How do you read a DXA scan?
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.
What can DXA be used to diagnose?
A bone density scan uses low dose X-rays to see how dense (or strong) your bones are. You may also hear it called a DEXA scan. Bone density scans are often used to diagnose or assess your risk of osteoporosis, a health condition that weakens bones and makes them more likely to break.
How do you interpret a Z score on a DEXA scan?
The Z score gives an indication of bone density compared to a healthy person of the same age and gender. A Z score of -2 in a 50 year old would indicate a 20% greater loss of bone density compared to what the expected ‘normal’ bone loss for a 50 year old would be.
What does the DXA measure?
A DEXA scan is an imaging test that measures bone density (strength). DEXA scan results can provide helpful details about your risk for osteoporosis (bone loss) and fractures (bone breaks). This test can also measure your body composition, such as body fat and muscle mass.
Can you wear a bra for a DEXA scan?
Preparing for your DEXA (Bone Density) Do not wear a bra with an underwire. Stop taking your calcium supplement 48 hours before your scan. Tell the technician if you had any back or hip surgery.
Do I have to undress for a bone density scan?
In most cases, you do not need to undress. This scan is the best test to predict your risk for fractures, especially of the hip. Peripheral DEXA (p-DEXA) — These smaller machines measure the bone density in your wrist, fingers, leg, or heel.
What do the results of a DXA scan show?
DXA Scan Results. For the results of your scan, you’ll get a T-score. It shows how much higher or lower your bone density is than that of a healthy 30-year-old, the age when bones are at their strongest. The lower your score, the weaker your bones are: Sometimes doctors will give you another DXA scan result — a Z score.
What is bone density scan ( DEXA, DXA )?
What is a Bone Density Scan (DEXA,DXA)? Bone density scanning, also called dual-energy x-ray absorptiometry (DXA) or bone densitometry, is an enhanced form of x-ray technology that is used to measure bone loss. DXA is today’s established standard for measuring bone mineral density (BMD).
Where can I get a DXA scan on my arm?
DXA scanning focuses on two main areas — the hip and the spine. If you can’t test those, you can get a DXA scan on your forearm. A DXA scanner is a machine that produces two X-ray beams.
Where are the Central devices used for DXA?
Most of the devices used for DXA are central devices, which are used to measure bone density in the hip and spine. They are usually located in hospitals and medical offices. Central devices have a large, flat table and an “arm” suspended overhead.
