Introduction: Radiofrequncy echographic multispectrometry (REMS) is radiation-free innovative technology for assessing bone density and quality of the spine and hip through revolutionary approach. REMS has demonstrated diagnostic accuracy comparable to the gold standard dual-energy X-ray absorptiometry (DXA). In contrast to DXA, REMS involves minimal human intervention during the scan, which could contribute to reduced rates of discordance between hip and spine T-scores. The aim of this study was to identify the prevalence of discordance between hip and spine T-Scores assessed with REMS.

Methods: The results from 180 participants who underwent REMS scans of both the hip and spine were evaluated. T-score differences of less than one standard deviation (SD) were categorized as an “absence of significant discordance”, differences between one and two SD were classified as “minor discordance,” and differences exceeding two SD were labeled as “major discordance”.

Results: Among the 180 participants, minor discordance was observed in only six cases (3.3%), with no instances of major discordance. In four of the six cases with minor discordance (2.2% of the total), the T-score differences between the hip and spine did not affect the final diagnosis. However, in the remaining two cases (1.1% of the total), the T-score differences influenced the final diagnosis, resulting in a classification of osteopenia for the spine and normal bone density for the hip.

Discussion: The findings of this study demonstrate a low prevalence of discordance between hip and spine T-scores assessed with REMS, with minor discordance observed in only 3.3% of cases and no instances of major discordance. Moreover, in the majority of cases with minor discordance, the differences in T-scores did not affect the final diagnosis. These results highlight the reliability of REMS as a diagnostic tool for assessing bone density and quality, with minimal impact from discordance, further supporting its potential as an alternative to DXA.
