The Osteoporosis Service provides Dual-Energy X-ray Absorptiometry (DEXA) scanning, used to measure bone density, for men and women over 65 who have risk factors or a diagnosis of Osteopenia or Osteoporosis.
What is the purpose of a DEXA scan?
- A DEXA scan is a special type of X-ray that measures bone mineral density (BMD). DEXA stands for "dual energy X-ray absorptiometry". This type of scan may also be called: a DXA scan or a bone density scan and is a means of measuring bone mineral density (BMD). A DEXA scan is typically used to diagnose and monitor osteoporosis, a condition that weakens bones and makes them more likely to break.
- A DEXA scan is more effective than normal X-rays in identifying low bone mineral density.
Are DEXAs safe?
- As well as being quick and painless, a DEXA scan is more effective than normal X-rays in identifying low bone mineral density. The amount of radiation used is extremely small—less than one-tenth the dose of a standard chest x-ray, and less than a day's exposure to natural radiation. X-rays usually have no side effects in the typical diagnostic range for this exam.
DEXA scan procedure
