Bone Density Scan For Osteoporosis
A DEXA scan is a special type of X-ray that measures bone mineral density (BMD). The initials DEXA stands for ‘Dual Energy X-ray Absorptiometry’. This is also referred to as a bone density scan or bone densitometry scan.
These are used to diagnose osteoporosis (this is when the bones become weak and fragile, and are more likely to break). These machines can also be used to assess the risk of Osteoporosis developing in women aged 50 and in men over 60.
DEXA tests are quick and painless and more effective than normal X-rays in identifying low bone mineral density.
Who is at risk of Osteoporosis?
- Over 50 years of age
- Under 50 if you are a smoker
- Under 50 and had a previous fracture
- Post-menopausal women are particularly at risk
DEXA scans use a much lower level of radiation than standard X-ray examinations, this means that the radiographer can stay in the scanning room with you during the scan.
