What is a REMS bone density scan?
REMS (radiofrequency echographic multi-spectrometry) is an ultrasound-based way to measure bone density at the hip and spine without ionising radiation. It gives a T-score and Z-score, the measures used to identify osteopenia and osteoporosis, and an estimate of fracture risk.
REMS or DEXA: what is the difference?
DEXA is the long-established X-ray test used by the NHS to diagnose osteoporosis. REMS measures the same sites using ultrasound, with no radiation, and has been shown to agree well with DEXA in clinical studies. Some doctors and treatment pathways still require a DEXA, and your specialist will tell you if you need one.
Is REMS a diagnostic test or a screening tool?
REMS gives a bone density result with T-scores used for diagnosis and is CE-marked for that purpose. In practice, many people use it to check their bone health or monitor changes; if treatment is being considered, your GP or specialist may also request a DEXA scan.
Who should consider a bone density scan?
A bone density scan is worth considering if you:
- Are a woman past the menopause, especially an early menopause
- Have broken a bone after a minor fall
- Have taken steroid tablets for three months or more
- Have a parent who broke a hip
- Have a low body weight, smoke, or have conditions affecting bone, such as rheumatoid arthritis
What is osteoporosis?
Osteoporosis is a condition where bones become thinner and more fragile, so they break more easily, often after a minor fall. It has no symptoms until a fracture happens, which is why measuring bone density matters for people at risk.
What do the T-score and Z-score mean?
The T-score compares your bone density with a healthy young adult:
- -1.0 or above: normal
- Between -1.0 and -2.5: osteopenia (lower than average)
- -2.5 or below: osteoporosis
The Z-score compares you with people of your own age and helps identify other causes of bone loss.
Can a bone density scan show arthritis or fractures?
A bone density scan measures how dense your bones are; it is not designed to diagnose arthritis, fractures or other bone conditions. If you have pain, a suspected fracture or joint problems, an X-ray or another scan is the right test.
Can I get a REMS scan on the NHS?
The NHS uses DEXA scans for bone density, usually after a GP referral based on your fracture risk. REMS is not widely available on the NHS. A private REMS scan lets you check your bone health without radiation, and the report can be shared with your GP.
Is the scan safe? Is there any radiation?
Yes, it is safe, and there is no ionising radiation at all, which makes REMS suitable for repeated monitoring and for anyone who wishes to avoid X-ray exposure.
How often should the scan be repeated?
It depends on your result and risk. With normal bone density, a repeat after several years may be enough; with osteopenia or on treatment, every one to two years is common. Your report suggests an interval.
How can I protect my bones?
Regular weight-bearing and strength exercise, enough calcium and vitamin D, not smoking, limiting alcohol and preventing falls all help. If your bone density is low, your GP may discuss medicines that strengthen bone.
Can men have a bone density scan?
Yes. Men can develop osteoporosis too, particularly with low testosterone, long-term steroid use, heavy drinking or a previous fracture. The scan works the same way.
How long does a REMS scan take?
Around twenty to thirty minutes, including a short conversation about your risk factors, the scan of the spine and hip, and time to explain your results.
How much does a REMS bone density scan cost?
At Harley Street Ultrasound a private REMS bone density scan costs £250, all fees inclusive: the scan of the spine and hip, your T-score and Z-score, the specialist’s time and your written report.
What if you find something?
Your specialist tells you in the room, in plain English, and explains exactly what it means. You will never be sent home to wait for a letter. Most findings are benign and need nothing more than a sensible review date.
Anything that does need attention gets a clear, objective recommendation in your report: monitor, test further, or refer. Follow-up tests can usually be arranged at 99 Harley Street, often the same week, and those results are also explained to you personally.
Do I need a referral?
No. Harley Street Ultrasound is a private clinic, so you can book a REMS bone density scan in London directly online or by phone. No GP letter, no waiting list, and same-day or next-day appointments are usually available. If you are searching for a REMS bone density scan near me from anywhere in central London, we are at 99 Harley Street, a short walk from Regent’s Park and Oxford Circus stations.
If you are wondering how much a private REMS bone density scan costs, the answer is published before you book: £250, all fees inclusive: the examination, the specialist’s time, your written report and your images. Insured patients should bring a referral or authorisation number if their policy requires one.
How soon will I have the written report?
Usually the same day: a Harley Street REMS bone density scan comes with same-day results as standard, and you will already know the findings, because they are explained to you on screen during the appointment.
The written report is prepared by the specialist team and published to your secure patient portal together with your images, with measurements and a clear recommendation, ready to share with your GP or specialist.
What happens after the scan?
Nothing special: there is no aftercare needed. You can eat, drive and go back to work straight away. Diagnostic ultrasound at these intensities has no confirmed adverse effects, which is why it can be repeated safely for monitoring. If your results suggest a next step, your specialist explains it before you leave.
Can I still use the NHS afterwards?
Yes: completely. Coming to us privately never affects your NHS care. Our job is to get you answers quickly; if anything needs urgent attention, your specialist writes to your NHS GP recommending an urgent appointment, so you re-enter the NHS pathway with a diagnosis already in hand rather than joining the queue from the start.
