THE USE OF COMPUTER TECHNOLOGY IN STANDARDIZATION OF THE PARAMETERS OF X-RAY DENSITOMETRY
Abstract and keywords
Abstract (English):
Currently, the radiation techniques are dominant in the diagnosis of osteoporosis, among them the dual-energy X-ray absorptiometry (DXA) is the leading. This method is based on the determination of bone mineral density. The article describes a computerized system Standart LS (Russia), which standardizes the parameters of bone mineral density, depending on the type of densitometry equipment and evaluates the results of X-ray densitometry taking into account a regional perspective. The developed program and population database of parameters of bone mineral density were the results of retrospective analysis of the dual-energy X-ray absorptiometry in 1504 women living in Kemerovo region. The dual-energy X-ray absorptiometry was performed with a bone densitometer Lunar-DPX-NT (GE Healthcare, UK). Initially, the bone mineral density of the first-fourth lumbar vertebrae was studied; then, the standardization of other parameters of densitometric systems was carried out (Hologic, Norland). The algorithm of the computer program consists of three phases: the introduction of parameters of bone mineral density, the standardization and the processing according to a type of densitometer and an age of a subject. After data processing, the values of Z-criteria are given out according to the recommendations of the International Society for Clinical Densitometry. The developed computerized system will contribute to a more accurate assessment of bone mineral density in the women, taking into account regional differences.

Keywords:
bone mineral density, dual-energy X-ray absorptiometry (DXA), computerized system of standardization and analysis.
