Abstract
Objective:To evaluate the diagnostic value of radionuclide bone scanning and magnetic resonance imaging(MRI)in metastatic bone tumors.Methods:68 patients with malignant tumors admitted to Pingyin Hospital of Traditional Chinese Medicine of Jinan City,Shandong Province from February 2019 to May 2022 were selected as the study objects,18 patients with confirmed metastatic bone tumors were selected as the metastatic group,and 50 patients with confirmed other malignant tumors were selected as the non-metastatic group.All patients were given radionuclide bone scanning-positron emission computed tomography(PET/CT)and MRI to record imaging features and determine diagnostic value.Results:There were no significant differences in age,body mass index,gender and blood pressure between the two groups(P>0.05).The proportion of soft tissue mass,vertebral canal compression and peritumoral edema in MRI in the metastatic group was 77.8%,72.2%and 66.7%,which were significantly higher than 34.0%,44.0%and 36.0%in the non-metastatic group,and the differences between groups were statistically significant(P<0.05).The maximum and average values of SPECT/CT were higher than those of non-metastatic group,and the difference between groups was statistically significant(P<0.05).Among the 68 patients,22 cases were diagnosed with metastatic bone tumor by radionuclide bone scan and 19 cases were diagnosed with metastatic bone tumor by MRI.The sensitivity and specificity of radionuclide bone scan and MRI were 81.8%and 94.8%,respectively,and 94.3%and 98.0%,respectively,the sensitivity of MRI diagnosis was higher than that of radionuclide bone scan diagnosis,the difference was statistically significant(P<0.05),and the specificity was higher than that of radionuclide bone scan diagnosis,the difference was not statistically significant(P>0.05).Conclusion:Both radionuclide bone scan and magnetic resonance imaging can understand the pathological information and pathological characteristics of patients with metastatic bone tumors.MRI diagnosis is relatively sensitive,and has certain clinical application value.关键词
