Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lung volumes are low limiting evaluation . The heart size appears grossly stable allowing for slight differences in technique . There is prominence of the right pulmonary hilum which is of unclear etiology . Mild ground - glass opacity is seen within the lungs which could reflect a component of mild edema . No large effusion or pneumothorax is seen . The mediastinal contour appears unchanged . No bony abnormalities .
    OUTPUT:
    
Prominence of the right pulmonary hilum , possibly due to technique with mild diffuse ground - glass opacity in the lungs suggesting pulmonary edema . Consider dedicated PA and lateral views to better assess .
