钼靶结合MRI对微小乳腺癌的诊断价值分析

目的：探讨全数字化X线乳腺钼靶摄影、3.0 T MRI检查对微小乳腺癌的诊断价值。材料与方法回顾性分析31例经手术证实的微小乳腺癌患者的全数字化X线乳腺钼靶及3.0 T MRI检查资料，分析其影像学特征，并统计对比钼靶、MRI单独和联合应用的诊断准确率。结果 X线乳腺钼靶摄影准确率为64.5%(20/31)，MRI 检查诊断准确率为90.3%(28/31)，联合应用诊断准确率为96.7%(30/31)，高于两者单独应用，差异有统计学意义(P＜0.05)。结论微小乳腺癌X线乳腺钼靶摄影、MRI表现具有一定的特征性，两者联合应用有助于提高乳腺癌的诊断正确率。

Value of digital X-ray mammography and 3.0 T MRI in the diagnosis of small breast cancer

AbrtractObjective:To investigate the value of X-ray mammography and 3.0 T MRI in the diagnosis of the small breast cancer.Materials and Methods:A total of 31 patients with small breast cancer conifrmed by surgery and pathology were reviewed retrospectively, including digital X-ray mammography and 3.0 T MRI image features. Results:The diagnosis accuracy of small breast cancer by digital X-ray mammography was 64.5% (20/31) , the diagnosis accuracy of small breast cancer by 3.0 T MRI was 90.3% (28/31) , the diagnosis accuracy of small breast cancer by X-ray mammography and MRI was 96.7% (30/31) , which was the highest (P<0.05).Conclusion:There are certain characteristics for breast cancer on X-ray mammography and MRI, which can help make correct diagnosis for it.
