Abstract:
OBJECTIVES: The purpose of this study was to compare total body fat mass, lean mass, and bone mineral content in addition to regional fat measured by the same model of equipment installed in different places, and to determine the extent of agreement. MATERIALS AND METHODS: Twenty seven healthy volunteers aged 20 years and over received two consecutive total body scans using the same dual-energy X-ray absorptiometry model of installed in different places. All scans were conducted on the same day. RESULTS: Relatively good agreements were shown in fat mass, the percent of tissue fat, android fat, and gynoid fat. However, there were two outliers each in lean mass and bone mineral content based on the limits of agreement. CONCLUSIONS: These results indicate the need for cross-calibration even with the same model of equipment.
