As Mrs Scott is experiencing regular falls and has a family history of osteoporosis, you feel it is relevant to investigate her fracture risk by measuring bone density.  Thankfully, Mrs Scott's results were within normal range: results at hip (femoral neck): T = 0; Z = -0.5, and spine T=-0.5 Z=1 (normal range T score >= -1; normal range Z score between -2 and +2).
