<qa>  What is the term for infiltrates considered consistent with pulmonary4. Infiltrates considered consistent with pulmonary edema include any infiltrates not fully explained by mass, atelectasis, or effusion or opacities known to be chronic greater than 1 week. Vascular redistribution, indistinct vessels, and indistinct heart borders alone are not considered consistent with pulmonary edema and thus would not count as qualifying opacities for this study.
