Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lung volumes are low , which limits assessment . The stomach is distended . The right hemidiaphragm is elevated . There is hazy bilateral vasculature , but it is unclear how much of this is due to poor inspiration . Patchy areas of volume loss are seen bilaterally . The right hilum is prominent , but it is unclear how much of this is due to low volumes .
    OUTPUT:
    
Low lung volumes limit assessment . Pulmonary edema and infection are both possibilities . Recommend followup to reassess the hilum when the patient is in more stable pulmonary status .
