摘要：

目的：比较动态增强MRI与乳腺DR钼靶对致密型乳腺T1及Tis期乳腺癌诊断的价值。方法：选取72例致密型乳腺患者，分别进行动态增强MRI检查及乳腺DR钼靶检查，采用χ²检验比较两种检查中T1及Tis期乳腺癌的检出率和诊断准确率。结果：对致密型乳腺患者，T1及Tis期乳腺癌的检出率动脉增强MRI为79.17%（57/72），乳腺DR钼靶为41.67%（30/72），两者差异有统计学意义（P<0.05）；动脉增强MRI检查的准确率为72.22%（52/72），乳腺DR钼靶检查的准确率为37.50%（27/72），两者差异也有统计学意义（P<0.05）。结论：动脉增强MRI能明显提高致密型乳腺患者中T1及Tis期乳腺癌的检出率及准确率。

Objective:To compare the value of dynamic contrast-enhanced MRI(DCE-MRI) and breast DR mammography in the diagnosis of T1 and Tis breast cancer of dense gland. Methods:Seventy-two patients with dense glandular type were examined by DCE-MRI and DR mammography respectively. The detected ratio and diagnostic accuracy of the two methods were compared by chi square test.Results:Detected ratio of the T1 and Tis breast cancer of dense gland was 79.17%(57/72) by DCE-MRI and 41.67%(30/72) by DR mammography, the difference was statistically significant (P<0.05);Accuracy ratio was 72.22% (52/72) by DCE-MRI examination and 37.50% (27/72)by DR mammography examination, the difference was statistically significant (P<0.05).Conclusion:DCE-MRI can significantlly improve the detection ratio and accuracy ratio for T1 and Tis breast cancer in dense breast.
