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

FRAX Identifies Women with Prevalent Asymptomatic Vertebral Fractures

Abstract

Background

A Moroccan model for the FRAX tool to determine the absolute risk of osteoporotic fracture at 10 years has been established recently. The study aimed to assess the discriminative capacity of FRAX in identifying women with prevalent asymptomatic vertebral fractures (VFs).

Methods

We enrolled in this cross-sectional study 908 post-menopausal women with a mean age of 60.9 years ±7.7 (50 to 91) with no prior known diagnosis of osteoporosis. Subjects were recruited from asymptomatic women selected from the general population. Lateral VFA (vertebral fracture assessment) images and scans of the lumbar spine and proximal femur were obtained using a GE Healthcare Lunar Prodigy densitometer. VFs were defined using a combination of Genantsemiquantitative (SQ) approach and morphometry. We calculated the absolute risk of major fracture and hip fracture with and without bone mineral density (BMD)using the FRAX website.The overall discriminative value of the different risk scores was assessed by calculating the areas under the ROC curve (AUC).

Results

VFA images showed that 179 of the participants (19.7%) had at least one grade 2/3 VF. The group of women with VFs had a statistically significant higher FRAX scores for major and hip fractures with and without BMD, and lower weight, height, and lumbar spine and hip BMD and T-scores than those without a VFA-identified VF. The AUC ROC of FRAX for major fracture without BMD was 0.757 (CI 95%; 0.718-0.797) and 0.736 (CI 95%; 0.695-0.777) with BMD, being 0.756 (CI 95%; 0.716-0.796) and 0.747 (CI 95%; 0.709-0.785), respectively for FRAX hip fracture without and with BMD. The AUC ROC of lumbar spine T-score and femoral neck T-score were 0.660 (CI 95%; 0.611-0.708) and 0.707 (CI 95%; 0.664-0.751) respectively.

Conclusion

In asymptomatic post-menopausal women, the FRAX risk for major fracture without BMD had a better discriminative capacity in identifying the women with prevalent VFs than lumbar spine and femoral neck T-scores suggesting its usefulness in identifying women in whom VFA could be indicated.
