Radiation-free ultrasound-based bone density and quality assessment with same-day results, T-score, fragility score, and 5-year fracture risk evaluation.
Answer: REMS bone assessment is a screening tool for adults concerned about bone health and is not a replacement for diagnostic imaging ordered by a physician. Individuals currently under active treatment for osteoporosis should discuss REMS results with their treating physician. REMS results do not replace DEXA scans required for insurance-mandated treatment monitoring.

Answer: REMS (Radiofrequency Echographic Multi Spectrometry) measures both bone density and bone quality using zero-radiation ultrasound. DEXA measures only bone mineral density using low-dose X-ray. REMS provides a Fragility Score and 5-year fracture risk prediction that DEXA does not offer, with same-day results at our Half Moon Bay location.

FAQ
Answer: Common questions about REMS bone health assessments at our Half Moon Bay location include appointment length (~20 minutes), insurance (HSA/FSA accepted), referral requirements (none needed), and what to wear (comfortable, loose-fitting clothing).
REMS (Radiofrequency Echographic Multi Spectrometry) is an FDA-cleared, radiation-free ultrasound technology that measures both bone mineral density and bone quality. Unlike DEXA scans, REMS uses no ionizing radiation and can be performed in approximately 20 minutes with same-day results.
DEXA scans use X-ray radiation and measure only bone mineral density (BMD). REMS uses ultrasound, involves zero radiation exposure, and measures both BMD and bone quality — providing a more complete picture of bone health. REMS also calculates a Fragility Score and 5-year fracture risk that DEXA does not offer.
