    INPUT: Tracheostomy tube tip is in unchanged position . Lung volumes remain low . Heart size is mildly enlarged but unchanged . Mediastinal contour is similar . Diffuse increased interstitial and ground - glass opacities are seen bilaterally , compatible with chronic interstitial lung disease with possible superimposed mild pulmonary edema . No pleural effusion or pneumothorax is present . Percutaneous gastrojejunostomy catheter is noted with the distal aspect not completely imaged on this film .
    OUTPUT:
    
Similar appearance of diffuse increased interstitial ground - glass opacities bilaterally , likely reflecting a combination of chronic interstitial lung disease with superimposed mild pulmonary edema .
