摘　　要：采用骨闪烁显像术，对１００例接受新兵军事训练９周期间发生下肢骨应力性骨折症状的患者，进行早期影像学诊断．共检出８６例２１７个病变，其中Ⅰ～Ⅱ级的轻度病变占９６．３％，无症状病变占３２．７％．以骨闪烁显像作为早期诊断应力性骨折的金标准，对比观察同批患者１３４处骨折病变同期的Ｘ线摄片诊断结果．采用的常规Ｘ线摄片法仅发现１３处病变，阳性率９．７％．对８６例患者每例的病变数、病变等级及好发部位等指标也进行了分析．Abstract Stress fracture(SF)in 100 recruits during 9 weeks basic military training was investigated using 99mTc-MDP bone scintigraphy.In 86 persons,217 SF foci were find,among them 32.7% of the lesions were asymptomatic.96.3% (209 SF) of the lesions were mild classified as Ⅰ￣ Ⅱ grade. Using radionuclide bone images as a golden standard for early detection,the comparative results showed 134SF fool detected by the radionuclide image while only 13 SF foci on the X-ray film.Therefore,the bone scintigraphy is much more sensitive than radiography for diagnosing stress fractures.The number,grading and site of SF in 86 persons were also demonstrated and discussed.
