乳腺浸润性导管癌的X线、MR征象对比分析

Comparsion of Mammography and MR Findings of Breast Invasive Ductal Carcinoma

目的:对比乳腺浸润性导管癌X线、MR征象,提高乳腺癌影像诊断正确率。方法:回顾性分析经病理证实的51例乳腺浸润性导管癌的X线和MR常见征象。结果:X线与MR检出肿块、毛刺、边缘分叶、边界不清、恶性钙化、肿瘤血管及腋下淋巴结肿大的例数分别为44,35,30,21,19,1,9及51,33,35,16,0,28,9。MR检出肿块(P=0.006)和肿瘤血管(P<0.001)优于X线,恶性钙化劣于X线(P<0.001),其余指标无明显差异。联合两种检查方法51例病灶术前均得到正确诊断。结论:联合X线及MR检查能够提高乳腺浸润性导管癌诊断正确率。

To investigate mammagraphy and MRI ifndings of breast invasive ductal carcinoma.Methods： Retrospectively analyzed mammography and MRI ifndings of 7 pathology-proved breast invasive ductal carcinomas.Results：The number of mass, spiculation, lobulation, obscure boundary, malignant calciifcation, tumor vessel and enlargement of axillary lymph nodes by mammography and MR were 44,35,30,21,19,1,9 and 51,33,35,16,0,28,9 respectively. MR was superior to detecting mass （P=0.006） and tumor vessel （P〈0.001）, and inferior to mammography in malignant calciifcation （P〈0.001）. All the lesions were diagnosed by the two imaging methods.Conclusion：Accurate diagnosis of breast invasive ductal carcinoma can be reached by using the imaging ifndings of mammography and MRI.
