Below are the results of my latest DXA scan and my first TBS. I am so excited about my TBS showing normal bone microarchitecture!
The only value that was slightly worse than my previous scan of 18 August 2022, was my left femoral neck BMD of 0.728 g/cm2 and a T-score of -1.1 (osteopenia) in 2024, compared to left femoral neck BMD of 0.741 g/cm2 and a T-score of -1.0 (normal density) in 2022.
For almost a year and a half (3/5/2023 through 8/17/2024), I reduced my daily dosage of strontium citrate from 682 mg of strontium per day to 341 mg 4X per week and 682 mg 3X per week. I resumed the full dosage on 8/18/2024.
Impression
Based on BMD criteria, the patient has osteopenia.
Based on the lumbar spine TBS data, the patient has a normal bone microarchitecture compared to the reference population.
The patient's associated BMD and TBS values suggest a moderate resilience to fracture.
Follow up with DEXA and TBS: 2 years
WHO CRITERIA FOR T-SCORES:
< or = -2.5 = osteoporosis
< -1.0 and -2.5 = osteopenia
> or = -1.0 = normal density
TBS scores:
>1.31: normal bone microarchitecture
<1.31 and >1.23: partially degraded microarchitecture
<1.23: degraded microarchitecture
Narrative
EXAM: DXA AXIAL
INDICATION: Postmenopausal. Risk factors for osteoporosis include [advanced age
COMPARISON: 8/18/2022
FINDINGS:
Spine: Total BMD of the spine L1-4 is 1.129 g/cm2, with a T-score of 0.7 and a Z-score of 3.2. The lumbar spine trabecular bone score (TBS) is 1.521.
Left Femoral Neck: BMD is 0.728 g/cm2, with a T-score of -1.1 and a Z-score of 1.1.
Left Total Hip: BMD is 0.842 g/cm2, with a T-score of -0.8 and a Z-score of 1.1.
Right Femoral Neck: BMD is 0.754 g/cm2, with a T-score of -0.9 and a Z-score of 1.3.
Right Total Hip: BMD is 0.900 g/cm2, with a T-score of -0.3 and a Z-score of 1.5.
Diffuse increased 10% in the lumbar spine
FRAX (adjusted for TBS if available) evaluation calculates 10-year probability of fracture:
Major Osteoporotic: 8.7%
Hip: 1.7%
