| 摘要目的：分析早期乳腺癌的全数字X 线摄影与MRI影像学表现，评价全数字X 线摄影联合MRI 检查在早期乳腺癌诊断中的
临床价值。方法：回顾性分析2009 年10 月至2012 年5月在我院经穿刺或手术病理证实为早期乳腺癌的42例患者的临床资料，
术前均行数字X线及动态增强MR 检查，比较两种方法单独使用和联合使用的诊断乳腺癌的准确率。结果：全数字化X 线摄片
诊断早期乳腺癌的准确率为69.0%(29/42)，动态增强MR 检查为95.2%(40/42)，两者比较差异有统计学意义(P<0.05)；两者联合使
用诊断早期乳腺癌的准确率为97.6%(41/42)。结论：动态增强MR 检查对早期乳腺癌的诊断价值明显优于全数字X线摄影，但后
者对微小钙化显示较好，两者联合可提高诊断正确率，尤其对多腺体型和致密型乳腺的早期乳腺癌的检出具有重要的价值。 |

| ABSTRACT Objective:To analyze the imaging features of early breast cancer by full-field digital mammography (FFDM) and
magnetic resonance (MR), and study the clinical significance of mammography combined with MR in the diagnosis of early breast
cancer. Methods:29 patients with early breast cancer confirmed with needle biopsy or pathology from Oct. 2009 to May. 2012 were
reviewed. These patients underwent both mammo and dynamic contrast-enhanced MR imaging (DCE-MRI) before operation to compare
the preoperative diagnostic accuracy by using mammo and DCE-MRI each alone and in combination. Results:The diagnostic accuracy of
mammography was 69.0%(29/42) in the diagnosis of early breast cancer, which was 95.2%(40/42) of DCE-MRI (P<0.05) and 97.6 %
(41/42) of the combination of both methods. Conclusion:The diagnostic value of DCE-MRI for early breast cancer was more superior to
mammo, however the latter showed better microcalcifications, combination of the two methods could increase the diagnostic accuracy,
and had very important value for the detection of early breast cancer, especially for heterogeneous type and dense-type. |
