Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Somewhat limited evaluation due to patient rotation . The lungs are moderately well inflated . No definite change since outside study performed ___ hours prior . Again seen is moderate to moderately severe cardiomegaly , though mediastinal and hilar contours are not effectively assessed due to considerable the patient rotation . Also again seen is apparent moderate pulmonary edema with probable small bilateral , left greater than right , pleural effusions . Left lower lobe collapse and / or consolidation is again seen . Heterogeneous radiopaque material projecting over the central mid hemi thorax is again noted . Targeted review of an outside CT from ___ suggests this lies within the spine and likely represents residua from prior kyphoplasty / vertebroplasty .
    OUTPUT:
    
1 . Persistent moderate pulmonary edema with small bilateral , left greater than right , pleural effusions and severe cardiomegaly . 2 . Left lower lobe opacity likely represents combination of pleural fluid , atelectasis , and asymmetric pulmonary edema however superimposed infection can not be excluded . Clinical correlation is requested . 3 . Heterogeneous radiopaque material projecting over central mid hemi thorax is consistent with prior kyphoplasty / vertebroplasty .
