Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: A portable semi-erect frontal chest radiograph was obtained . The patient is rotated , limiting evaluation of the cardiomediastinal silhouette . Mild to moderate pulmonary edema and small bilateral pleural effusions are likely unchanged , perhaps slightly worse on the left . No definite new focal consolidation is identified , although the right lower lobe opacity previously noted would be obscured by the patient 's current positioning . The visualized upper abdomen is remarkable for a stent projecting over the right upper quadrant , unchanged compared to prior exam .
    OUTPUT:
    
1 . Persistent mild pulmonary edema and bilateral small pleural effusions are similar to slightly increased on the left . 2 . No definite new focal consolidation , although patient rotation makes evaluation , including of the previously noted right lower lobe opacity , difficult .
