Objective To compare the difference of bone mineral density measurement between lumbar quantitative CT (QCT) and DXA in Tibetans and Han nationality, and to discuss clinic value of QCT and DXA in Tibetan patients. Methods General character information and DXA, QCT reports were collected at Hospital of Chengdu Office of People's Government of Tibetan from December 2018 to September 2019. The imaging diagnosis of these patients was performed by experienced radiologists through lumbar CT images. Normal distribution data were showed as mean and standard deviation. The t test was used for the comparison of independent samples between the groups. Fisher, s exact probability calculation method was used to compare the sample rate between the groups. Results The average DXA 71 value in Tibetan patients was higher than that in Han patients (-0. 19±2. 44 vs. -1. 17士 1.40, P<0. 05). However, there was no significant difference of BMD between Tibetan and Han patients measured with QCT (71. 51 + 24. 10 vs. 75. 31+25. 01 mg/cc). The number of cases of osteoporosis detected with QCT was more than that with DXA, and the difference was statistically significant (F = 0. 004). In patients with chronic kidney disease，DXA showed high T values while QCT showed normal bone mass. Conclusion For patients with obesity, vertebral degeneration, or chronic kidney disease, QCT should be used to evaluate their BMD. BMD is more accurately evaluated by QCT than by DXA in Tibetan patients. [ABSTRACT FROM AUTHOR]
