Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Rotated positioning . Again seen are sternotomy wires . The cardiomediastinal silhouette appears grossly unchanged . The aorta is calcified and the aortic arch is slightly dilated measuring approximately 4 .2 cm . The rounded contour overlying the right heart border , with thin curvilinear calcifications apparently represents the known dilated lower thoracic aorta . Calcification and suspected dilatation of the abdominal aorta is also noted . There is hazy density overlying the lower left chest . Though much of this may relate to the overlying breast implants , the possibility of retrocardiac density with underlying collapse and / or consolidation and a small left effusion is suspected . There is upper zone redistribution , without overt CHF . The right lung is grossly clear , without focal infiltrate or gross effusion . No pneumothorax detected . An NG type tube is present , tip extending beneath diaphragm , off film . A single surgical clip is seen at the right upper lung laterally . Note is made of fusion hardware in the lumbar spine .
    OUTPUT:
    
Doubt significant change compared with ___ . Suspect left lower lobe collapse and / or consolidation and small left effusion , not significantly changed . If clinically indicated , a lateral view could help to further assess the left lower lobe . The cardiomediastinal silhouette , including dilated , calcified visualized portions of the thoracic aorta are similar to the prior film . The ET tube has been removed . The NG tube extends beneath the diaphragm , off the film .
