DEXA Scan – Bone Density Test

Most people don't realise their bones are weakening until a fracture happens. A DEXA scan changes that — it is a quick, painless test that measures your bone density before problems arise, giving you and your doctor the information needed to act early and protect your health.

At Scans World, we offer DEXA scanning (Dual-Energy X-ray Absorptiometry) — the gold standard test for diagnosing osteoporosis and assessing fracture risk at our Aminjikarai, Nandanam and Nanganallur centres. The procedure takes just 15 to 20 minutes, uses an extremely low dose of radiation and requires no injection or special preparation. Results are ready the same day.

Why Choose Scans World for Your DEXA Scan in Chennai

What is a DEXA Scan?

DEXA stands for Dual-Energy X-ray Absorptiometry. It uses two low-energy X-ray beams to measure the density of minerals, primarily calcium in your bones. The denser your bones, the stronger they are. The result is expressed as a T-score, which tells you how your bone density compares to that of a healthy young adult.

The scan focuses primarily on the hip and lumbar spine, the two areas most prone to fractures in people with osteoporosis. It is painless, takes only 15–20 minutes and is considered the most accurate and reliable bone density test available today.

T-SCORE GUIDE:

Who should get a DEXA Scan?

• Women above 45 - especially post-menopausal women
• Men above 60
• Long-term steroid users (3+ months)
• People with a history of fractures
• Family history of osteoporosis
• Low body weight
• Smokers and heavy drinkers
• Monitoring bone health treatment effectiveness

What conditions does a DEXA scan detect?

• Osteoporosis – extreme loss of bone density with high fracture risk
• Osteopenia – early bone thinning before osteoporosis develops
• Risk of vertebral fractures, particularly in the lower back
• Hip fracture risk assessment – for older adults
• Secondary osteoporosis – from steroid use, thyroid problems or malabsorption
• Monitoring treatment response – tracking improvement after bone health medication
• Body composition analysis - ratio of fat mass to lean mass

What to expect during your DEXA scan

A DEXA scan is one of the easiest and most comfortable imaging procedures you will ever have. You lie on a padded table, fully clothed, while a slim scanning arm moves slowly over your body — typically focusing on the lower spine and hip. There is no enclosed tunnel, no loud noise and absolutely no discomfort.

The entire procedure takes just 15 to 20 minutes. You can go about your normal day immediately after. Our radiologist will provide a detailed report including your T-score, Z-score and fracture risk assessment — typically ready the same day.
