HIGHLIGHT:<\/p>\n

REMS performed similarly to DXA in assessing trabecular integrity using TBS. Additionally, no statistically significant difference was observed in fracture risk assessment by FRAX based on NOGG recommendations.<\/strong><\/em><\/p>\n

The recent study\u00a0\u201cDoes Radiofrequency Echographic Multi-Spectrometry (REMS) perform similarly to Dual-energy X-ray Absorptiometry (DXA) in terms of Trabecular Bone Score (TBS) and FRAX? \u201c<\/strong>\u00a0published in Archives of Endocrinology and Metabolism, the official journal of the Brazilian Society of Endocrinology and Metabolism, by the Professor Lazzaretti Castro\u2019s research team, evaluated whether bone assessment by REMS was influenced by trabecular bone integrity by comparing it DXA and TBS. Additionally, the study aimed to determine if comparing fracture risk using FRAX and the National Osteoporosis Guideline Group (NOGG) using the T-score from each method would lead to differences in a Brazilian female population, including individuals from diverse ethnic backgrounds and clinical conditions.<\/p>\n

The obtained results showed that\u00a0REMS<\/strong>\u00a0performed similarly to DXA in assessing trabecular integrity using TBS. Half of the exams classified as normal by DXA but osteopenic by\u00a0REMS<\/strong>\u00a0were classified as partially degraded or degrad\u00aded by TBS, suggesting that REMS might be more asser\u00adtive in identifying bone microarchitecture.\u201dThe particular importance of this study lies in showing the similarities between REMS and DXA and in identifying the discordant cases where REMS may have detected the impaired bone quality shown by TBS\u201d the researchers stated.<\/p>\n

Additionally, the FRAX risk probabilities calculated using REMS or DXA did not show statistical differences, which may be of interest for clinical practice. The intervention thresholds for osteoporosis treat\u00adment defined by the FRAX-NOGG strategy using the femoral neck T-score obtained by REMS were not dif\u00adferent from those obtained using the DXA femoral neck T-score. Previously, the authors have reported the high accura\u00adcy of REMS for diagnosing DXA-defined osteoporosis in this same sample of women. These findings suggest that REMS performs similarly to DXA and may become a surrogate method for diagnos\u00ading osteoporosis and fracture risk stratification using FRAX.<\/p>\n

Finally,\u00a0REMS<\/strong>\u00a0device is less expensive than a DXA densitometer, but there is still room for price reduction as it becomes more commercialized. In addition, it is portable, meaning it can be transported to different diagnostic centers covering larger geographic regions, increasing the population\u2019s access to the exam and, consequently, to the diagnosis of osteoporosis. It is simpler to perform than DXA and as it does not contain ionizing radiation, there are no restrictions regarding radiological protection or technicians\u2019 exposure.<\/p>\n

In conclusion, the obtained results suggest that REMS could offer significant advantages in osteoporosis diagnosis, combining effectiveness and practicality and its ability to detect microarchitectural degradation allows for a more precise assessment of fracture risk.<\/strong><\/p>\n
