目的探讨~(99m)锝-亚甲基二磷酸盐[(99m)Tc-methylene diphosphonate,~(99m)Tc-MDP]三相骨显像对疲劳性骨膜炎的诊断价值。方法将41例疲劳性骨膜炎患者按腿部疼痛出现后是否继续训练分为A、B两组,分别行三相骨显像及X线检查。分析并总结两组疲劳性骨膜炎在血流灌注相、血池相及延迟相中的放射性分布特点,并对患侧感兴趣区(region of interest,ROI)/健侧ROI的放射性计数比值进行比较分析。结果病变部位于血流灌注相、血池相及延迟相均可见异常放射性增强灶;发病后继续训练的患者患侧ROI/健侧ROI血池相及延迟相的放射性计数比值均大于发病后立即停止训练的患者。结论三相骨显像能够全面综合的观察疲劳性骨膜炎病变部位动脉血流灌注、血管床和骨盐代谢情况,对于疲劳性骨膜炎早期诊断有重要意义;还可判断疲劳性骨膜炎的轻重程度以及与训练的关系,对于该病的临床治疗以及部队合理训练新兵起到重要作用。
Objective To investigate the diagnostic value of ~ (99m) Tc-methylene diphosphonate, ~ (99m) Tc-MDP] three-phase bone scintigraphy in the diagnosis of fatigue periostitis. Methods A total of 41 patients with fatigue periarthritis were divided into group A and group B according to their pain after leg pain. Three-phase bone imaging and X-ray were performed respectively. The characteristics of radioactive distribution in the perfusion phase, blood pool phase and delayed phase in the two groups were analyzed and summarized, and the ratio of radioactive count in the region of interest (ROI) / contralateral ROI was calculated comparative analysis. Results The lesions were located in the perfusion phase, the pool of blood pool and the delayed phase were abnormal radioactive enhanced focus; patients with follow-up after the onset of ipsilateral ROI / contralateral ROI blood pool phase and delayed phase radioactivity count ratio were greater than immediately after onset Stop training patients. Conclusion Three-phase bone scintigraphy can comprehensively and comprehensively observe the arterial perfusion, vasculature and bone salt metabolism in patients with fatigue periostitis, and is of great significance for the early diagnosis of fatigue periostitis. It can also determine the severity of fatigue periostitis The level and the relationship with training play an important role in the clinical management of the disease and the reasonable training of recruits by recruits.
