我刚要求测骨密度，本人52，我正琢磨半天不是太明白我的结果是好是坏，请帮我看看，谢谢。
FINDINGS:
RIGHT FEMUR (neck):
The bone mineral density is 0.779 gm/cm sq.
Percentage of young normal mean is 75%.
T-score is -1.9.
Percentage age-matched mean is 86%.
Z-score is -0.9.
COMMENT:
The right femur total demonstrates an interval change of -2.0% from the most recent previous/baseline study of 1/23/2018, which is not a statistically significant change.
LEFT FEMUR (neck):
The bone mineral density is 0.782 gm/cm sq.
Percentage of young normal mean is 75%.
T-score is -1.8.
Percentage age-matched mean is 87%.
Z-score is -0.9.
COMMENT:
The left femur total demonstrates an interval change of -5.1% from the most recent previous/baseline study of 1/23/2018, which is a statistically significant change.
LUMBAR SPINE(L1-L4):
The bone mineral density is 1.139 gm/cm sq.
Percentage of young normal mean is 97%
T-score is -0.3.
Percentage age-matched mean is 104 %.
Z-score is 0.4 .
COMMENT:
The lumbar spine L1-L4 demonstrates an interval change of -5.0% from the most recent previous/baseline study of 1/23/2018, which is a statistically significant change.
10 year probability of fracture:
Major osteoporotic: 3.6 %
Hip: 0.4 %
Population: USA (Asian)
Based on DualFemur: Neck Right BMD
