My BMD Results from 2007 to 2024

2007 (my first DXA scan; osteoporosis diagnosis)

My T-score at the lumbar spine was -3.0 (-2.0 at L1, -2.7 at L2, -3.4 at L3 and -3.8 at L4).

My T-score at the left hip was -2.2 (-2.8 at neck, -2.0 at troch, -1.9 at inter).

My BMD results in g/cm2 were 0.712 at the spine (L1-L4), 0.53 at the left hip (neck), and 0.670 at the left hip (total).

2009 My second scan was done 07/06/09 after the following treatment: Fosamax 70 mg weekly from 06/18/07 to 12/24/07, two capsules Doctor's Best Strontium Bone Maker daily from 01/21/08 to 07/06/09.

Spine (L1-L4): BMD 0.749, T-Score -2.7

Lt. Hip (neck): BMD 0.563, T-Score -2.6

Lt. Hip (total): BMD 0.739, T-Score -1.7

2013 (4 years from previous scan; scores in osteopenia range)

0.871 g/cm2 at the spine from L1- L4 (T-score -1.6)

0.692 g/cm2 at the left femoral neck (-1.4 T-score),

0.775 g/cm2 at the left total hip (-1.4 T-score).

2016 (BMD scores improved but still in osteopenia range)

Spine: Total BMD of the spine (L1-4) is 0.897 g/cm2, with a T-score of -1.4.

Left Femoral Neck: BMD is 0.729 g/cm2, with a T-score of -1.1.

Left Total Hip: BMD is 0.812 g/cm2, with a T-score of -1.1.

Compared to the prior study (August 21, 2013), there was a 3% increase in BMD of the lumbar spine and a 5% increase in BMD of the left total hip.

January 2019 (Spine, left total hip, right total hip, right femoral neck show normal BMD; left femoral neck in osteopenia range)

Compared to the prior study, there has been 9% increase in spine density, 6% increase in left total hip density, but no change in left femoral neck density.

August 2022 (showed normal BMD at all sites)

November 2024. The 2024 scan included a TBS, which found 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.

Originally (2007), my worst BMD scores were for my spine. My most recalcitrant area now is my left femoral neck.

DXA Scan of 18 August 2022 Showing Normal Density

Below is my recent axial DXA performed on a Horizon Prologic Wi DXA scanner and showing NORMAL BONE DENSITY! Even if my scores are lower by half due to strontium use, the changes are phenomenal. Fifteen years ago, I was diagnosed with osteoporosis. My scans have gotten progressively better since I began taking strontium citrate 14 years ago. For my next DXA scan, I will ask that a Trebecular Bone Score (TBS) be included.Trabecular bone score (TBS) uses standard lumbar spine DXA imaging to assess bone texture inhomogeneity (that is, the number of filled versus unfilled voxels) in order to gauge bone quality and fracture risk. Strontium will not affect TBS as it does DXA. 

EXAM:  DXA AXIAL 8/18/2022

 INDICATION:  Postmenopausal.

 COMPARISON: 1/8/2018

 

FINDINGS:

 

Spine:  Total BMD of the spine L1-4 is 1.030 g/cm2, with a T-score of -0.2 and a Z-score of 2.2.

Left Femoral Neck: BMD is 0.741 g/cm2, with a T-score of -1.0  and a Z-score of 1.1.

 

Left Total Hip: BMD is 0.856 g/cm2, with a T-score of -0.7 and a Z-score of 1.0.

 

Right Femoral Neck: BMD is 0.752 g/cm2, with a T-score of -0.9 and a Z-score of 1.2.

Right Total Hip: BMD is 0.907 g/cm2, with a T-score of -0.3 and a Z-score of 1.5.

Spine density increased 5.2%. Left hip density decreased 1%. Right hip density increased 0.9%. These percent change findings may be inaccurate as exam was performed with different technique.

FRAX evaluation calculates 10-year probability of fracture:

 Major Osteoporotic: 7.9%%

 Hip: 1.3%%

IMPRESSION:

 Based on BMD, diagnosis is consistent with normal density.

 Follow up with DEXA and TBS: As needed.

WHO CRITERIA FOR T-SCORES:

 < or = -2.5 = osteoporosis

 < -1.0 and -2.5 = osteopenia

 > or = -1.0 = normal density
