核素骨显像对肺癌骨转移特点和规律的探讨

目的：用^99Tc-亚甲基二膦酸盐（^99c^-MDP)山对肺癌患者进行全身核素骨显像，探讨肺癌骨转移的特点和规律，方法：收集我院近三年140例肺癌有转移病例，对骨转移的部位，数量与病理类型进行回顾性分析，结果：肺癌骨转移率为34．1％，骨转移部位以胸部骨骼为最多，其次为脊柱和骨盆，肺腺癌，鳞癌较其它类型肺癌更易发生骨转移，全身骨显像诊断肺癌转移的阳性率明显高于X线摄片与X－CT，结论：全身素骨显像对骨转移的诊断最有价值，肺癌患者应常规行全身骨显像随访。

Study of radionuclide bone imaging in diagnosis of skeletal metastases in patients with lung cancer

AIM 99 Tc m MDP bone imaging was performed in patients with lung cancer. Characteristics and regularity of skeletal metastases was investigated. METHODS Bone metastatic sites, quantity and different pathological types were analyzed in 140 cases of skeletal metastases patients with lung cancer in recent three years. RESULTS Total skeletal metastatic rate of lung cancer was 34.1%. Thoracic bones were the most frequent metastatic sites, spinal and pelvic bone were the next. The skeletal metastaese of adenocarcinoma, squamocarcinoma was more easily than other types of cancer. The positive rate of bone metastasis diag nosed by radionuclide bone imaging was rather higher than that of X ray and X CT. CONCLUSION Radionuclide bone imaging should be routinely perfomerd in patients with lung cancer.
