Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Chest films obtained supine , due to limited patient mobility . Allowing for this , the heart size is borderline enlarged . Prominence of upper zone vessels likely relates to supine technique . Right paratracheal opacity likely represents confluence of vascular and osseous shadows -- however . attention to this area on followup upright film would be recommended to confirm this . No CHF , focal infiltrate , or effusion is identified . No supine film evidence of pneumothorax is seen . Two small rounded densities at the left lung base , one lateral in the midzone and one at the left lung base , appear to represent confluence of vascular and osseous shadows .
    OUTPUT:
    
Doubt acute pulmonary process . Please see comment .
