REMS vs DXA for Osteoporosis Diagnosis and Fracture Risk Prediction

This prospective, observational, comparative diagnostic study will evaluate the performance of Radiofrequency Echographic Multi Spectrometry (REMS) for the diagnosis of osteoporosis and prediction of fragility fracture risk in a U.S. population, using dual-energy X-ray absorptiometry (DXA) as the reference standard. Approximately 250 male and female participants aged 30-90 years who are undergoing evaluation for bone health will be enrolled at Rheumatology Associates of Delmarva. Participants will have clinically obtained DXA results and undergo REMS assessment of the lumbar spine and proximal femur. Diagnostic performance, including sensitivity, specificity, predictive values, and concordance between REMS and DXA, will be evaluated. Participants will also be followed by telephone at 6 and 12 months to identify incident non-traumatic fragility fractures and assess the ability of REMS and DXA to predict fracture risk.

Automated Bone Age Estimation From Noncontrast Abdominal CT Using Deep Learning

This study is a retrospective analysis that uses abdominal CT scans, which were originally taken for other medical reasons, to estimate bone age. By applying advanced deep learning methods, the investigators aim to develop a tool that can evaluate bone health and detect early signs of osteoporosis without requiring additional scans or radiation. This approach may help doctors better understand bone aging, improve screening for bone weakness, and provide patients with more personalized information about their bone health.

Bone Evaluation by Ultrasound Radiofrequency Echographic Multi Spectrometry (REMS) vs Dual X-ray Absorptiometry (DXA)

Bone Density Evaluation by means of the Ultrasound Technology Named Radiofrequency Echographic Multi Spectrometry (REMS) in Comparison With DXA Technique. Clinical Center involved in the study:IRCCS Orthopedic institute Galeazzi - Sant'Ambrogio The clinical study will evaluate the intra- and inter-operator repeatability of the REMS,(Radiofrequency Echographic Multi Spectrometry) ultrasound diagnostic technology implemented in the EchoStation device (Echolight Spa, Lecce) and the diagnostic accuracy in comparison with DXA (used as standard reference).
