Application of ^(99)Tc^m-MDP Three-Phase Bone Scintigraphy in the Surgery of Chronic Osteomyelitis

目的探讨99Tcm-MDP骨三相显像在慢性骨髓炎外科手术治疗中的作用。方法回顾性分析我科2002~2008年34例慢性骨髓炎患者99Tcm-MDP骨三相显像的资料,结合临床骨科手术方法,探讨99Tcm-MDP骨三相显像对慢性骨髓炎的诊断及治疗价值。结果 34例患者中,28例患者血流相患/健侧摄取比值(A/N比值)明显增加,阳性率为82.4%;血池相10例患者软组织内可见示踪剂异常浓聚,阳性率为29.4%;延迟相34例患者骨骼均可见示踪剂异常浓聚,阳性率为100%。结论核素骨三相显像可以评估病灶的范围、死骨的大小及位置,为术中彻底清除骨性病灶的坏死组织提供正确的指导作用。

Objective To investigate the effect of ^99Tc^m-MDP three-phase bone scintigraphy in the surgery of chronic osteomyelitis. Methods Combined with surgical operation methods, the ^99Tc^m-MDP three-phase bone scintigraphy data of 34 patients with chronic osteomyelitis who were recruited from 2002 to 2008 in our hospital was analyzed to explore the diagnostic and therapeutic value of ^99Tc^m-MDP three-phase bone scintigraphy in chronic osteomyelitis. Results The A/N ratio was increased in 28 patients in blood fl ow phase, which indicated that the positive rate of chronic osteomyelitis in blood fl ow phase was 82.4%. The abnormal gather of tracer agent was occurred in soft tissues of 10 patients in blood pool phase and bones of 34 patients in delayed phase, which indicated that the positive rates of chronic osteomyelitis in blood pool phase and delayed phase were 29.4% and 100%, respectively. Conclusion The scope, position and size of bone lesions can be evaluated with ^99Tc^m-MDP three-phase bone scintigraphy, which can provide a correct guidance for the surgeon to thoroughly remove necrotic tissue of bone lesions.
