DEXA scans
What is the DEXA used for?
A DEXA scan, which stands for Dual-Energy X-ray Absorptiometry, is a specialised imaging technique primarily used to measure bone mineral density. This non-invasive procedure helps assess the strength and health of bones, making it a crucial diagnostic tool for identifying conditions like osteoporosis and assessing fracture risk.

What does a DEXA test show?
A DEXA test offers a comprehensive picture of bone health by measuring bone mineral content and density. The results provide a T-score, which compares an individual’s bone density to that of a young, healthy adult. The T-score helps categorise bone health into three levels: normal, osteopenia (lower than normal bone density), and osteoporosis (severely reduced bone density). The scan’s outcomes aid healthcare professionals in assessing fracture risk and devising suitable treatment strategies.
How much does a DEXA scan cost in the UK?
The cost of a DEXA scan in the UK can vary based on several factors, including the location, healthcare provider, and specific services included. On average, a DEXA scan can range from £100 to £250. Some private clinics may offer packages that include additional services or consultations. It’s advisable to contact healthcare facilities directly or consult with your healthcare provider to obtain accurate and up-to-date cost information.
Why would a doctor order a DEXA scan?
Doctors often recommend DEXA scans for various reasons. Primarily, they’re ordered to evaluate bone health and assess the risk of fractures, especially in individuals with risk factors like advanced age, postmenopausal women, and those with certain medical conditions. DEXA Scan and Bone Health DEXA scans are instrumental in diagnosing osteoporosis and osteopenia, guiding treatment decisions, and monitoring bone health over time. DEXA scans are also commonly being used to assess body composition. See our other article for more information DEXA Scan and Body Composition.
Where can I get a DEXA scan?
Scans are available in a variety of healthcare settings, including hospitals, specialised imaging centres, and private clinics. Many major medical centres offer DEXA scan services as part of their radiology departments. Private clinics may also provide DEXA scans as a standalone service.
