摘要
目的:探讨全身MRI和骨扫描对乳腺癌患者骨转移首诊的准确性。方法:对22例乳腺癌患者行全身MRI和骨扫描检查以确定有无骨转移。结果:全身MRI和骨扫描诊断骨转移的敏感度、特异度、准确度分别为91.7%、90%、90.9%和83.3%、80%、81.8%;阳性和阴性似然比分别为9.17、0.11和4.16、0.24。结论:乳腺癌患者骨转移全身MRI效果优于骨扫描。
Objective To assess the diagnostic accuracy of whole-body MRI(WB-MRI) and bone scintigraphy(BS) for osseous metastasis in patients with breast cancer.Methods Twenty-two patients with breast cancer were underwent both planar BS and WB-MRI,in order to determine whether there were osseous metastases.Results The sensitivity,specificity,diagnostic accuracy,positive and negative likehood ratio of WB-MRI were 91.7%,90%,90.9%,9.17 and 0.11 and for BS those were 83.3%,80%,81.8%,4.16 and 0.24,respectively.Conclusion The diagnostic efficacy of WB-MRI was superior to BS for osseous metastasis in patients with breast cancer.
