As health and fitness technology rapidly evolves, few diagnostic tools have received as much universal endorsement as the DEXA scan (Dual-Energy X-ray Absorptiometry). Recognized for its clinical precision, DEXA is supported by medical experts, research institutions, athletic performance specialists, and public health organizations.
This article highlights the key figures and entities that advocate for DEXA and provides their insights on why it remains the gold standard for bone density and body composition analysis.
1. National Osteoporosis Foundation (NOF)
The NOF has long promoted DEXA as the most reliable way to assess bone health and fracture risk.
"A bone density test, like a DEXA scan, is the only way to diagnose osteoporosis before a broken bone occurs."
— National Osteoporosis Foundation
Their guidelines recommend DEXA scans for all women over 65 and younger individuals with risk factors for osteoporosis.
2. Dr. Andrea Singer, MD – MedStar Georgetown University Hospital
As Chief Medical Officer at NOF and a leading voice in osteoporosis research, Dr. Andrea Singer consistently emphasizes the importance of early detection via DEXA.
“DEXA scans allow us to detect bone loss early—before a patient suffers a fracture. It’s a cornerstone of preventive care.”
— MedStar Health Profile
Her advocacy underscores the scan’s dual role in both diagnosis and prevention.
3. American College of Sports Medicine (ACSM)
In performance and training contexts, DEXA is supported by the ACSM as a scientifically validated method for tracking fat and lean tissue changes.
“DEXA scans provide segmental data that no other body composition technology can match. They are invaluable for monitoring training outcomes.”
— ACSM Blog on Body Composition
Athletes and trainers rely on this precision to fine-tune strength and conditioning programs.
4. Dr. Layne Norton, PhD – Nutritional Scientist and Fitness Coach
A popular voice in evidence-based fitness and nutrition, Dr. Layne Norton publicly endorses DEXA for accurate body composition assessments.
“Most body fat tracking tools are wildly inconsistent. If you want real data, go get a DEXA scan. It’s the only method I trust for body comp progress.”
— Layne Norton via Twitter
Norton’s influence spans both the academic and fitness communities, making his endorsement impactful.
5. International Society for Clinical Densitometry (ISCD)
The ISCD, the professional society dedicated to skeletal health and bone densitometry, certifies clinicians in DEXA interpretation and sets global guidelines.
“DEXA remains the most accurate and reproducible method for assessing bone mineral density. It is central to clinical decision-making in skeletal health.”
— ISCD Official Guidelines
They are instrumental in maintaining the integrity and advancement of DEXA technology worldwide.

Conclusion: A Trusted Tool Backed by Science and Experience
From top medical organizations to elite sports trainers and academic researchers, the consensus is clear: DEXA is not only the most accurate body measurement tool—it’s also the most trusted.
Whether you’re a patient trying to understand your bone health, a clinician tracking therapeutic outcomes, or an athlete measuring training gains, DEXA offers the consistency, precision, and credibility that other technologies lack.
With endorsements from trusted voices in medicine and fitness, DEXA continues to set the standard.
