Clinical DEXA Scans: The Gold Standard in Body Composition & Baseline Testing

A DEXA (Dual-Energy X-ray Absorptiometry) Scan is a fast, painless, and highly accurate imaging test that maps your exact body composition. Whether you are optimizing your fitness performance, tracking muscle growth, or preparing for a metabolic reset, understanding your baseline is the first step to real transformation.

Led by board-certified bariatric surgeon Dr. Will Johnson, Bodiatrics utilizes clinical-grade DEXA technology to help patients across North Georgia track progress, identify health risks, and build data-driven, personalized wellness strategies.

Why guess when you can measure? While standard scales only show superficial weight, a DEXA scan reveals the critical data beneath the surface. With metabolic health risks and bone density loss becoming growing concerns, clinical body composition tracking is essential for maximizing longevity, preventing injury, and ensuring safe, sustained fat loss while preserving vital muscle mass.

Beyond the Scale: What a DEXA Scan Reveals

Dual-energy X-ray technology assesses bone density, lean muscle tissue, and body fat with unparalleled, medical-grade accuracy. It eliminates the guesswork of BMI and standard bathroom scales, providing you with a highly detailed physiological map.

Patients and athletes use this data to:

  • Identify precise visceral fat levels (the dangerous, inflammatory fat surrounding internal organs).
  • Track muscle preservation and growth during weight loss, peptide therapy, or strength training regimens.
  • Detect early warning signs for conditions like osteoporosis, cardiovascular disease, and metabolic syndrome.
  • Create a customized biohacking strategy for sustained health, performance, and longevity.

  • ⚠️ Enclosed chamber test
  • ❌ No muscle or bone data
  • ❌ No visceral fat tracking
  • ⚠️ Limited availability
  • 💲 $40–$100

📏 Skinfold Calipers

  • ❌ Low accuracy
  • ⚠️ Depends on technician
  • ❌ No internal fat data
  • ⚠️ Can be uncomfortable

  • 💲 $10–$50

Targeted Baseline Testing at Bodiatrics

We offer two specialized scanning protocols based on your specific health optimization goals:

1. Total Body Composition Analysis
This scan gives you the most accurate, granular overview of your body’s makeup, including:

  • Total body fat percentage and exact regional distribution.
  • Visceral fat levels (a critical indicator of metabolic risk).
  • Lean muscle mass distribution through your arms, legs, and trunk.

Best for: Patients undergoing medical weight loss, elite athletes, fitness enthusiasts, and anyone wanting a highly detailed picture of their physical progress.

2. Clinical Bone Density Assessment
The accepted medical standard for diagnosing osteopenia (low bone mass) and osteoporosis. The report includes two vital scores:

  • T-score: Compares your bone density to that of a healthy young adult.
  • Z-score: Compares your bone density to an age-matched reference group.

Best for: Adults over 50, postmenopausal women, or individuals with a family history of bone density loss seeking preventative care.

What to Expect During Your Visit

A DEXA Scan is entirely non-invasive and requires minimal preparation.

  • Preparation: Avoid calcium supplements for 24 hours before your scan. Wear comfortable clothing without metal zippers, buttons, or hooks.
  • The Procedure: You will lie flat comfortably on the scanning bed for 7 to 10 minutes while the arm passes over your body.
  • Immediate Insights: As soon as the scan is complete, your data is generated, reviewed, and discussed in detail to help you map your next steps.

Decoding Your Data

Here is exactly what you will learn from your comprehensive report:

Body Composition Markers

  • Total Body Fat Percentage: Your exact ratio of adipose tissue relative to healthy baseline levels.
  • Lean Muscle Mass: The precise amount and location of functional muscle tissue throughout your body.
  • Visceral Adipose Tissue (VAT): A vital measurement of the internal fat linked to cardiovascular disease and metabolic dysfunction.

Bone Health Markers

  • T-score: Indicates if your bone density is normal, low (osteopenia), or critical (osteoporosis).
  • Z-score: Identifies whether your bone health is unusual for your specific age demographic.

Why Trust Bodiatrics with Your Metabolic Data?

Data is only as valuable as the medical expertise interpreting it. Dr. Johnson and the Bodiatrics care team don’t just hand you a printout; we help you build an actionable roadmap based on your unique biology.
