    INPUT: Right PICC tip terminates in the low SVC . The heart size appears moderately enlarged . The mediastinal contours unremarkable . Low lung volumes resulting crowding of bronchovascular structures without overt pulmonary edema . Patchy opacities are seen in the lung bases which may reflect areas of atelectasis , but aspiration or infection can not be excluded . Small bilateral pleural effusions are likely present . No pneumothorax is demonstrated . There are no acute osseous abnormalities .
    OUTPUT:
    
Bibasilar patchy airspace opacities may reflect atelectasis , but aspiration or infection can not be excluded . Probable trace bilateral pleural effusions .
