Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Compared with the prior study and allowing for apparent blurring due to motion on today 's study , there is somewhat more confluent opacity through much of the right lung , suggesting the presence of an alveolar component . Possible small confluent areas scattered in the left lung . No effusion is identified . Bilateral background interstitial changes are similar to the prior film . The cardiomediastinal silhouette is unchanged , with prominence of the ascending and descending aorta . No pneumothorax is detected . Cerclage wire can clips seen over the lower neck .
    OUTPUT:
    
More confluent alveolar opacities apparent on today 's exam , allowing for blurring due to motion . In the proper clinical setting , this could reflect progressive CHF , now with alveolar edema . In the appropriate clinical setting , pneumonic infiltrates , hemorrhage , and ARDS could have a similar appearance . Clinical correlation is therefore requested .
