    INPUT: In comparison to the remote prior study of ___ , there is new opacification of the right lung base silhouetting the right hemidiaphragm and right heart border without significant associated volume loss suggesting a moderate right pleural effusion . Underlying atelectasis , consolidation or infarction is difficult to assess . A right lateral decubitus radiograph is recommended for further evaluation . Blunting of the left costophrenic angle is compatible with a small left pleural effusion . Streaky opacification of the left lung base likely reflects atelectasis . The cardiac silhouette is incompletely evaluated . The mediastinal and hilar contours are within normal limits . Surgical clips in the right upper quadrant are compatible with cholecystectomy . A prominent air-filled loop of bowel in the upper abdomen likely represents large bowel , similar in appearance to ___ .
    OUTPUT:
    
New moderate right pleural effusion . Underlying atelectasis , consolidation or infarction is difficult to assess . A right lateral decubitus radiograph could be considered for further evaluation barring clinical concern for pulmonary embolism , in which case urgent CTA of the chest is recommended .
