Title: October 2013 – Marked Interval Change in Bone Density of the Femoral Neck

65 year old Caucasian female, 61” tall, 248 pounds, BMI = 46.85.  Bone density scan for estrogen deficiency in 2007 was normal.  Repeat scan in 2009 found a 21% increase in bone density at the femoral neck.  Both scans were completed on the same Hologic Discovery W.  Patient is taking calcium supplements and a multiple vitamin, but is not taking any other bone-active medications.

















  • The interval change between 2007 and 2009 was -0.6% (not significant) in the total hip and +21% at the femoral neck (well above the LSC at this center).  What could explain this discrepancy?
