【摘要】 目的　探讨食管癌患者核素骨显象表现以及胸部术后放疗后局部骨骼变化的鉴别诊断。方法　收集经病理证实的 72例食管癌全身骨显像病例。经静脉注射 99m Tc-亚甲基二磷酸盐 (MDP) 5 5 5～ 92 5 MBq后 3～ 6 h进行全身骨显像检查。结果　骨放射性异常浓聚 40例 ,其中多骨性、多灶性浓聚 2 5例 ,单骨性浓聚 15例 ,病灶以胸椎、肋骨、骨盆多见。结论　放射性核素骨显像对食管癌患者除可显示病骨浓聚转移灶外 ,还应注意手术及放疗后 ,对胸部相应骨骼所造成的影响更多还原

【Abstract】 Objective To investigate nuclide image of Bone of patients with esophageal carcinoma and differential diagnosis for local bone change after radiotherapy for chest.Methods Systemic bone image was carried out in 72 cases of esophageal carcinoma,confirmed by pothology,after injection of 99mTc-MDP(555～925MBq) through vein for 3～6 hours.Results Unusual concentration of eadionuclide in bone was observed in 40 cases,including 25 cases of multi bone or multi local concentration and 15 cases of monolocal concentration with lesion presence mainly in vertebrae thoracales,os costae and pelvis.Conclusion Bone image with radionuclide may manifest nuclide concentration of metastated bone.The effect of operation and radiotherapy on bones of chest should be paid attention.更多还原
