Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The cardiac , mediastinal and hilar contours appear stable . Surgical clips are present along the mediastinum and base the left neck . There is no pleural effusion or pneumothorax . Medial right basilar opacity has partly resolved . A known large medial right basilar lung nodule is partly obscured . Patchy scarring and right lower lateral pleural thickening appear unchanged to somewhat decreased . Right suprahilar nodule persists but is difficult to assess for small changes with respect to the prior images . Pulmonary nodules were better delineated on recent CT imaging .
    OUTPUT:
    
No evidence of acute cardiopulmonary disease . Poor visualization of known pulmonary nodules ; short - term follow - up CT imaging may be helpful to reassess known nodules if needed clinically .
