Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There is platelike opacity in the right mid zone , new compared with ___ . The appearance is more suggestive of platelike atelectasis at an an acute infiltrate , is new compared with ___ . It is associated with slight retraction of the minor fissure . Otherwise , no focal opacities are identified . Background hyperinflation and minimal bibasilar atelectasis is again noted . Cardiomediastinal silhouette is stable , with heart size at the upper limits of normal . The aorta is calcified and slightly tortuous , similar to prior . Again seen is rightward deviation of the trachea , slightly more pronounced than in ___ . This was attributed to a known left thyroid nodule on the prior study . Minimal blunting of the lateral left costophrenic angle is new compared with ___ . No CHF or gross effusion . Vertebral bodies are poorly delineated , likely due to osteopenia . Mild thoracic vertebral body wedging is probably similar to the prior study . Background degenerative changes are also present .
    OUTPUT:
    
Platelike density in the right upper zone . This most likely represents platelike atelectasis , but early changes of a pneumonic infiltrate would be difficult to exclude . Otherwise , no focal infiltrates , CHF or gross effusion . Minimal blunting of left costophrenic angle is noted . Rightward deviation of the trachea is again noted , slightly more pronounced . By report , the patient has an associated left thyroid nodule . Clinical correlation is requested .
