Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: In comparison to the most recent prior study , there is improved aeration at the right lung base with improved definition of the right hemidiaphragm and right heart border suggesting decreased atelectasis and pleural fluid . The left lung remains clear without pleural effusion or focal consolidation . No pneumothorax is present . The right hemidiaphragm remains elevated compatible with prior right lung resection . There is decreased but persistent mild pulmonary vascular congestion . The cardiomediastinal silhouette remains prominently enlarged but stable . Surgical clips project to the right of the trachea , compatible with prior lung resection .
    OUTPUT:
    
1 . Improved aeration of the right lung base compatible with decreased atelectasis and pleural fluid . 2 . Improved but persistent mild pulmonary vascular congestion . 3 . Stable appearance status post right partial lung resection .
