Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: PA and lateral chest views were obtained with patient in upright position . Analysis is performed in direct comparison with the next preceding similar study of ___ . The heart size is normal and no configurational abnormality is identified . Thoracic aorta of normal dimension and only mildly elongated . No local contour abnormalities are identified . The pulmonary vasculature is not congested . There exists , however , an irregular peripheral vascular distribution coinciding with hyperinflation of mostly the basal lung portions with low positioned and flattened diaphragms . Some linear basal densities are identified and consistent with peripheral atelectasis but there is no evidence of any new acute parenchymal infiltrates anywhere in the lungs when comparison is made with the preceding examination . Findings are consistent with rather advanced COPD , emphysema , but there is no evidence of pulmonary vascular congestion or acute infiltrates . The heart size is well within normal limits in this elderly female patient . No pneumothorax is identified in the apical area and the skeletal structures are remarkably well preserved with no evidence of vertebral body compression and the kyphotic curvature of the thoracic spine is only mildly accentuated .
    OUTPUT:
    
No acute new pulmonary or cardiovascular abnormalities .
