Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There are low inspiratory volumes , similar prior . A tracheostomy is in place . A left - sided PICC line tip overlies the mid / distal SVC . No pneumothorax is detected . The cardiomediastinal silhouette is similar to the prior film , likely accentuated due to low lung volumes . There is upper zone redistribution and hazy opacity in the right mid and cardiophrenic zones could represent atelectasis . There is minimal subsegmental atelectasis at the left base . No definite effusion . Slight elevation of the right hemidiaphragm with respect to left .
    OUTPUT:
    
Patchy opacity in the right cardiophrenic region likely represents atelectasis , in the setting of low lung volumes . An early pneumonic infiltrate can not be entirely excluded . There is also minimal atelectasis the left lung base . No definite consolidation or gross effusion .
