Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Moderate cardiomegaly is again re - demonstrated , unchanged . Aorta is tortuous and diffusely calcified . Mediastinal and hilar contours are stable . Lung volumes are slightly lower compared to the previous exam , and cause crowding of the bronchovascular structures without overt pulmonary edema . Linear opacities in the right mid and lower lung fields likely reflect areas of atelectasis or scarring . Partially loculated right pleural effusion is small , and accounting for differences in lung volumes is likely unchanged . Right basilar patchy opacity may reflect atelectasis . Trace left pleural effusion may be minimally improved . No pneumothorax is identified . Marked abnormality of both glenohumeral joints with bony remodeling of the femoral heads is re - demonstrated .
    OUTPUT:
    
No substantial interval change from the prior exam other than decreased lung volumes . Continued small partially loculated right pleural effusion and trace left pleural effusion . Right basilar patchy opacity may reflect atelectasis but aspiration or infection is not completely excluded .
