    INPUT: AP and lateral views of the chest were obtained with patient positioned upright . In comparison with prior chest radiographs and chest CT , there is improvement in scattered opacities seen on prior exam with near - complete resolution . There are coarsened interstitial markings which could represent component of fibrosis . No new consolidation is seen . No effusion or pneumothorax . Patient rotation limits evaluation of the mediastinum . The heart size appears grossly stable and top normal in overall size . The imaged osseous structures appear intact .
    OUTPUT:
    
Interval improvement in previously noted scattered pulmonary opacities . There is a probable component of fibrosis likely accounting for interstitial coarsening .
