Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Heart size is at the upper limits of normal . Within the limits of plain film radiography , no hilar or mediastinal lymphadenopathy is detected . No CHF , focal infiltrate , effusion , or pneumothorax is detected . In the mid thoracic spine , there is suggestion of severe disk space narrowing at the T7 - 9 levels with very subtle right convex curvature in this region . No obvious vertebral body compression is detected . No spondylolisthesis is seen . The sternum is partially obscured on the lateral view by overlying soft tissues , but is grossly unremarkable . The sternoclavicular joints are minimally asymmetric , though this may relate to slight scoliotic curvature . Incidental note is made of piercings in both breasts .
    OUTPUT:
    
1 . No acute pulmonary process identified . 2 . Focal disc space narrowing in the thoracic spine , at T7 - 9 , with probable subtle right convex curvature at that level .
