Application of include and exclude function to regions of interest in bone mineral density measurement

Objective To observe the bone mineral density(BMD) of the special cases with the analyses function of Dual Energy X-Ray Bone Densitometer.Methods BMD in the special cases were measured by NORLAND XR46 Dual X-Ray Bone Densitometer.The software of including and exclude function(IE) was used to analyze the imaging and BMD by setting manually the analytic regions or removing special regions.Results All area in regions of interest(ROI) were showed by IE.The number of BMD and BMC by comparison of pre-and post-treatment with IE had statistical significance(P0.01).Conclusion The measuring errors of BMD caused by the automatic analysis of instrument may be corrected and the real results of BMD measurement may be revealed by this method.
