    INPUT: Compared with ___ , the ET and NG tube is been removed . Tracheostomy tube is in place . A G - tube appears to be present . Again seen is moderate to moderately severe cardiomegaly . There has been partial clearing of the retrocardiac opacity . There does appear to be some leftward shift of the mediastinum , which is unchanged . There is upper zone redistribution and diffuse vascular blurring , consistent with CHF , very slightly improved . At the right lung base , there are some hazy , more nodular densities which were not visible on the prior film . Question residua from resolving pulmonary edema . The differential diagnosis could include callus about anterior rib fractures .
    OUTPUT:
    
1 . Moderate to moderately severe cardiomegaly , unchanged . 2 . CHF , with interstitial and question alveolar edema , slightly improved compared with ___ . 3 . Left lower lobe collapse and / or consolidation , also slightly improved . This could include an area of pneumonic infiltrate . 4 . Hazy nodular densities right lung base , newly visible . Question artifact due to resolving pulmonary edema versus callus about anterior rib fractures . Attention to these areas on followup films are requested .
