Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Cardiomediastinal contours are normal . Lungs are grossly clear on the frontal view . Questionable opacity overlying the lower thoracic spine on the lateral view without silhouetting of the diaphragm contours may be due to superimposition of normal structures due to suboptimal positioning on the lateral radiograph Limited assessment of the upper abdomen is within normal limits .
    OUTPUT:
    
No definite pneumonia . If clinical suspicion for infection persists , repeat lateral radiograph with improved positioning may be helpful to fully exclude a lower lobe pneumonia .
