FINDINGS:
There are diffuse bilateral interstitial markings, overall unchanged since
 . This is consistent with chronic lung disease. No new areas of
 focal consolidation or pleural effusions. No pneumothorax.  Heart size is top
 normal, stable from prior.  Atherosclerotic calcifications are seen in the
 coronary arteries, better appreciated on the lateral view.

IMPRESSION:
1. No acute intrathoracic process. Stable bilateral interstitial markings,
 likely chronic lung disease.
 2. Coronary artery calcifications.
