本文采用~(99m)Tc-硫胶体作全身骨髓 r 照相,观察了24例正常人和83例再障患者的全身骨髓分布,并随访观察1年,结合临床资料,探讨核素骨髓显象对再障的诊断、分型及预后判断的意义。~(99m)Tc-硫胶体按文献方法制备,标记率95%以上,胶体颗粒约1～2μm,肘静脉注入6.66MBq(180μCi)/kg 体重,20min 后排空膀胱,取仰、俯 Whole-body bone marrow r imaging with ~ (99m) Tc-sulfur colloids was performed in this study. Whole body bone marrow distribution was observed in 24 normal subjects and 83 patients with aplastic anemia. One year follow-up and clinical data were used to explore the relationship between nuclide bone marrow imaging Aplastic anemia diagnosis, classification and prognostic significance. ~ (99m) Tc-sulfur colloids were prepared by literature method. The labeling rate was above 95%, colloidal particles were about 1-2μm, and 6.66MBq (180μCi) / kg body weight was injected into the elbow vein.
