Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lung volumes are low . Bibasilar opacities may represent dependent atelectasis . However , there are also air bronchograms at the medial right lung base which should be followed closely to exclude aspiration . No pleural effusion or pneumothorax . Cardiomediastinal silhouette is within normal limits . No acute osseous abnormalities identified . No subdiaphragmatic free air is detected .
    OUTPUT:
    
Low lung volumes with bibasilar atelectasis . The presence of air bronchograms would warrant close follow - up to exclude aspiration , however the subsequent abdomen CT showed no consolidation in the lower lungs .
