Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: AP upright and lateral views of the chest are provided . The lungs are clear without focal consolidation , effusion , or pneumothorax . The heart is normal in size . Minimal prominence of the right pulmonary hilum appears essentially stable allowing for slight differences in technique and may be slightly magnified given technique . Atherosclerotic calcification along the aortic knob noted . Bony structures are intact . Arthropathy of the right AC joint is noted .
    OUTPUT:
    
No acute intrathoracic process . Mild prominence of the right pulmonary hilum is likely attributable to technical factors , though consider a dedicated PA and lateral view to more fully assess .
