摘要
目的分析脊椎MRI检查与放射性核素骨显像(简称骨显像)对乳腺癌脊椎转移灶的诊断价值。方法对比分析41例乳腺癌合并脊椎转移患者的脊柱MRI与骨显像对转移脊椎个数的检出结果,比较MRI与骨显像对脊椎骨转移灶的检出能力。结果经临床及病理证实,41例患者共205个椎体和(或)其附件有转移灶,脊柱MRI检出197个,占96%,骨显像检出168个,占82%,MRI的检出率高于骨显像的检出率,二者差异有统计学意义(χ2=8.214,P=0.004)。结论 MRI对乳腺癌脊椎转移诊断的敏感性及特异性均高于骨显像,对早期诊断脊椎骨转移有重要价值。
Objective To compare the diagnostic efficacy of MRI and bone scintigraphy on vertebral metastases in patients with breast cancer.Methods 41 patients of breast cancer and clinically confirmed metastatic disease in spine underwent MRI and bone scintigraphy examination.The number of involved vertebri diagnosed with two methods were calculated and compared retrospectively.Results A total of 205 vertebral metastases were found in 41 patients,among which 197（96%,197/205） were detected with MRI and168（82%,168/205） with bone scintigarphy.Conclusion Compared with bone scintigraphy,MRI is superior in detecting vertebral metastases from breast cancer,and plays an important role in the early diagnosis of spinal metastases from breast cancer.
