Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: AP upright and lateral views of the chest were provided . The lung volumes are low and the patient is rotated to her right , which limits the evaluation . Linear densities in the left and right lower lungs likely represent areas of subsegmental atelectasis . There is no convincing evidence of pneumonia or CHF . No pleural effusion or pneumothorax is seen . Heart size appears relatively stable , and the mediastinal contour is difficult to assess given rotation to the right . Degenerative changes are again noted at bilateral shoulders . No free air below the right hemidiaphragm . No large effusions are seen .
    OUTPUT:
    
Limited study with lower lung subsegmental atelectasis . Otherwise grossly unremarkable .
