DEXA body composition scans in Sandy, Utah.

See beyond the bathroom scale with a detailed view of body fat, lean mass, visceral fat, bone density, and body symmetry.

A clearer baseline

The most complete picture of what your body is made of.

At Revitalize, we use cutting-edge technology to help determine your goals around fitness, weight loss, longevity, and functional life span. DEXA body composition analysis gives you a detailed baseline and a consistent way to track how your body changes over time.

What to expect

A quick scan. A detailed view.

Monitoring weight alone does not show how muscle, fat, and bone density are changing. DEXA separates those measurements so you can track what is actually happening.

Dexa scan

The technology

The device uses dual low-power X-ray beams to distinguish bone mineral, lean tissue mass, and fat mass. The full-body image and analysis come from the differences between bone, fat, and lean tissue density. DEXA scans involve a small amount of radiation.

Patient consultation in a medical clinic

Your appointment

After measuring your height and weight, the technician positions you for the scan. The C-arm moves over your body for roughly six minutes. Afterward, we review your results and discuss next steps connected to your goals.

Why it matters

What a DEXA scan tells you.

Whether your goal is to lose, gain, or maintain weight, a DEXA scan breaks down total body fat percentage, lean tissue mass, bone health and density, and subcutaneous versus visceral fat mass.

Feet on a bathroom scale

Look beyond the bathroom scale

Weight fluctuates through the day, and during a caloric deficit the body can draw energy from muscle mass instead of fat mass. A DEXA scan shows where muscle and fat tissue actually sit, including visceral adipose tissue that is invisible to the eye, so you can track change over time.

BMI compared with DEXA body composition analysis

BMI vs. DEXA

BMI is calculated from height and weight alone, so two people at the same weight can have very different body compositions. A DEXA analysis distinguishes fat from lean mass in each region of the body for a more accurate picture.

Your report

Every metric, explained.

Your report includes a complete breakdown of body composition by region, as well as population comparisons for each metric.

Total body fat percentage

The percent of your body composed of fat. It shifts with both the amount of fat and the amount of lean tissue mass you carry.

Fat mass index (FMI)

Fat relative to height. More accurate than BMI because it calculates only the fat you carry, not total weight.

Android to gynoid ratio

Where fat is stored: around the stomach and mid-section, or around the hips. Ideal values are believed to be less than 0.8 for women and 1.0 for men.

Visceral fat (VAT)

Mass, volume, and area of the fat stored around your organs. A VAT area above 100 cm² has been shown to be associated with increased risk of metabolic syndrome and coronary heart disease.

Appendicular lean mass index

Lean mass in the arms and legs relative to height. ALMI is an important indicator of overall health and is strongly correlated with longevity, and we work to keep patients in the top quartile for their age group.

Bone density

How dense your bones are, used to assess risk of osteopenia and osteoporosis. The Z-score compares you with people of similar age and body size; the T-score compares you with a 30-year-old. Anything higher than -1.0 is considered normal.

How to prepare

Simple prep, consistent results.

A DEXA scan requires very little preparation. A few small details keep your measurements comparable from one scan to the next.

What to wear

Light, comfortable, form-fitting clothing such as gym attire is best. Do not wear metal or jewelry, and choose clothing free of underwires, belts, snaps, fasteners, and zippers. Loose-fitting sweats should also be avoided.

Before you arrive

Skip calcium supplements for 24 hours before testing. Fasting for three hours is recommended while staying hydrated, and avoid vigorous exercise for four to six hours before your scan.

Tell your technician

Let the technician know ahead of time if you have any metal in your body so it can be accounted for in the analysis. Wait seven days after a CT with contrast. If you suspect you could be pregnant, do not get a DEXA scan.

If you are under 18 years of age, pregnant, or unable to stay still for six minutes, you are not eligible for a DEXA scan.

Body composition 101

What we measure, and why it matters.

Body fat, also called adipose tissue, is connective tissue distributed throughout the body that helps control metabolism by releasing hormones. Enough fat mass is necessary for vital functions, while excess can be harmful, and where it sits matters as much as how much there is.

