全身核素骨显像对食管癌骨转移的诊断

目的：探讨食管癌患核素骨显象表现及胸部术后放疗后局部骨骼变化的鉴别诊断，方法：收集经病理实证的72例管食癌全身骨显像病例，经静脉注射^99mTc亚甲基二磷酸盐（MDP）555－925MBq后3－6h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25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。

Study of Bone Metastasis from Esophageal Carcinoma by Nuclide Imaging of Bone

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.
