Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Again seen are fibrotic changes in the right upper lobe , consistent with post-radiation changes . Surgical clips are seen overlying the right breast . There is slight opacification of right heart border by an opacity in the right middle lobe , and the left heart border appears slightly indistinct with opacification of the left lung base . These areas correspond to the recent opacities seen on the PET CT . These are of indeterminate age and may again represent infection or an inflammatory process . Irregular lucency of the right distal clavicle is also a sequels of prior radiation .
    OUTPUT:
    
Grossly similar appearance of right middle lobe and left lower lobe infiltrates , which may be consistent with pneumonia , although comparison with PET - CT is difficult . Clinical correlation is recommended .
