目的分析MRI多序列扫描诊断 乳腺癌的临床价值。方法 收集2013年1 月-2017年4月于我院进行乳腺MRI检查的 150例乳腺肿瘤患者的临床资料，所有患 者入院后均接受1.5T MRI常规平扫、动 态增强成像(DCE)、扩散加权成像(DWI) 检查，分析MRI多序列扫描诊断乳腺癌的 临床价值。结果 MRI不同序列诊断乳腺 癌以DWI序列诊断效能最高，敏感性、特 异性及准确率分别为93.40%、75.00%、 88.00%，其次为DCE扫描，敏感性、特异 性及准确率为86.79%、61.36%、79.33%； MRI平扫综合价值最低，敏感性、特异性 及准确率为73.58%、50.00%、66.67%。结 论 MRI DWI序列诊断乳腺癌综合价值最 高，其次为MRI动态增强扫描。

Objective To analyze the clinical value of MRI multi-sequence scan in the diagnosis of breast cancer. Methods The clinical data of 150 patients with breast cancer examined by MRI in the hospital from January 2013 to April 2017 were collected. All the patients underwent 1.5T conventional MRI scan, dynamic contrast-enhanced imaging (DCE) and diffusion weighted imaging (DWI) examination. The clinical value of MRI multi-sequence scan in the diagnosis of breast cancer was analyzed. Results The diagnostic efficiency of DWI sequence in different MRI sequences was the highest, and the sensitivity, specificity and accuracy were 93.40%, 75.00% and 88.00%, respectively, followed by DCE scan, and the sensitivity, specificity and accuracy were 86.79%, 61.36% and 79.33%, respectively. The synthetic value of MRI plain scan was the lowest, and the sensitivity, specificity and accuracy were 73.58%, 50.00% and 66.67%, respectively. Conclusion The comprehensive value of MRI DWI sequence is the highest in the diagnosis of breast cancer, followed by MRI dynamic contrast- enhanced scan.
