re- demonstrated , perhaps minimally increased from the previous study . Widening of the right paratracheal stripe is attributable to tortuous vessels , better assessed on the previous CT . Enlargement of the pulmonary artery is again noted suggestive of underlying pulmonary arterial hypertension . Lungs remain hyperinflated . There is mild pulmonary edema , new in the interval . Patchy bibasilar airspace opacities likely reflect areas of atelectasis . No large pleural effusion or pneumothorax is appreciated . There are no acute osseous abnormalities .
    OUTPUT:
    
Mild pulmonary edema and bibasilar atelectasis .
