    INPUT: Tracheostomy tube tip is in standard position . Lung volumes remain low . Heart size is normal . The mediastinal and hilar contours are unchanged . Diffuse course interstitial opacities are re - demonstrated bilaterally compatible with a chronic interstitial lung disease . There may be mild superimposed pulmonary edema , though this is not as pronounced as on the previous examination . No new focal consolidation , pleural effusion or pneumothorax is identified . Percutaneous gastrojejunostomy catheter is incompletely imaged .
    OUTPUT:
    
Diffuse interstitial opacities likely reflective of the patient 's known chronic fibrotic lung disease . There may be superimposed mild pulmonary edema , though this is improved compared to the previous study . No new focal consolidation .
