    INPUT: In comparison to ___ study there is diffuse pulmonary opacities seen , with progression in the right upper and right middle lobes as well as new opacities in upper lung . Again given the setting setting of hemoptysis pulmonary hemorrhage can not be excluded as well as pulmonary edema and aspiration . Given the rapidity of the progression pneumonia is less likely . Again seen is a right jugular central venous catheter which terminates in the right atrium . The cardiomediastinal silhouette appears stable when compared to previous studies .
    OUTPUT:
    
Progression of diffuse pulmonary opacities in the right upper , right middle , and left upper lobes that may represent pulmonary hemorrhage in the setting of hemoptysis versus pulmonary edema versus aspiration , with pneumonia being less likely given rapid time course .
