Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Rotated positioning . Compared to the prior film , there may have been slight interval improvement in the CHF findings . Otherwise , I doubt significant interval change . Again seen is a left IJ central line with tip over mid SVC an extensive perihilar and parenchymal opacities , including more confluent opacity at the lateral left lung . There may have been subtle improvement in the lateral left chest opacity , but this may also be accentuated by differences in positioning . Minimal blunting of left costophrenic angle is also unchanged . The current film includes the proximal portion of the right humeral diaphysis and shows some increased density there .
    OUTPUT:
    
1 . Slight interval improvement in CHF findings . 2 . Parenchymal opacities , including opacity along the left chest laterally , otherwise essentially unchanged compared with earlier the same day . 3 . Possible deformity of the right humeral diaphysis . Is there history of prior fracture ?
