Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lung volumes are low . Heart size is normal with a left ventricular predominance . Aorta is slightly unfolded . Widening of the right paratracheal stripe may reflect tortuous vessels but lymphadenopathy is not excluded . No pulmonary edema is present . Elevation of the right hemidiaphragm is of unknown chronicity . Bibasilar streaky opacities likely reflect atelectasis . No pleural effusion or pneumothorax is identified . No acute osseous abnormalities are visualized .
    OUTPUT:
    
Low lung volumes with bibasilar atelectasis . Elevation of the right hemidiaphragm , of unknown chronicity . Widened right paratracheal stripe could reflect tortuous vessels though underlying lymphadenopathy is not excluded . Consider repeat chest radiographic examination with improved inspiratory effort or chest CT .
