FAQ: What Does Dexa Mean In Orthopedics?

What is the purpose of DEXA?

Bone density scans, also known as DEXA scans, help to work out your risk of breaking a bone. They’re often used to help diagnose bone-related health problems, such as osteoporosis, or to assess the risk of getting them.

How long does a DEXA scan take?

An X-ray detector inside the scanning arm measures the amount of X-rays that have passed through your body. This information will be used to produce an image of the scanned area. The scan usually takes 10 to 20 minutes. You’ll be able to go home after you have had it done.

Can a DEXA scan show a fracture?

A DEXA scan detects weak or brittle bones to help predict the odds of a future fracture and, sometimes, to determine if someone should be taking medication (such as a bisphosphonate) to slow bone loss.

What do my DEXA scan results mean?

DXA Scan Results The lower your score, the weaker your bones are: T-score of -1.0 or above = normal bone density. T-score between -1.0 and -2.5 = low bone density, or osteopenia. T-score of -2.5 or lower = osteoporosis.

At what age do you stop DEXA scans?

The test, called a DEXA scan, is a kind of X-ray. Many people get a bone-density test every few years. The main reason to have the test is to find and treat serious bone loss. But most men, and women under age 65, probably don’t need the test.

Who needs DEXA scan?

Who should get a bone-density scan? For women over 65 and men over 70, DEXA scans are only appropriate for those with moderate risk of fracture or when the results will change the patients care plan. Younger women and men ages 50 to 69 should consider the test if they have risk factors for serious bone loss.

Can you wear a bra for a DEXA scan?

Patient should wear loose, comfortable clothing. Sweat suits and casual attire without zippers, buttons, grommets, metal hooks, or underwire bra.

Can I wear a bra for a bone density test?

Do not wear jewelry, hearing aids, belt buckles, zippers, snaps, or buttons. Females should wear a sports bra. Bras with under wires will need to be removed. It is okay to eat anytime before or after the exam.

Are DEXA scans worth it?

DEXA stands for “dual-energy X-ray absorptiometry.” Medical experts consider DEXA scans to be the most useful, easy, and inexpensive test for helping to diagnose osteoporosis. The test is quick and painless.

What happens if you take calcium before a DEXA scan?

Why can’t I take calcium supplements or multiple vitamins on the day of my DEXA scan prior to my test? If the calcium supplement is not completely dissolved, it will be interpreted by the DEXA instrument as extra bone and may produce an inaccurate reading.

Will DEXA scan show arthritis?

A bone densitometry (density test) helps determine your overall bone mass, along with your risk for fractures. While a bone density test alone can’t determine whether you have arthritis, your doctor may order one if you have inflammatory types of joint disease, as these can be risk factors for bone loss.

How often should you get a DEXA scan?

Don’t routinely repeat dual energy x-ray absorptiometry (DEXA) scans more often than once every two years. Rationale and Comments: Initial screening for osteoporosis should be performed according to National Osteoporosis Foundation (NOF) recommendations.

What happens if your bone density is low?

A person may have low bone mass at any age but not develop osteoporosis. However, if a person has low bone mass and continues to lose bone density, this may lead to osteoporosis. A combination of low bone mass and a risk factor for fracture may increase your risk for broken bones, too.

What should my bone density be for my age?

A T score of -1 to +1 is considered normal bone density. A T score of -1 to -2.5 indicates osteopenia (low bone density). A T score of -2.5 or lower is bone density low enough to be categorized as osteoporosis.

Can I drink milk before a bone density test?

Do NOT eat foods high in calcium for 3-4 hours before your DXA scan. These foods include: milk, cheese, yogurt, and dark green leafy vegetables. Do NOT take calcium supplements, vitamins, or TUMS® on the day of your scan.
