I'm not sure if your question is about pulmonary edema or pulmonary embolism. I interpreted the question asking about the latter, embolism.
My Radiologist is unavailable at this time, I was just going to ask him! (Is there a Rad. in your area whom you may ask?)
I got this off the web, @ medceu, it's one of their tests. Very informative.
The initial chest x-ray (CXR) findings of a patient with PE are virtually always normal.
On rare occasions they may show the Westermark sign, a dilatation of the pulmonary vessels proximal to an embolism along with collapse of distal vessels, sometimes with a sharp cutoff.
Over time, an initially normal CXR often begins to show atelectasis, which may progress to cause a small pleural effusion and an elevated hemidiaphragm.
After 24-72 hours, one third of patients with proven PE develop focal infiltrates that are indistinguishable from an infectious pneumonia.
A rare late finding of pulmonary infarction is the Hampton hump, a triangular or rounded pleural-based infiltrate with the apex pointed toward the hilum, frequently located adjacent to the diaphragm.
Will try to find more for you.
