Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: 2 frontal AP views of the chest were obtained . Overlying trauma board slightly limits evaluation . The endotracheal tube tip position changes in location between the 2 views and terminates approximately 4 .3 to a 8 .2 cm from the carina . Nasogastric tube tip courses below the diaphragm , off the inferior borders on the film . Heart size is likely top normal . The aorta is markedly tortuous and diffusely calcified . The hilar contours are unremarkable . Focal ill - defined opacity within the left mid lung field is concerning for an area of infection . Nodular opacity measuring 12 mm projecting over left lung base is likely a nipple shadow . Streaky right basilar and left upper lobe opacities may reflect infection or atelectasis . No definite pneumothorax is identified , nor is there a large pleural effusion . No acute osseous abnormalities are present .
    OUTPUT:
    
1 . Endotracheal tube tip terminates between 4 and 8 cm from the carina . Nasogastric tube tip is in standard position . 2 . Ill - defined focal opacity in the left mid lung field which is concerning for infectious process . Right basilar and left upper lobe streaky opacities could also reflect atelectasis or infection .
