Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There is again seen a right - sided PICC line whose most medial aspect projects over the superior border of the right clavicle , with tip not well visualized . It is recommended to repeat chest x-ray to confirm tip location . There is a poor inspiratory effort and low lung volumes . Median sternotomy wires are again visualized . Allowing for changes due to rotation and positioning , there is no appreciable interval change in the mediastinal silhouette . The cardiac silhouette is unable to be evaluated secondary to patient positioning . There is interval increase in opacification of bilateral lower lung zones , which is likely due to poor patient positioning , as well as low lung volumes / poor inspiratory effort . This also limits evaluation of interval changes in previously visualized bibasilar atelectasis . There is no evidence of pneumothorax .
    OUTPUT:
    
New right - sided PICC line with distal tip not well visualized . Recommend repeat imaging for clarification of tip location . Otherwise , poor patient positioning and low lung volumes significantly limits this study .
