NHS DEXA Scan Expansion: Faster Diagnosis & Fracture Prevention

The National Health Service (NHS) in England is bolstering its capacity to diagnose osteoporosis and other bone conditions with the rollout of 20 new DEXA scanners, aiming to speed up diagnosis and reduce the incidence of fragility fractures. The initiative, announced on March 1, 2026, will see both replacement scanners for aging equipment and additional units to increase scanning availability across the country.

What are DEXA Scans and Why are They Important?

DEXA, which stands for dual-energy X-ray absorptiometry, is a type of low-dose X-ray used to measure bone mineral density. As the NHS explains, these scans are crucial for diagnosing osteoporosis – a condition where bones become weak and brittle – and assessing an individual’s risk of fractures. Unlike standard X-rays, DEXA scans are specifically designed to identify low bone density, even before a fracture occurs. This early detection is vital, as treatment can significantly reduce the risk of debilitating breaks.

Osteoporosis doesn’t always present with obvious symptoms, making routine screening particularly important for those at higher risk. Risk factors include being over 50, having a family history of the condition, smoking, and previous broken bones. Women are disproportionately affected, particularly after menopause due to the decline in estrogen levels, which plays a key role in maintaining bone density.

Expanding Capacity: Where Will the New Scanners Be Located?

The 20 new scanners are being distributed across England, with some replacing outdated models and others adding to existing capacity. Specifically, the East of England will receive two new scanners: one at Hinchingbrooke Hospital (North West Anglia NHS Foundation Trust) as a replacement for a 15-year-old model, and another at St Albans City Hospital (West Hertfordshire Teaching Hospitals) to increase scanning capacity. Hinchingbrooke Hospital carried out 6,304 DEXA scans last year alone, highlighting the existing demand. Further details on the locations of the remaining 18 scanners are available from the Department of Health and Social Care.

The Impact of Faster Diagnosis

The investment in new DEXA scanners is expected to have a significant impact on patient care. Shorter scan times and increased appointment availability will mean faster diagnosis for those suspected of having osteoporosis. This, in turn, allows for earlier access to treatments designed to reduce fracture risk. Tom Lidgett, Operational Lead Radiographer at North West Anglia NHS Foundation Trust, emphasized that the new scanner at Hinchingbrooke represents “a significant step forward for our local services, as we look towards prevention with shorter scan times enabling faster diagnosis.”

Dr. Niall Keenan, Divisional Director for Medicine at West Hertfordshire Teaching Hospitals NHS Trust, underscored the importance of this service, noting that osteoporosis is “extremely common” and can have “devastating consequences for independent living” in older people. He added that the additional scanner will “change the lives of many people in Hertfordshire and the wider region for years to reach.”

Beyond New Scanners: A Broader Trend in DEXA Scan Availability

This latest investment builds on previous efforts to improve access to DEXA scans. In 2025, over 16,000 more DEXA scans were performed compared to 2024, demonstrating a growing commitment to proactive bone health management. The current rollout of 20 scanners represents a further expansion of this initiative. Health and Social Care Secretary Wes Streeting stated that the goal is to prevent “painful, preventable fractures” by diagnosing osteoporosis earlier, particularly among women.

Understanding Fracture Risk and the Role of DEXA Scans

It’s important to understand that a DEXA scan is just one piece of the puzzle when it comes to assessing fracture risk. The results of the scan are typically used in conjunction with a fracture risk assessment, which takes into account a variety of factors, including age, gender, ethnicity, medical history, and lifestyle. This comprehensive assessment helps clinicians determine an individual’s overall risk and whether treatment is necessary.

The scan results are often presented as a T-score, which compares a patient’s bone density to that of a healthy young adult. A T-score of -1.0 or above is considered normal, although a T-score between -1.0 and -2.5 indicates osteopenia (low bone density), and a T-score of -2.5 or below indicates osteoporosis. However, treatment decisions are not solely based on T-scores; the overall fracture risk assessment is crucial.

What Comes Next: Monitoring and Future Developments

The NHS will continue to monitor the impact of these new scanners on waiting times and fracture rates. Ongoing surveillance will help identify any areas where further improvements are needed. The Department of Health and Social Care has not yet announced any further plans for expanding DEXA scanning capacity, but the success of this current initiative will likely inform future investment decisions. Patients concerned about their bone health should discuss their risk factors with their GP and ask about the possibility of a bone density scan if appropriate.
