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分析

Value of Dynamic Enhanced MRI and Breast DR Mammography in the Diagnosis of Dense Breast Cancer in T1 and Tis Phases

目的分析动态增强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。方法选择昆山市第二人民医院2017年6月至2019年3月收治的T1及Tis期女性乳腺癌患者55例,所有患者均经病理学检查确诊,均进行动态增强MRI与乳腺DR钼靶检查,比较两种检查方法对致密型乳腺T1及Tis期乳腺癌的诊断效能。结果动态增强MRI对致密型乳腺T1及Tis期乳腺癌检出率大于乳腺DR钼靶(P<0.05),动态增强MRI对致密型乳腺T1及Tis期乳腺癌分级诊断总准确率大于乳腺DR钼靶(P<0.05)。致密型乳腺T1及Tis期乳腺癌病灶ADC值为(0.682±0.161)×10-3mm2/s,显著低于正常乳腺组织的(2.104±0.107)×10-3mm2/s(P<0.05)。结论动态增强MRI对致密型乳腺T1及Tis期乳腺癌检出及分级诊断准确性优于乳腺DR钼靶。

Objective To analyze the value of dynamic enhanced MRI and breast DR mammography in diagnosising dense breast cancer in T1 and Tis phases.Methods A total of 55 women with breast cancer in T1 and Tis phases who were admitted to the Second People’s Hospital of Kunshan from June 2017 to March 2019 were selected.All patients were diagnosed by pathological examination and give dynamic enhanced MRI and breast DR mammography.The diagnostic efficacy of the two examination methods was compared in the diagnosis of dense breast cancer in T1 and Tis phases.Results The detection rate of breast cancer by dynamic enhanced MRI was higher than that of breast DR mammography in dense breast cancer in T1 and Tis phases(P<0.05).The overall accuracy rate of dynamic enhanced MRI for grading diagnosis of dense breast cancer in T1 and Tis phases was greater than that of breast DR mammography(P<0.05).The ADC value of dense breast cancer in T1 and Tis phases was significantly lower than that of healthy normal breast tissue[(0.682±0.161)×10-3 mm2/s vs(2.104±0.107)×10-3 mm2/s](P<0.05).Conclusion Dynamic enhanced MRI is superior to breast DR mammography in detecting and grading dense breast cancer in T1 and Tis phases.
