Title: June 2013 – Discordance between spine and femur scans and marked discordance between two femur scans

77 year-old white male presents for bone density testing on a GE Lunar Prodigy densitometer. He reports a history of arthritis but is otherwise healthy. Height is 66.5 inches and weight 150 pounds.



  • Based on the spine and femur scans, what is your diagnosis?
  • Is the bone density of the lumbar spine normal?
  • Why may there be such a discrepancy between the right and
    left total mean BMD values?
  • Does the femur discrepancy invalidate the Total Mean Femur BMD?
  • What further evaluation is indicated?
