Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lung volumes are lower compared to the prior examination . Heart size is accentuated as result , appearing mildly enlarged but similar to the previous examination . The aorta remains mildly tortuous . Mediastinal and hilar contours are unremarkable . Crowding of bronchovascular structures without overt pulmonary edema is present . Linear and patchy opacities in the lung bases appear slightly worse in the interval , most likely reflective of worsening atelectasis . No focal consolidation , pleural effusion or pneumothorax is present . Mild hypertrophy changes are seen in the lower thoracic spine . Fusion hardware within the lumbar spine is incompletely assessed . A left PICC tip terminates in the mid SVC .
    OUTPUT:
    
Lower lung volumes with increased patchy and linear opacities in the lung bases , likely worsening atelectasis .
