What do you mean by DEXA?
A DEXA scan is a type of medical imaging test. It uses very low levels of x-rays to measure how dense your bones are. 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.
What is DEXA in nutrition?
DEXA, or Duel-Energy X-ray Absorptiometry, measures both bone mineral density (BMD) and body composition (fat and lean mass %). It is considered the gold standard for body composition measurements. Track fat loss and muscle gain progress in specific areas of the body.
How DEXA scan is done?
During the scan, a large scanning arm will be passed over your body to measure bone density in the centre of the skeleton. As the scanning arm is moved slowly over your body, a narrow beam of low-dose X-rays will be passed through the part of your body being examined.
How does a DEXA scan work?
DXA works by sending two low-dose X-rays which are absorbed differently by bones and soft tissues. The density profiles from these X-rays are used to calculate bone mineral density. The lower the density, the greater the risk of fracture. DXA is painless and takes about 10 minutes.
What was DEXA originally used for?
Dual-energy X-ray absorptiometry (DXA) is a method developed originally for the measurement of bone density and mass.

Does a DEXA scan produce an image?
Bone densitometry, also called dual-energy x-ray absorptiometry, DEXA or DXA, uses a very small dose of ionizing radiation to produce pictures of the inside of the body (usually the lower (or lumbar) spine and hips) to measure bone loss.
How do you read a DEXA scan?
A T-score of 0 means your bone density is equal to that of a healthy young adult. The lower the T-score, the lower the bone density: A score of –1.0 to +1.0 means you have normal bone density. A score between –1.0 to –2.5 means you have low bone density (osteopenia).
