乳腺MR功能成像对乳腺病变的诊断价值研究

目的 探讨乳腺MR功能成像对乳腺病变的诊断价值.方法 选取2014年2月至2016年1月经本院病理诊断为乳腺肿瘤患者90例,其中良性肿瘤50例,乳腺癌40例,并同时予以磁共振扩散加权成像(DWI)、氢离子磁共振波谱(1H-MRS)、动态增强检查对其资料进行检查,并将成型的图像信息分析结果于病理检验结果对比,得出DWI、1H-MRS及动态增强两两结合、三项结合的诊断乳腺癌的准确性、敏感性及特异性.结果 DWI及动态增强联合诊断准确性为86.67％、敏感性为82.50％、特异性为90.00％,其MRS+动态增强联合诊断准确性为83.33％、敏感性为85.00％、特异性为82.00％,其DWI+MRS联合诊断准确性为80.00％、敏感性为75.00％、特异性为84.00％,其DWI+MRS+动态增强联合诊断准确性为97.78％、敏感性为97.50％、特异性为98.00％,与上述三项两两诊断的准确性、敏感性及特异性的结果比较差异有统计学意义(P＜0.05).结论 MRS、DWI及动态增强联合诊断乳腺癌的准确性、敏感性及特异性显著高于单一检查及两项联合检查,值得在临床中推广实施.

Diagnostic value of breast MR imaging in breast lesions

Objective To evaluate the diagnostic value of MR imaging in mammary gland lesions.Methods 90 cases of breast cancer including 50 cases of benign tumor and 40 cases of breast cancer in our hospital from February 2014 to January 2016 underwent magnetic resonance diffusion weighted imaging (DWI),hydrogen ion magnetic resonance spectroscopy (1 H-MRS),dynamic enhancement examination.Compared the formed image information analysis results and the pathological test results,obtained the accuracy,sensitivity,and specificity of the combined diagnosis of DWI,1H-MRS,and dynamic enhancement for breast cancer.Results The accuracy,sensitivity,and specificity of the combined diagnosis of DWI and dynamic enhancement for breast cancer were 86.67％,82.50％,90.00％;those of the combined diagnosis of 1H-MRS and dynamic enhancement for breast cancer were 83.33％,85.00％,82.00％;those of the combined diagnosis of DWI and 1H-MRS for breast cancer were 80.00％,75.00％,84.00％;those of the combined diagnosis of DWI,1 H-MRS,and dynamic enhancement for breast cancer were 97.78％,97.50％,98.00％,which were the highest,with statistically significant differences (P＜0.05).Conclusion The accuracy,sensitivity,and specificity of the combined diagnosis of DWI,1H-MRS,and dynamic enhancement for breast cancer were the highest,which was worth practicing in clinical practice.
