Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The lung volumes are low . There are patchy new opacities in the lower lungs . Most often these could be attributed to atelectasis in the setting of low lung volumes , but not entirely specific . In addition , the pulmonary vasculature appears indistinct and prominent suggesting fluid overload . A curvilinear line projecting over the right upper hemithorax mimics pneumothorax , although the clear presence of lung markings beyond the edge of the shadow and the lack of medial delineation of the shadow make an artifact more likely than a real pneumothorax . There is no definite pleural effusion . The gastric bubble projects over the left upper quadrant , but there is no definite free air .
    OUTPUT:
    
1 . Curvilinear interface projecting over the right upper lung , which mimics a pneumothorax , although it is probably an artifact . Repeat chest radiography is suggested to confirm . 2 . Findings suggesting mild - to - moderate pulmonary vascular congestion . 3 . Patchy lower lobe opacities , most suggestive of atelectasis in the setting of quite low lung volumes , although other etiologies such as pneumonia or aspiration are not excluded by this study . 4 . No evidence for free intraperitoneal air .
