摘要
目的对比分析核素骨扫描与磁共振全身扩散加权成像对骨转移瘤的诊断效能。方法选择2015年1月~2017年1月确诊为恶性肿瘤并疑似存在骨转移的患者55例,治疗前分别进行核素骨扫描和磁共振全身扩散加权成像,两种检查间隔<1周,分析两种方法得出的结论,对比分析两种方法的灵敏度和特异性。结果两种方法检查提示存在骨转移患者38例,经骨活检病理及随访观察确诊26例,其中核素骨扫描阳性23例,灵敏度为95.83%,特异性为70.96%,准确性为81.81%,磁共振全身扩散加权成像阳性20例,灵敏度为86.96%,特异性为93.75%,准确率为90.91%。两种诊断的灵敏度、准确性比较差异均无统计学意义(P>0.05),而特异性比较差异有统计学意义(P<0.05),磁共振全身扩散加权成像检查的特异性更高。结论目前诊断恶性肿瘤骨转移仍以核素骨显像为首选,磁共振全身扩散加权成像作为补充检查手段可提高诊断的特异性,两者综合运用,有助于恶性肿瘤骨转移的早期诊断。
Objective To compare the diagnostic efficacy of nuclide bone scan and magnetic resonance general diflhsion- weighted imaging （DWI） in the diagnosis of }）one metastases. Methods From January,, 2015 to January,, 2017,55 patients diagnosed as malignant tumors and suspected bone metastases were selected.And then, radionuclide bone scan and magnetic resonance general DWI was respectively performed betfore treatment.Interval between the two methods was less than 1 week. The conclusions of the two methods were analyzed, and sensitivity and specificity were compared.Results The examination of the two methods suggested that 38 patients had bone metastases,26 of them were confinned by bone biopsy and follow-up visit, of which 23 were positive in radionuclide bone scan, sensitivity was 95.83%, specificity was 70.96% and accuracy was 81.81%.Magnetic resonance general DWI was positive in 20 cases, sensiticity was 86.96%, specificity was 93.75% and accuracy was 90.91%.Difference of the sensitivity and accuracy between the two diagnostic methods was not statistically significant （P〉0.05）, but thai of specificity was statistically significant（ P〈0.05 ）.The specificity of magnetic resonance general DWI was higher.Conclusion At present,radionuclide hone imaging is still the first choice in the diagnosis of hone metastasis of malignant tumor. Magnetic resonance general DWI, as a supplementary examination, can improve the specificity of diagnosis. The combined use of them is helpful to the early diagnosis of hone metastasis of malignant tumor.
