Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lung volumes are lower compared to the previous study . This accounts for the increased size of the cardiac silhouette which appears moderately enlarged . Mediastinal and hilar contours are grossly unchanged . Crowding of bronchovascular structures is present , without overt pulmonary edema . Patchy opacities in the lung bases may reflect atelectasis . No large pleural effusion or pneumothorax is detected , however the extreme left costophrenic angle is excluded from the field of view . Multiple clips are seen in the right upper quadrant of the abdomen .
    OUTPUT:
    
Lower lung volumes compared to the previous radiograph with patchy atelectasis in both lung bases .
