Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lung volumes are markedly diminished , however , similar to prior exams . There is mild interstitial prominence on the current study slightly accentuated over prior studies with prominence of bilateral hila . No focal infiltrate is identified . The cardiomediastinal configuration and morphology is stable . There is subtle blunting of the right costophrenic angle , possibly indicating a small effusion . No pneumothorax is evident . Body habitus limits evaluation of the osseous structures , but they are grossly stable .
    OUTPUT:
    
Low lung volumes . There is likely mild interstitial edema which has developed in the interval . A tiny right pleural effusion is also suspected . Given normal heart size , this is suspected non-cardiogenic pulmonary edema .
