FINDINGS:
Underinflation of the lungs makes it difficult to say whether interstitial
 abnormality is present. There is no mediastinal venous engorgement,
 cardiomegaly, or pleural effusion so I doubt that pulmonary edema is present.
 The mediastinal, and hilar contours are normal.

IMPRESSION:
Suggest repeat radiographs it deeper inspiration to determine if the mild
 interstitial pulmonary abnormality is present. This is unlikely to be
 pulmonary edema and its chronicity is indeterminate.
