Abstract

The paper summarises the present knowledge of the new bone densitometry method called radiofrequency echographic multi-spectrometry (REMS). This ultrasound-based approach enables the evaluation of bone mineral density (BMD) in the hip and the lumbar spine. During REMS densitometry, a fully automatic algorithm performs a series of spectral and statistical analyses involving both echographic images and corresponding “raw” (unfiltered) radiofrequency signals. This provides the identification of the region of interest (ROI) and the calculation of standard densitometric parameters: BMD, T-score and Z-score. Nondiagnostic scans and artifacts are automatically excluded by the algorithm, reducing the risk of false results. A recently published multi-center study has demonstrated high diagnostic sensitivity, specificity and accuracy of this innovative method in the diagnosis of osteoporosis. To the authors’ best knowledge, this is the first Polish paper on REMS densitometry.
