Hypothesis
A high percentage of VFA's would include the abdominal aorta if the technician was specifically instructed to include this region during VFA acquisition.
Conclusion
VFA imaging can detect radiographic AAC, an important cardiovascular disease risk factor, while assessing for vertebral fractures.
Supporting Evidence
- 90% of the VFA images were evaluable for AAC.
- The intraclass correlation coefficient between VFA and radiographic scores was 0.80.
- VFA imaging exposes patients to significantly less radiation than standard radiographs.
Takeaway
Doctors can use special images taken for bone health to also check for heart problems in older women.
Methodology
The study involved 174 postmenopausal women who underwent bone densitometry and imaging to assess abdominal aortic calcification.
Potential Biases
Participants may have been healthier than the general population, potentially skewing results.
Limitations
The prevalence of AAC was lower than expected, and results are only applicable to post-menopausal women.
Participant Demographics
Postmenopausal women aged 55 and older, primarily white and black.
