Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lung volumes are relatively low . There is somewhat linear right midlung opacity with more hazy opacity projecting over the left midlung . While some of this may be due to atelectasis given low lung volumes , superimposed infection would certainly be possible . The cardiomediastinal silhouette is within normal limits . No acute osseous abnormalities .
    OUTPUT:
    
Focal right midlung opacity with less well - defined hazy left mid to lower lung opacities . While some this may be accounted for by atelectasis , there is suspected superimposed infection .
