Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Diffuse opacities through both lungs are noted , but may be accentuated by supine positionoing and low lung volumes , as there is no correposnding opacity in the upper portion of the lungs seen on the conteporaneous c- spine CT . Low inspiratory volumes may also account for slight prominence of the cardiomediastinal silhouette . The heart is not enlarged . No supine film evidence of pneumothorax identified and no gross effusion . No apical capping is identified . No rib fracture detected on this lung - technique film .
    OUTPUT:
    
1 ) No evidence of pneumothorax detected . 2 ) Diffuse bilateral lung opacities . However , this may be an artifact due to technique . If clinically indicated , a repeat CXR in upright position with improved inspiration , may help for further assessment .
