Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Single AP upright portable view of the chest . External artifact overlying the right chest makes evaluation slight suboptimal . Lung volumes are relatively low . There is prominence of the bilateral pulmonary vasculature , worrisome for pulmonary edema . More focal areas of patchy opacity in the right lung as compared to the left could be due to asymmetric pulmonary edema , but infection or aspiration or not excluded in the appropriate clinical setting . No large pleural effusion is seen although a small pleural effusion is difficult to exclude . There is no evidence of pneumothorax . Cardiac silhouette is top - normal to mildly enlarged . Mediastinal contours are grossly unremarkable .
    OUTPUT:
    
Low lung volumes . Prominence of the pulmonary vasculature suggests pulmonary edema ; patchy areas of airspace opacity projecting over the right lung as compared to the left could relate to asymmetric pulmonary edema , but infection or aspiration are not excluded .
