核素骨显像及X线对骨转移癌的诊断价值(附81例病例分析)

VALUE OF RADIONUCLIDE BONE IMAGING AND X RAY IN EVALUATION OF METASTATIC OSTEOMA

目的：探讨核素骨显像、Ｘ线及临床症状对骨转移癌的诊断价值。方法：对８１例恶性肿瘤患者行核素骨显像、Ｘ线平片或局部放大片检查，同时结合患者的临床症状综合分析其诊断价值。结果：有骨痛症状和无骨痛症状的病例核素骨显像阳性检出率分别为８８９％和３３３％，明显高于Ｘ线平片的检出率（６３０％和６３％），有显著性差异。而对于Ｘ线平片有阳性改变者核素显像的检出率为９８％。结论：核素骨显像较Ｘ线平片更早发现骨转移灶。

Objective:To study the value of radionuclide bone imaging,X ray and symptoms in evaluation of metastatic osteoma.Methods:81 cases of carcinoma were studied by using radionuclide bone imaging and X ray.Results:The positive rates of radionuclide bone imaging were 89 1% and 37 5% respectively in all bone symptomatic patients,higher than those of X ray (63 0% and 6 3%) with a significant difference.Radionuclide bone imaging can demonstrate in 98% of cases who have a positive result in X ray.Conclusion:Radionuclide bone imaging can detect a pathogemtic focus in early stage.
