WB-DWI与ECT骨显像在肺腺癌全身骨显像骨转移的应用

目的观察肺腺癌全身骨显像骨转移使用核磁共振(Magnetic Resonance Imaging,MRI)全身弥散成像(Whole-body diffusion-weighted imaging,WB-DWI)与发射型计算机断层扫描仪(Emission Computed Tomography,ECT)骨显像诊断价值。方法回顾性分析我院2015年5月至2018年5月收治经病理检查确诊的肺腺癌患者312例,均实施MRI全身弥散成像与ECT骨显像。观察两种诊断方式检出率及诊断效能。结果 315例患者肺癌患者中骨转移患者131例(41.59%)。MRI全身弥散成像准确率为32.70%与ECT骨显像检查诊断的32.06%比较,差异无统计学意义(P>0.05)。MRI全身弥散成像特异度、准确性、阳性预测值均优于ECT骨显像(P<0.05)。结论肺腺癌全身骨显像骨转移使用MRI全身弥散成像与ECT骨显像均有一定诊断价值,其中MRI全身弥散成像特异度、准确性、阳性预测值优于ECT骨显像。

Application of WB-DWI and ECT Bone Imaging in Bone Metastasis of Lung Adenocarcinoma Whole-body Bone Imaging

Objective To observe the diagnostic value of magnetic resonance imaging(MRI) whole-body diffusion-weighted imaging(WB-DWI) and emission computed tomography(ECT) bone imagingin bone metastasis of lung adenocarcinoma whole-body bone imaging. Methods The 312 patients who were confirmed with lung adenocarcinoma by pathological examination and admitted to the hospital during the period from May 2015 to May 2018 were retrospectively analyzed. All underwent MRI WB-DWI and ECT bone imaging. The detection rates and diagnostic efficiency of the two diagnostic methods were observed. Results Of the 315 patients with lung cancer, there were 131(41.59%) cases with bone metastasis. There was no significant difference in diagnostic accuracy rate between MRI WB-DWI and ECT bone imaging(32.70% vs 32.06%)(P>0.05).The specificity, accuracy and positive predictive value of MRI WB-DWI were better than those of ECT bone imaging(P<0.05). Conclusion There is certain diagnostic value of MRI WB-DWI and ECT bone imaging in bone metastasis of lung adenocarcinoma whole-body bone imaging. The specificity, accuracy and positive predictive value of MRI WB-DWI are better than those of ECT bone imaging.
