    INPUT: A tracheostomy tube is present with the tip in the proximal trachea approximately 8 .5 cm from the carina . A right PICC is present with the tip in the mid SVC . Diffuse interstitial abnormalities are consistent with mild pulmonary edema . A more focal opacity at the right base is of uncertain etiology . There is likely a small right pleural effusion . No left pleural effusion is identified . The mediastinal contours are normal . The heart is moderately enlarged .
    OUTPUT:
    
1 . Satisfactory position of the tracheostomy tube and PICC , with the tip in the mid SVC . 2 . Mild pulmonary edema . 3 . Right basilar opacity , which may represent atelectasis or asymmetric edema . A superimposed infection can not be completely excluded . Recommend a repeat radiograph after diuresis . 4 . Small right pleural effusion .
