Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: AP upright and lateral views of the chest were provided . Evaluation is quite limited given the low lung volumes . There is mild pulmonary edema evidenced by diffuse ground - glass pulmonary opacities . There is no large effusion or pneumothorax . Cardiomediastinal silhouette appears grossly stable though low lung volumes significantly limit evaluation . Imaged osseous structures appear intact .
    OUTPUT:
    
Diffuse ground - glass pulmonary opacities most likely reflecting pulmonary edema . Recommend post - diuresis films to exclude underlying pneumonia .
