ON THE UNIFICATION OF BONE DENSITOMETRY AND INTERPRETATION OF ITS RESULTS

Abstract

The paper gives data on the importance of osteoporosis, existing approaches to its diagnosis, the specific features of a dual-energy X- ray absorption procedure to measure bone density, the determination of main densitometric indicators, such as a T-score and a Z-score, as well as their interpretation, by predicting the probability of bone fractures. It shows the need for population-based studies in Russia to set up a normative bone mineral density base with regard to age- and gender-related differences and other factors influencing the bone structure. The concept of a threshold for intervention is discussed, which determines diagnostic and therapeutic tactics depending on what risk group a patient belongs to. It is noted that the surveys conducted among radiologists have indicated that most specialists are poorly aware of the problem of osteoporosis, its diagnosis, prevention, and treatment.
