    INPUT: Overall , the appearances are similar to the prior study . The opacities in the right lung are slightly improved . The previously seen question temperature probe is no longer visualized . Otherwise , lines and tubes and parenchymal findings are similar to the prior study . As before , the left hemidiaphragm and left costophrenic sulcus are excluded from the film . Incidental note is made of well corticated tapering of both collapse distal clavicles , question postsurgical .
    OUTPUT:
    
Very slight interval improvement in right lung opacities . Otherwise , I doubt significant interval change .
