Understanding Bone Density (DEXA) Scan
A Bone Density Scan, also known as a DEXA (Dual-Energy X-ray Absorptiometry) scan, is a quick and painless imaging test used to measure bone mineral density (BMD). This diagnostic tool helps assess your risk of fractures and conditions like osteoporosis. It's a standard part of preventative care for older adults or those with bone health concerns.
What is a Bone Density (DEXA) Scan?
A DEXA scan uses low-dose X-rays to create images of your bones—usually focusing on the hips, spine, and sometimes the wrist. The scan calculates the density of calcium and other minerals in your bones to determine how strong they are. It is the gold standard for diagnosing osteopenia (low bone mass) and osteoporosis.
The procedure is non-invasive, typically lasts about 10 to 20 minutes, and does not require any injections or incisions.
What to Expect from a Bone Density (DEXA) Scan Service
When you attend a Bone Density (DEXA) Scan service, here’s what you can expect:
A brief medical history review and explanation of the scan
You’ll lie flat on a padded table while a scanning arm passes over your body
The scan is painless and requires no recovery time
Your results are reviewed by a radiologist and sent to your referring doctor
You'll receive a T-score and Z-score that indicate your bone health status
There’s no special preparation needed, but you may be asked to avoid calcium supplements on the day of the scan.

Types of Bone Density (DEXA) Scan Services
DEXA scanning may vary slightly based on the diagnostic need:
Central DEXA Scan: Measures bone density in hips and spine—most accurate
Peripheral DEXA Scan: Targets wrist, heel, or finger—used for screening or mobile services
Whole-body DEXA: Less common, but used in some cases to assess total body composition
All scan types use low radiation levels and are safe for routine use.
The Risks Associated with Bone Density (DEXA) Scan
Bone Density (DEXA) Scans are very safe. Risks are minimal, but may include:
Low radiation exposure: Significantly lower than standard X-rays
Pregnancy concern: Not recommended for pregnant individuals unless medically necessary
