Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Increased interstitial markings are seen throughout the lungs which are chronic likely due to underlying interstitial process . Lower lung volumes seen on the current exam and subsequent retrocardiac opacity is likely due to atelectasis . There is no effusion or overt edema . Right apical scarring is again noted . This may also cause increased opacity at the right paratracheal stripe region however underlying lesions such as adenopathy is difficult to exclude .
    OUTPUT:
    
Chronic changes in the lungs without definite focal consolidation . Increased soft tissue in the region of the right paratracheal stripe , potentially related to adjacent right apical scarring and AP technique , however underlying adenopathy is possible . Suggest repeat exam with PA technique if patient is amenable or alternatively CT scan for re-evaluation .
