Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The tip of the left PICC projects over the expected location of the right atrium . Recommend proximal repositioning by 4 cm to the level of the cavoatrial junction . The right internal jugular central venous catheter terminates at the low SVC , unchanged from prior . Overall , aeration of the lungs appear improved from multiple recent prior examinations . A confluent opacity within the right lung base persists and may be secondary to asymmetric pulmonary edema or aspiration / infection . There is no large pleural effusion and no pneumothorax . Cardiomediastinal and hilar contours are within normal limits .
    OUTPUT:
    
1 . Left PICC in the right atrium , proximal repositioning by 4 cm is recommended . 2 . Improved lung parenchymal opacities with decreased edema . Persistent consolidation in the right lower lobe may reflect asymmetric edema versus aspiration / infection . Dr . ___ , communicated the PICC position and recommendations to ___ ( IV RN ) at 15 : 29 on ___ by telephone , 2 minutes after discovery .
