REMS Scan – Frequently Asked Questions
REMS (Radiofrequency Echographic Multi-Spectrometry) is a radiation-free ultrasound technique that assesses bone status and estimates fracture risk using signals from the hip and/or spine.
Both assess bone health, but DEXA uses low-dose X-rays, whereas REMS uses ultrasound (no ionising radiation). Your clinician may advise one or both depending on your situation.
No—REMS is ultrasound-based and does not involve ionising radiation, making it an extremely safe imaging method.
People with risk factors that may affect bone health (e.g., menopause, family history of fractures, long-term steroids, low BMI, certain medical conditions) or anyone who wants to understand their current bone health.
Typically 15–20 minutes for the scan itself; we allow 60 minutes in total for the full consultation.
No special preparation. Wear comfortable clothing that allows easy access to the hip and abdomen. It is best to avoid eating a heavy meal within 3 hours of the scan as this can generate bowel gas that can make scanning the spine more challenging.
No—REMS uses a handheld ultrasound probe on the skin surface with gel. You may feel gentle pressure but it shouldn’t be painful.
REMS uses ultrasound (not X-rays) which is safe in pregnancy.
We cannot scan hips if they have been replaced. We can usually scan the spine even if metalwork has been inserted. We scan the lumbar vertebrae from L1–L4.
Both hips and the lumbar spine, accessed through the abdomen, are assessed.
Your results will be discussed with you directly after the scan and we will provide you with a report for your records and ongoing care plan.
Your clinical background is considered when interpreting results. Please tell us about all medicines and supplements, especially steroids, thyroid meds, and bone-active therapies.
REMS is non-invasive and uses ultrasound. Adverse effects are uncommon. Let us know if you have skin sensitivities to gels.
REMS provides a detailed bone health assessment, including bone mineral density and an estimated fracture risk.
These results can indicate whether your bone health is in the normal, osteopenic (low bone mass), or osteoporotic range.
However, the formal diagnosis of osteoporosis is made by a clinician, who will also consider your full medical history, risk factors, and any additional investigations before recommending treatment or management options.
