Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: In comparison to prior exam , there is improved inspiratory effort and improved lung volumes . Allowing for changes due to this , the cardiomediastinal silhouettes are stable , possibly with mild cardiomegaly . A right - sided PICC line terminates at the mid to low SVC . The bilateral hila are unremarkable . Retrocardiac opacity likely represents basilar atelectasis . The lungs are otherwise clear . There is no evidence of pulmonary vascular congestion . There is a persistent small right pleural effusion . There is no left pleural effusion or pneumothorax .
    OUTPUT:
    
1 . Low lung volumes . Persistent small right pleural effusion with basilar atelectasis . No focal lung consolidation . 2 . Right PICC line terminating in the mid to low SVC .
