Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lung volumes remain low . Bilateral pleural effusions on the prior exam appear to have essentially resolved . Mild indistinctness of the left costophrenic angle could suggest some residual small effusion . Left lower lung atelectasis has markedly improved . Mild cardiomegaly , even in the presence of low lung volumes and this AP view is likely still present . Aortic knob calcifications are unchanged . No focal consolidation to suggest a focal pneumonia . No pneumothorax . No edema . The descending thoracic aorta slightly tortuous , unchanged . Dextroconvex scoliosis of the thoracic spine is moderate , unchanged . Surgical clips projecting over the right upper abdomen are consistent with cholecystectomy .
    OUTPUT:
    
No focal pneumonia . Persistent low lung volumes with interval near complete resolution of pleural effusions .
