Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There are curvilinear areas of parenchymal opacity in the right mid zone and an additional irregular opacity in the left base posteriorly . These are of indeterminate acuity . There are opacities that are somewhat similar in distribution seen on the ___ chest x-ray , but the distribution is not identical hand both opacities are larger and more pronounced on today 's examination . There is mild cardiomegaly and mild prominence of the cardiomediastinal silhouette . Although cardiac silhouette itself is probably not significantly changed , the mediastinal prominence is new and not clearly fully accounted for by technique . Within the limits of plain film radiography , no hilar adenopathy is detected . No CHF , air bronchograms or effusions are identified . Mild elevation of the right hemidiaphragm is more pronounced than in ___ . Mild left greater right apical pleural thickening is also more pronounced . Probable embolization material seen projecting over the upper abdomen distal left of midline , similar to ___ .
    OUTPUT:
    
Opacities at the right base and posterior left lower lobe are new or significantly changed compared with ___ . These are of indeterminate acuity and not fully characterized by a chest x-ray . The differential includes infectious , inflammatory and neoplastic processes . Further assessment with chest CT is recommended . Prominence of the mediastinum appears increased compared with ___ . Has there been a change in body habitus to account for this ? Attention to this area at the time of the chest CT is recommended . Mild cardiomegaly . Mild left - greater - than - right apical pleural thickening , slightly increased compared with ___ . Embolization in the upper abdomen , likely in the region of the left gastric artery .
