【 摘 要 】

References(17)The aim of this study was to assess the measurement of bone mineral density (BMD) byquantitative computed tomography (QCT), comparing the relationships of BMD between QCT anddual-energy X-ray absorptiometry (DXA) and between QCT and radiographic absorptiometry(RA) in the metacarpal bone of Holstein dairy cows (n=27). A significant positivecorrelation was found between QCT and DXA measurements (r=0.70,P<0.01), and a significant correlation was found between QCT and RAmeasurements (r=0.50, P<0.01). We conclude that QCTprovides quantitative evaluation of BMD in dairy cows, because BMD measured by QCT showedpositive correlations with BMD measured by the two conventional methods: DXA and RA.
