转移性骨肿瘤的放射性核素骨扫描与MRI诊断特征分析OA
Analysision of Radionuclide Bone Scan and MRI Diagnostic Characteristics of Metastatic Bone Tumors
目的:探讨与分析转移性骨肿瘤的放射性核素骨扫描与核磁共振成像(MRI)诊断特征,判断诊断价值.方法:选取 2019年 2月—2022年 5月于山东省济南市平阴县中医医院收治的68例恶性肿瘤患者作为研究对象,确诊转移性骨肿瘤的 18例患者作为转移组,确诊其他恶性肿瘤的50例患者作为非转移组,所有患者都给予放射性核素骨扫描-正电子发射计算机断层扫描(PET/CT)和MRI检查,记录影像学特征并进行诊断价值的判定.结果:2组的年龄、体重指数、性别、血压等一般资料对比,组间差异无统计学意义(P>0.05).转移组核磁共振成像的软组织肿块、压迫椎管、瘤周水肿带等占比为 77.8%、72.2%、66.7%,明显高于非转移组的34.0%、44.0%、36.0%,组间差异有统计学意义(P<0.05).SPECT/CT标准摄取值最大值与平均值均高于非转移组,组间差异有统计学意义(P<0.05).在 68例患者中,放射性核素骨扫描诊断为转移性骨肿瘤 22例,MRI诊断为转移性骨肿瘤19例,转移性骨肿瘤的放射性核素骨扫描与MRI诊断的敏感度分别为 81.8.%、94.8%,特异度分别为 94.3%、98.0%,MRI诊断的敏感度高于放射性核素骨扫描诊断,差异有统计学意义(P<0.05),特异度高于放射性核素骨扫描诊断,差异无统计学意义(P>0.05).结论:放射性核素骨扫描与核磁共振成像均可了解转移性骨肿瘤患者的病变信息与病理特征,MRI诊断的敏感性相对更高,有一定的临床应用价值.
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.
