    INPUT: AP semi-upright portable view of the chest is provided . Midline sternotomy wires and mediastinal clips are noted . The patient is intubated with the endotracheal tube tip residing approximately 6 .6 cm above the carina . There are coarsened interstitial markings noted bilaterally concerning for interstitial pulmonary fibrosis . There is a 2 .5 x 3 .3 cm opacity in the right suprahilar region , of unclear etiology . A small right pleural effusion may be present given the blunted right CP angle , though pleural thickening is also within the ddx . Comparison with prior imaging studies would be helpful to assess for any interval changes . The heart size is normal . Mediastinal contour is unremarkable . No acute bony abnormalities .
    OUTPUT:
    
1 . Findings suggestive of interstitial pulmonary fibrosis with small right pleural effusion ( vs pleural thickening ) . Please correlate clinically and comparison with prior imaging studies would be helpful to assess interval change . 2 . 2 .5 x 3 .3 cm opacity in the right suprahilar region - correlate clinically and in the absence of prior imaging , a chest CT is recommended .
