Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The patient is rotated to the right significantly limiting evaluation of the mediastinal structures . Allowing for these limitations a faint small focal opacity in the left upper lobe is not appreciably changed since ___ and may correspond to scarring . Bibasilar hazy opacities are likely due to atelectasis , however small pleural effusions can not be excluded on this limited frontal radiograph , and there is mild blunting of the lateral costophrenic sulci . The mediastinal structures are not well evaluated , however , the heart appears mildly enlarged . There is no evidence of pulmonary edema or pneumothorax .
    OUTPUT:
    
1 . Bibasilar opacities likely a combination of atelectasis and possibly trace pleural effusions . 2 . If clinically indicated a repeat frontal and lateral radiograph with normal positioning would provide a more complete evaluation .
