Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: When compared to prior , there has been slight interval improvement in the degree of pulmonary edema . Blunting of the lateral costophrenic angles suggests small bilateral effusions , likely decreased from prior . Streaky retrocardiac and right basilar opacities are likely atelectasis . Moderate enlargement of the cardiac silhouette is similar compared to prior . Atherosclerotic calcifications are noted in the aorta . Right chest wall tunneled venous catheter is noted as well surgical clips of the upper mediastinum on the left . No acute osseous abnormalities .
    OUTPUT:
    
Interval improvement in degree of mild pulmonary edema with small persistent bilateral effusions . Enlarged cardiac silhouette which could potentially be due to cardiomegaly although pericardial effusion could also have this appearance .
