Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Mild enlargement of the cardiac silhouette is again noted with left ventricular predominance . The aorta is tortuous but unchanged mediastinal and hilar contours are similar . Pulmonary vasculature is not engorged . Lung volumes are low with streaky and linear opacities in the lung bases compatible with atelectasis . No focal consolidation , pleural effusion or pneumothorax is present . The osseous structures are diffusely demineralized with compression deformity of a vertebral body at the thoracolumbar junction appearing unchanged .
    OUTPUT:
    
1 . Low lung volumes with bibasilar atelectasis . 2 . Diffuse osteopenia with compression deformity at the thoracolumbar junction appearing unchanged . Please note that the assessment for compression fractures is limited given the presence of osteopenia and if there is high concern for a vertebral body fracture , CT is recommended .
