Measurement of bone marrow measurements may occur if bone marrow examination performed with bone marrow examination (bone marrow examination) and bone density (bone scan) are performed together recently. Thus, it was examined in clinical aspects that 99mTc-MDP compounds were affected by bone mineral density measurements. The average age of the participants in the experiment was 35.17±9.45 and the patient fractures of the lumbar vertebrae that could affect the metabolic disease and bone density measurements affecting the metabolic disease of the 17 subjects. 6 patients with normal bone mineral density T-scores>-1.0 in 12 patients were analyzed before and after the administration of 99mTc-MDP. In the lumbar spine, the average of 0.975±0.084 g/㎠ and 0.966±0.078 g/㎠ were increased by 0.009 g/㎠. respectively In the right proximal femur, mean values were 0.909±0.078 g/㎠ and 0.913±0.086 g/㎠. In the right proximal thigh, mean values were 0.909±0.078 g/㎠ and 0.913±0.086 g/㎠, respectively, which decreased by 0.004 g/㎠. In the left side proximal femur, mean 0.887±0.099 g/㎠ and 0.881±0.103 g/㎠, respectively, increased by 0.007 g/㎠. Therefore, the BMD changes in the lumbar region were larger than that in the proximal thigh. In addition, 99mTc-MDP did not affect the BMD. And a bone scan test using a technetium-labeled compound emitting a gamma-ray energy of 140 keV did not significantly affect bone density measurements. However, if the nuclear medical examination and the osteoporosis test are to be performed together, the examination should be carried out at intervals considering the exposures of the patient.
