Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lung volumes are low . This limits assessment of the lung bases . Streaky and linear opacities in the lung bases most likely reflect atelectasis . No focal consolidation is demonstrated . No pleural effusion or pneumothorax is identified . Heart size is normal . The aorta remains tortuous and diffusely calcified . The pulmonary vasculature is normal . Partially imaged is cervical spine fusion hardware as well as 2 screws within the left proximal humerus . Multiple clips are demonstrated in the right upper quadrant of the abdomen . There are no acute osseous abnormalities .
    OUTPUT:
    
Low lung volumes limit the assessment of the lung bases . Bibasilar airspace opacities likely reflect atelectasis , but repeat exam with improved inspiratory effort is suggested when the patient is able , to further assess the lung bases .
