| 目的 探讨MRI对乳腺癌术前评估的价值,并与X线摄影、超声比较。 方法 35例经手术病理证实的乳腺癌患者,术前均接受乳腺动态增强MRI、X线摄影及彩色多普勒超声检查。病理类型包括浸润性导管癌28例,导管内癌伴局灶浸润3例,导管内癌2例,黏液腺癌合并广泛高级别导管内癌1例,浸润性小叶癌1例。其中病理报告局部多灶5例,导管内播散10例。将三种影像学方法对乳腺癌的检出、病变大小及范围与病理结果进行对照。 结果 MRI、X线摄影和超声检查对乳腺癌的检出率分别为100%、74.29%和82.86%。MRI对乳腺癌患者的检出率明显高于X线和超声(P<0.05)。MRI、X线和超声检查对病灶大小评价与病理结果进行相关性分析,相关系数r分别为0.94、0.87、0.70,均具有显著性统计学意义(P<0.01)。MRI、X线摄影和超声检查对局部多灶及导管内播散诊断的灵敏度、特异度、准确率分别为100%、80.00%、88.57%;66.67%、95.00%、82.86%;33.33%、95.00%、68.57%;其中MRI灵敏度明显高于X线摄影(P=0.042)和超声检查(P=0.000)。 结论 MRI在乳腺癌术前检出、病变大小及范围评估方面优于X线摄影和超声检查。 |

| Objective To investigate the clinical value of MRI in the preoperative evaluation of breast cancer compared with mammography and ultrasonography. Methods A total of 35 patients with breast cancer were examined preoperatively with dynamic contrast enhanced MRI, mammography and ultrasonography. The findings were evaluated and compared with surgical biopsy. Results The detection rates of breast cancer with MRI, mammography and ultrasonography was 100%, 74.29% and 82.86%, respectively. MRI, mammographic and ultrasonographic measurement of tumor size had correlation coefficient to pathologic findings (r=0.94, 0.87, 0.70, respectively). The sensitivity, specificity, and accuracy of detection of intraductal spread of MRI, mammography and ultrasonography was 100%, 80.00% and 88.57% (P<0.05), 66.67%, 95.00% and 82.86% (P>0.05), 33.33%, 95.00% and 68.57% (P>0.05), respectively. Conclusion MRI can detect breast cancer, especially intraductal spread more sensitively than mammography and ultrasonography. |
