Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Study is limited due to patient rotation . The heart size remains top normal in size . The aorta demonstrates diffuse calcifications . Mediastinal and hilar contours are grossly likely unchanged . The pulmonary vascularity is not engorged . There appears to be bronchial wall thickening noted in the left mid lung field . Lungs remain hyperinflated , compatible with underlying COPD . Streaky opacities in the lung bases likely reflect atelectasis . No focal consolidation is visualized . There is no pleural effusion or pneumothorax . Diffuse demineralization of the osseous structures is present with a mild wedge compression deformity of a mid thoracic vertebral body , unchanged , and old left rib cage deformities .
    OUTPUT:
    
COPD with bronchial wall thickening in the left mid lung field suggestive of bronchitis . Bibasilar atelectasis .