Subcutaneous fat illustration

Subcutaneous fat

The layer of fat just beneath the skin, commonly accumulating in the back, waist, hips, thighs, and buttocks. It cushions joints and bones, but risk for adipose-related disease increases when too much is present.

Visceral adipose tissue illustration

Visceral adipose tissue

White fat that accumulates deep in the abdominal cavity, wrapping around the digestive organs, pancreas, intestines, liver, and heart. It is not visible to the naked eye, and elevated levels are closely linked to metabolic syndrome.

Bone density illustration

Bone density

The concentration of minerals in your bones, mainly calcium and phosphorus. A bone density test predicts fracture likelihood and can identify osteopenia or osteoporosis, conditions we track and treat with our patients.

Adipose tissue illustration

Adipose tissue

Adipose tissue grows as fat cells expand in size. Dieting and other weight-loss approaches reduce cell size rather than cell count. White, brown, and beige fat each perform different functions in the body.

Context

What is a normal body fat percentage?

Age and height both influence how many pounds of lean mass and fat a person carries, so we use body fat percentage to make each person's data comparable when assessing whether fat mass is healthy.

National comparison data

DEXA is the only body composition tool that compares your results against a large-scale database of population scans. You will see how your body fat percentage and bone density compare with national averages for people of the same age, gender, and race. Comparisons are based on the National Health and Nutrition Examination Survey (NHANES).

How often should you scan?

DEXA scans are accurate, but their real value is precision: the ability to track small and large shifts in body composition over time. How often you test depends on how strict your training and nutrition are.

Start here

A baseline scan

Getting a baseline DEXA is worthwhile for any adult regardless of fitness level. The accuracy of the scan is what lets follow-up scans show precise change over time.

Every 3 to 6 months

Actively changing

If you are beginning a new exercise program, preparing for a race, cutting for a show, or working to improve overall health, we may advise testing every three to six months depending on your training level and timeline.

Every 6 to 9 months

Maintaining

If your goal is to maintain your current body composition, we advise testing every six or nine months. Always test on the same machine so your scans stay comparable.

Common questions

DEXA questions, answered.

What is a DEXA body composition analysis?

Body composition measurement with Dual-Energy X-ray Absorptiometry looks beyond weight and BMI to determine body fat distribution. DEXA uses small amounts of radiation to produce a whole picture of the body's fat mass, non-fat mass, and bone mass, including regional results for the arms, legs, android (waist), gynoid (hips), and visceral tissue.

What should I expect during the scan?

A DEXA scan is quick and pain-free. The machine has an open design, so most patients lie comfortably without feeling claustrophobic. You will store metal jewelry and objects in a bin, we measure your height and weight, and then the scan itself takes about six minutes. Afterward you receive a multi-page printout with your measurements, percentages, mass, and images.

How long does a DEXA appointment take?

The appointment is typically 15 to 20 minutes, depending on how many questions you have about your results and the ways to improve them.

How much does a DEXA scan cost?

One scan is $75. A two-scan package is $141, and a four-scan package is $241.

Should I eat before the exam?

It is best practice to fast for three hours before your scan for the most accurate results, while still staying hydrated.

How do I read my results?

We review the DEXA body composition analysis with you and send you home with an interpretation sheet covering all of the metrics and what they mean.

How often should I get scanned?

We recommend a DEXA scan every three to six months, depending on your goals and the intensity of your training plan. Many patients purchase a package to track progress over time.

Who should not get a DEXA scan?

If you are under 18 years of age, pregnant, or unable to stay still for six minutes, you are not eligible for a DEXA scan. Otherwise, a baseline scan is worthwhile for adults at any fitness level.

Are there any other restrictions?

Do not consume calcium supplements for 24 hours before your scan, and wait seven days after having a CT with contrast.

Get your baseline
Start with one scan. Track the change.

Getting a baseline scan and regular follow-ups gives you a clear picture of how your body is changing as you get older. We use data-driven recommendations to help you live longer and function better as you age.
