What is Dexa Scan?

what is dexa scan

With the evolution of technology over the years, it's no surprise that there will always be a way to be able to prevent things that are about to happen. Just like with osteoporosis, most of us accepted it as an inevitable part of aging. While it affects most of the women over the age of 50, what's even scarier is that we don't really know until it's there. Once your bones become fragile that's caused by a decrease in the density of bones, a person is exposed to developing fractures and signs and symptoms of back pain.

So what can we do in order to identify osteoporosis? That's where DEXA SCAN comes in. A DEXA (Dual-Energy X-ray Absorptiometry) Scan provides accurate measures of body fat, muscle, and bone composition, and lets you track changes in body composition over time. It uses x-ray technology to determine the distribution of lean muscle, fat, water and bone in your body. Unlike any other body composition measuring tool, DEXA results are highly accurate and highly reproducible.

body composition

DEXA Scan gives you the most precise information about your body fat, muscle, and bone composition, and lets you track changes in body composition over time. Fitness enthusiasts, athletes, and dieter often use body composition scans to get a baseline of where they are now and to objectively measure their progress. It also gives you accurate measurements of fat and muscle distributed around your body. See muscle asymmetry that you need to correct to reduce injuries. And track potentially dangerous visceral fat around your vital organs. 

Dexa helps you monitor your weight loss progress. An initial baseline scan lets you see exactly where you are when you start and then track how much body fat they are actually losing, and how much muscle you are gaining. 

Getting a baseline measurement of fat, muscle, and bone lets you see where you are and track changes over time. We often lose muscle and bone mass as we age, particularly in the core, and legs. This puts us at greater risk of injury. Having a baseline measurement and tracking changes over time helps identify concerning trends and lets you take preventative action early.

dea scan bone density

A Bone Densitometry test is used to measure how strong your bones are. It is commonly used to identify osteoporosis, a condition that causes a decrease in the density of bones resulting in fragility and to determine a person’s risk for developing fractures.

When should you be able to take the DEXA BONE DENSITY SCAN
  • Are female and older than 65
  • Are female, menopausal or post-menopausal and:
    • Under the age of 45
    • Under the age of 65 with other risk factors
    • Not taking estrogen
    • Over 5 feet 7 inches tall
    • Weigh less than 125 pounds
  • Are male and older than 70
  • Are male and have clinical conditions associated with bone loss
  • Have broken a bone over the age of 50
  • Have lost more than an inch of height
  • Have unexplained back pain
  • Have a personal or family history of:
    • Hip Fracture
    • Smoking
    • Osteoporosis
  • Use medications that are known to cause bone loss (including corticosteroids such as Prednisone, various anti-seizure medications such as Dilantin and certain barbiturates or high-dose thyroid replacement drugs)
  • Have Type I Diabetes, Liver Disease or Kidney Disease
  • High bone turnover (shows up in the form of excessive collagen in urine samples)
  • Thyroid condition, such as Hyperthyroidism.
  • Parathyroid condition, such as Hyperparathyroidism.
  • Experienced a fracture after only mild trauma.
  • X-ray evidence of vertebral fracture or other signs of osteoporosis
  • When you are a heavy drinker
When it is not a good idea to get a scan
  • Under 18 years of age
  • Pregnancy
  • DEXA scan within the past 8 weeks
  • A total of 4 DEXA scans in the past year
  • Unable to maintain a motionless position for 7 minutes whilst being scanned

The total scan takes about 7 minutes, where you’ll be lying flat on the scanning bed. The DEXA is the ‘gold standard’ body composition testing. It has the greatest precision and shorter scan times.

A Bone Densitometry test is used to measure how strong your bones are. It is commonly used to identify osteoporosis, a condition that causes a decrease in the density of bones resulting in fragility and to determine a person’s risk for developing fractures. The risk for developing fracture is determined by age, weight and family/personal history. Talk to your doctor before scheduling a bone density scan.

DEXA is today’s established standard for measuring bone mineral density (BMD) and is most often performed on the spine, hips or forearm.

STEP 1
Talk to your doctor about your eligibility for Bone Density Testing

STEP 2
Your doctor will recommend a nearby Dexa Scan provider that is covered by your health insurance.

STEP 3
Schedule an appointment for the scan and an additional appointment with your doctor to discuss the results.

STEP 4
Prepare! Do not take calcium supplements for at least 24 hours before the exam and avoid wearing clothes with metal zippers or hooks.

STEP 5
Lay flat on the scanning bed for roughly 10 to 20 minutes.

STEP 6
Discuss your results with your health care provider.

What type of result should you expect?

T score: This number shows your Bone Mineral Density compared to young adults of the same gender in peak health.
  • -1 and above: this is considered a normal score
  • between -1 and -2.5: this is classified as osteopenia (low bone mass)
  • below -2.5: this is classified as osteoporosis (extremely low bone mass)
Z score: This number shows your Bone Mineral Density compared to other people in your age group of the same size and gender. If this score is more than 2 standard deviations above or below average, it may indicate a need for further medical tests.

  2. I've had bone density problems in the past and would love to get a dexa to check that everything is fine now x
