摘　　要：目的：探讨乳腺 X线摄影、3.0T MR检查及两者联合应用对乳腺良恶性病变的诊断价值。方法收集乳腺 X线摄影、MR检查的女性患者61例,良性14例,恶性47例。所有病例均经手术病理证实。观察病变时间-信号强度曲线（TIC）、表观扩散系数（ADC）值、磁共振波谱（MRS）有无胆碱（Cho）峰。分析单独运用乳腺X线摄影、MR及2种技术联合应用在乳腺良恶性病变的价值。采用 SPSS 17.0统计软件包进行分析,计数资料进行卡方检验,P〈0.05认为差异有统计学意义。结果单独使用乳腺 X线摄影及 MR诊断乳腺良恶性疾病的诊断符合率分别是45.9%、62.3%；两者联合运用诊断乳腺良恶性疾病的符合率为80.3%,均高于单独使用某一种检查（χ2=4.08,P〈0.05）。结论 MR检查对乳腺良恶性病变的诊断价值高于乳腺 X线摄影。乳腺 X线摄影联合 MR检查明显提高乳腺良恶性病变术前诊断的准确率,为早期诊断及预后提供理论依据。Objective To investigate the diagnostic value of mammography,3.0T MR and the combination for benign and malignant breast lesions.Methods Sixty-one patients with breast lesion proved by postoperative pathology included 47 malignant cases and 14 benign cases.Imaging indexes were recorded and analyzed for all cases,including TIC type,ADC value and whether the Choline peak was detected on MRS.SPSS 17.0 statistical software package was used for analysis.Chisquare test was used for count data and P〈0.05 was considered as statistically significant.Results The accuracy were 45.9% and 62.3% respectively for mammography or MR as a sole method for the diagnosis of benign and malignant breast disease.When combining the two techniques,the diagnostic accordance rate was 80.3%.The rate based on the combination of mammography and MR were higher than on basis of either kind of examination along, with a statistically significant difference （χ2=4.08,P〈0.05）.Conclusion MR examination was superior to mammography for the diagnosis value of benign and malignant breast lesions.When combining mammography with MR examination,it could not only obviously improve the accuracy of preoperative diagnosis of breast cancer but also provide the theoretical basis for the early diagnosis and the prognosis.
