FINDINGS:
The lungs appear slightly better aerated than the most recent prior
 study.  There is no focal consolidation or pneumothorax.  Again seen is hazy
 opacity in the left retrocardiac and basilar region, likely atelectasis as
 well as a small pleural effusion.  Cardiomediastinal silhouette is unchanged.

IMPRESSION:
1.  Improved aeration in the lungs.
 2.  Left basilar atelectasis and small pleural effusion.
