Radiofrequency Echographic Multispectrometry (REMS) is a New Method of Densitometry (review)

The purpose of the study. To familiarize medical professionals with the possibilities of the new method of densitometry REMS used in the diagnosis of osteoporosis and risk assessment of low-energy fractures.

Materials and methods. The search and selection of publications was carried out on the basis of PubMed, eLibrary, and official websites of international and national medical organizations from 2004 to 2025.

Results.Theliteraturereviewpresentsdataonradiofrequencyechographicmultispectrometry, a new promising ultrasound method used to evaluate quantitative parameters of bone tissue in the lumbar vertebrae and proximal femoral bones, and to determine the risk of fractures. Studies conducted in a number of countries have demonstrated a high degree of consistency between the results obtained using radiofrequency echographic multispectrometry and dual-energy X-ray absorptiometry, which gave reason to recommend a new technique for clinical use in patients with osteoporosis and low bone mass. The authors of the review analyze the practical results, advantages, and unresolved issues of using the new densitometry method.

Conclusions. Radiofrequency echographic multispectrometry is a promising new highly effective method of densitometry, necessary for wider implementation in the diagnosis of osteoporosis and risk assessment of low-energy fractures. At the same time, the comparatively limited application experience requires continued research aimed at studying its advantages and disadvantages in comparison with dual-energy X-ray absorptiometry.
