Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lung volumes are low . Heart size is moderately enlarged . Mediastinal contours remain relatively unchanged with persistent bulging of the right mediastinal contour possibly reflective of a continued right paraesophageal collection which was better appreciated on the recent CT scan . Hilar contours are normal and there is no pulmonary edema . Streaky opacities within the lower lobes bilaterally likely reflect areas of atelectasis which appear improved compared to the prior study . There has also been near complete resolution of the previously noted bilateral pleural effusions . No pneumothorax is identified . No subdiaphragmatic free air is demonstrated . Clips at the gastroesophageal junction indicate prior Nissen fundoplication .
    OUTPUT:
    
1 . Improved aeration of the lung bases with residual bibasilar atelectasis and near complete resolution of the previously noted bilateral pleural effusions . 2 . Persistent right mediastinal contour bulge which likely reflects the right paraesophageal collection , better assessed on previous CT . 3 . No subdiaphragmatic free air .
