摘　　要：目的　评价９９ｍＴＣ－ ＭＤＰ骨显象检测复合珊瑚骨移植成骨情况。方法　通过动物实验和临床病例观察，采用９９ｍＴＣ－ ＭＤＰ、组织学检查和Ｘ线检查动态观察复合珊瑚骨移植后的成骨情况。结果　动物实验，核素骨显像能在３ 周对植入骨的成骨作出预测，较Ｘ 线早３ 周；临床上，该方法能在术后１ 个月预测植入骨成骨情况，较Ｘ线早２ 个月。结论　核素骨显像能较早地预测植入骨的成骨情况。Objective To evaluatethe osteogenesisaftercompositecoralgrafting with 99mTc- MDPimaging. Methods 99mTc- MDPboneimaging,radiography and histology were utilized experimentally and clinically to observethe os teogenesisat different period aftercompositecoralgrafting.Results Scintigraphy may predictthe graftfate atthe 3rdweek postoperativelyin experimentalstudy,three weeks earlierthan radiography. This method may predictthe graft fatebythe end ofthe first month clinically,preceded radiography by 2 months.Conclusion Scintigraphy may offer prediction ofthe graftfateearlier.
