Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lordotic positioning . Slightly low inspiratory volumes . The heart is not enlarged . Aorta is slightly unfolded . There is mild patchy opacity at the left base , which could represent atelectasis or early changes due to aspiration . Otherwise , no focal infiltrate identified . No CHF , effusion , or pneumothorax detected . Mild irregularity of the right second rib laterally is noted , but could represent an old injury . Otherwise , visualized ribs are grossly unremarkable . Note is made of nonvisualization of the supraclavicular companion shadow as well as soft tissue opacity in the adjoining fat .
    OUTPUT:
    
Small patchy opacity at the left lung base , question atelectasis or focus of aspiration . Mild irregularity of the right second rib laterally . Unless there is focal tenderness in this area , this likely represents an old , healed fracture . Otherwise , no acute pulmonary process identified . Mild unfolding of the aorta noted . Opacity in the left supraclavicular fat and effacement of the left clavicular companion shadow . Correlation with physical exam to exclude supraclavicular lymphadenopathy or other soft tissue mass can not location is requested . Please note that this examination is not adequate for evaluation of the cervical or thoracic spine . In addition , correlation with specific sites of chest wall tenderness may also be helpful for assessment .
