Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: There is a slightly suboptimal inspiratory effort and low lung volumes . Allowing for changes due to this , the cardiomediastinal silhouettes are stable and within normal limits . The thoracic aorta is mildly tortuous . The bilateral hila are unremarkable . The lungs are clear , although subtle hazy opacity at the lung bases is likely reflective of crowding of bronchovascular structures in the setting of low lung volumes . There is no focal lung consolidation . There is no pneumothorax or pleural effusion . Again seen are multifocal osseous abnormalities involving several bilateral ribs , likely reflecting myelomatous involvement , unchanged from prior .
    OUTPUT:
    
1 . Low lung volumes . Basilar atelectasis . No focal pneumonia . 2 . Multifocal osseous abnormalities involving several ribs , unchanged from prior , likely reflective of myelomatous involvement .
