Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Assessment of fine detail in the lower lungs and chest is considerably limited by overlying soft tissues . Allowing for this , there is increased density over the lower half of both lung bases , though this could represent artifact due to overlying soft tissues , the possibility of parenchymal opacity can not be excluded . There is faint suggestion of bibasilar air bronchograms . There is upper zone redistribution . The possibility of more extensive CHF or of small effusions would be difficult to exclude on this view . The base of the left lung is not well evaluated on this study .
    OUTPUT:
    
Limited exam , as detailed above . Cardiomegaly , similar to the prior film . Upper zone redistribution . The possibility of CHF , focal basilar consolidations , or small effusions can not be excluded . If there is a concern for focal consolidation at the lung bases , then PA and additional lateral view may help for further evaluation of the lung bases .
