Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: A right - sided port is visualized with the catheter tip at the level of the right ventricle . Again noted is blunting of the left costophrenic angle suggestive of a small pleural effusion or pleural thickening , stable in comparison to prior study . Subtle linear opacities in left mid lung are again noted and likely representative of scarring . The lungs are otherwise clear with no evidence of focal consolidation , right - sided effusion or pneumothorax . Cardiomediastinal silhouette is unremarkable . Pleural calcifications are again noted , suggestive of prior asbestos exposure .
    OUTPUT:
    
1 . No acute cardiopulmonary process . 2 . Persistent blunting of the left costophrenic angle suggestive of pleural thickening versus a small pleural effusion . 3 . Evidence of prior asbestos exposure . 4 . Right - sided port with the catheter tip likely in right ventricle .
