Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Portable AP upright chest radiograph shows stable to slight slight decrease in the cardiac size and no central pulmonary vascular congestion compared to the most recent previous studies . Haziness in the right costophrenic angle laterally is slightly decreased and may represent some chronic pleural fluid versus pleural diaphragmatic adhesions . Note is made of a sharper curve to the patient 's Port - A - Cath tubing where it extends from the expected region of the left innominate vein into the superior vena cava . A lateral view with follow may be helpful tissue to assure this is in unchanged position .
    OUTPUT:
    
1 . No plain film findings of CHF . Note chronic blunting of right CP angle . 2 . Note less broad curvature of Port - A - Cath tubing as it enters SVC . Recommend lateral view when the patient has followup to assure port tubing is in unchanged position and not within a mediastinal vein . This may also clarify right CP angle findings
