Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There are relatively low lung volumes . Subtle small nodular opacities noted at the left upper lung and possibly right lung base are nonspecific and of uncertain chronicity , given lack of priors for comparison . Recommend comparison with any prior studies , if none consider nonurgent chest CT for further assessment if clinically appropriate given patient age . Bibasilar atelectasis is seen . More focal lateral right base opacity could be due to scarring but underlying pulmonary nodule or focal consolidation is not excluded . Dedicated PA and lateral views the chest would be helpful for further assessment if / when patient able . No large pleural effusion or pneumothorax . Cardiac silhouette size is top - normal . The aorta is calcified and tortuous . Subtle deformities of several lateral mid to lower right ribs are of indeterminate age , but could be due to prior fractures .
    OUTPUT:
    
Subtle deformities of at least ___ lateral right mid to lower ribs are of indeterminate age , but rib fractures of indeterminate age not excluded . Low lung volumes . Subtle nodular opacities at the left upper lung and right lung base are of unclear clinical significance or chronicity . Recommend comparison with prior studies if available or nonurgent chest CT for further assessment . Bibasilar atelectasis . More focal lateral right base opacity could be due to scarring but underlying pulmonary nodule or focal consolidation is not excluded . Dedicated PA and lateral views the chest would be helpful for further assessment if / when patient able .
