DEXA Body Composition Scans in Knoxville, TN
Smooth Wrinkles. Restore Volume. Look Refreshed—Not Overdone.
A scale cannot tell the full story. A DEXA body-composition scan offers a detailed look at lean mass, fat mass, fat distribution, and bone density so you and your clinician can make decisions with more context.
At RMD Longevity Institute, DEXA can serve as a useful baseline for patients focused on strength, metabolic health, weight-management progress, healthy aging, or bone health. The scan is quick, noninvasive, and does not require a workout, injection, or recovery time.
What a Knoxville DEXA Body Composition Scan Measures
• Lean mass and fat mass throughout the body
• Visceral-fat estimate, where available through the selected scan protocol
• Bone mineral density when ordered and clinically appropriate
• Right-to-left and regional body-composition comparisons
Why DEXA Body Composition Data Matters Beyond Body Weight
Two people can have the same weight and very different body composition. Tracking changes in lean tissue and fat distribution over time may make nutrition, training, weight-management, and healthy-aging conversations more meaningful. Results are not a diagnosis by themselves; your clinician will interpret them with your history and goals.
WHAT DOES A DEXA BODY COMPOSITION SCAN MEASURE?
A DEXA body composition scan provides detailed measurements that go beyond weight and BMI. It can show total body fat, lean muscle mass, visceral fat, regional fat distribution, and bone density. This information creates a more accurate baseline for your health, fitness, and longevity goals.
WHY BODY COMPOSITION MATTERS MORE THAN THE SCALE
Two people can weigh the same but have very different levels of lean muscle, body fat, and visceral fat. A DEXA scan helps reveal what the scale cannot, giving you more useful context for improving metabolic health, maintaining muscle, supporting bone health, and tracking progress over time.
HOW YOUR DEXA SCAN RESULTS GUIDE YOUR NEXT STEPS
Your results can help identify practical areas of focus, such as building lean muscle, reducing visceral fat, improving nutrition, or monitoring bone density. Your provider will help place the data in the context of your health history and goals, then recommend thoughtful next steps for your personalized plan.
IS A DEXA BODY COMPOSITION SCAN SAFE?
Yes. A DEXA scan uses a very low level of radiation and is a noninvasive way to measure body composition and bone density. You remain fully clothed and comfortable during the scan, with no needles, contrast dye, exercise, or recovery period required. Your provider can answer any personal safety questions before your appointment.
DEXA SCAN VS. BMI: WHAT IS THE DIFFERENCE?
BMI uses only height and weight, so it cannot distinguish between muscle, body fat, and bone mass. A DEXA body composition scan provides a much more detailed view by measuring lean mass, fat mass, visceral fat, and bone density. This makes it especially useful for people whose health or fitness progress is not reflected accurately by BMI alone.
WHAT IS VISCERAL FAT AND WHY DOES IT MATTER?
Visceral fat is fat stored deeper in the abdomen around internal organs. Unlike subcutaneous fat, which sits just beneath the skin, higher levels of visceral fat can be associated with metabolic-health concerns. A DEXA scan can help estimate visceral fat so you and your provider can use that information as part of a more complete, proactive health strategy.
Who May Be a Candidate for DEXA Body Composition Testing?
DEXA may be considered by adults who want a detailed baseline or who are monitoring a clinician-guided health plan. Tell us if you are pregnant or think you may be pregnant, have had recent contrast imaging, or have questions about whether the scan is appropriate.

You don’t need to know what you need—we guide you.
HOW TO PREPARE FOR YOUR DEXA SCAN
Wear comfortable clothing without metal zippers, buttons, or jewelry whenever possible. Depending on your appointment, your care team may also provide guidance about meals, exercise, supplements, or other preparation steps beforehand. Following those instructions helps ensure the clearest, most consistent results.
WHAT HAPPENS DURING A DEXA BODY COMPOSITION SCAN
During your DEXA scan, you will lie comfortably and remain still on a padded table while the scanner passes over your body. The process is noninvasive and does not require needles, exercise, or recovery time. The scan measures key body-composition data, including fat mass, lean mass, and bone density.
UNDERSTANDING YOUR DEXA SCAN RESULTS
Your results provide a detailed baseline that goes beyond the number on a scale. Your provider can explain how your body-fat percentage, lean muscle distribution, visceral fat, and bone-density measurements relate to your goals. Together, you can use these insights to guide a more personalized plan for nutrition, strength training, metabolic health, recovery, and ongoing progress tracking.
WHEN TO REPEAT YOUR DEXA BODY COMPOSITION SCAN
A follow-up DEXA scan can help you measure meaningful changes over time and adjust your health plan with real data. Your ideal schedule depends on your starting point, goals, and the recommendations of your provider. Many patients use periodic scans to track changes in lean muscle, body fat, visceral fat, and bone density as they focus on nutrition, strength training, metabolic health, or healthy aging.
Frequently Asked Questions
Is DEXA the same as a bone-density test?
DEXA technology can be used for bone-density testing and for body-composition analysis. Your order and report determine which measurements are included.
How often should I repeat a scan?
Timing depends on your goals and clinician’s guidance. Repeating it too soon may not show a meaningful change.
Does a DEXA scan hurt?
No. It is noninvasive and typically painless.
