    INPUT: Assessment is limited by patient positioning and rotation . Heart size appears mildly enlarged . Mediastinal contours are grossly unremarkable . There is no overt pulmonary edema , nor is there a pleural effusion or pneumothorax . Lung volumes are low . There appear to be patchy opacities in the lung bases which are nonspecific , and may be reflective of infection or aspiration . No acute osseous abnormality is detected .
    OUTPUT:
    
Limited exam . Probable patchy opacities in the lung bases which are nonspecific , potentially reflective of infection or aspiration in the correct clinical setting . Consider repeat PA and lateral views of the chest when the patient is able to be positioned for these exams
