March-June 2010 I hospitals and N of 22 patients in the hospital by DXA and QCT BMD measured at the same object were compared, statistical methods SPSS for Windows program (version 12.0) using the frequency analysis and t-test with a bone age, height, weight, the correlation analysis results were as follows. The distribution of study subjects 19 cases were male and 3 female patients, total 22 patients, 37 years of age ranged from 28 years of age. The mean age of 32.14 years old, and their average height is 170.59 cm, with the average weight was 69.41 kg. In addition to DXA and QCT of how the L2-L4 BMD in level average correlation coefficient was 0.378 with a significant quantitative correlation. Analysis by age rather than the QCT method to DXA showed that 10.8% more valuable, than height level analysis to DXA, QCT method showed 3.4 percent more useful, weight level analysis to DXA is more useful than the 1.2% QCT method was. More results from this study to measure bone density in the DXA method is useful in the age and height and weight by some in the QCT method proved to be useful. Therefore, bone mineral density in patients’ age, height, weight, depending on the selection of accurate measurement is considered to be considered.
