Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There are low inspiratory volumes , significantly lower than on the most recent prior chest radiograph . Allowing for this , the cardiomediastinal silhouette is probably similar in size . The left - sided pacemaker type device and right IJ lines are similar in configuration . Right - sided pleural drain is again noted , also similar in configuration . The previously seen right effusion is smaller . Curvilinear lucency at the right lung base raises the question of a small pneumothorax at the right lung base versus ___ artifact . Some confluent opacity at the right lung base is compatible with residual collapse and / ___ consolidation . The area of opacity questioned along the upper right chest wall on the most recent prior film is no longer visualized , likely represent artifact . As before , the left lung base is obscured obscured by the generator device . There is probably some subsegmental atelectasis at the right base , slightly more pronounced on the prior study . Mild vascular plethora is present , likely accentuated by low inspiratory volumes .
    OUTPUT:
    
Considerable improvement in right pleural effusion . New linear lucency at the right lung base could reflect either a small pneumothorax ___ ___ artifact . Residual collapse and / ___ pneumonic consolidation at the right base is present . Low inspiratory volumes . Atelectasis at the left base probably slightly increased . Mild vascular plethora , likely accentuated by low lung volumes .
