    INPUT: In comparison to the prior radiograph , there is now increased partial collapse of the right middle lobe and worsening atelectasis / collapse of the right lower lobe . Hazy opacity in the right middle lung zone and prominence of the fissures suggest increased pleural fluid ; however , it is difficult to quantify due to the atelectasis . Cardiomediastinal silhouette is difficult to evaluate also due to atelectasis . The left lung is clear . There is no pneumothorax or acute skeletal abnormalities .
    OUTPUT:
    
Increased partial collapse of right middle lobe and worsening atelectasis / collapse of the right lower lobe . Likely increased right pleural effusion ; however , difficult to quantify due to the atelectasis .
