目的对比乳腺钼靶摄影和增强 磁共振在诊断乳腺癌中的优劣势，评价两 种检查方式的价值。方法 对71例乳腺包 块患者的X线钼靶片、MRI片及病理检查 结果进行回顾性分析，计算出两种检查 方法对乳腺癌检出的灵敏度、特异度及 准确度。结果 乳腺钼靶对乳腺癌检出的 灵敏性、特异性及准确性分别为59.5%、 62.1%、 60.6%，增强MRI对乳腺癌检出的 灵敏性、特异性及准确性分别为76.2%、 79.3%、77.5%。MRI对乳腺癌的检出率要 高于钼靶摄影，两者之间差异有统计学意 义(χ2 =5.142，P<0.05)。结论 在对乳腺 癌检出的灵敏度、特异度及准确度上， MRI均优于钼靶，两者之间存在显著性差 异。

Objective Contrast of mammary gland molybdenum target photography and enhanced MRI in the diagnosis of breast cancer, the advantages and disadvantages in the evaluation of the value of two inspection ways. Methods A retrospective analysis of 71 patients with breast mass X-ray mammography, MRI and pathological examination results, calculate the two inspection methods for breast cancer detection accuracy and sensitivity, specific degrees. Results Mammary gland molybdenum target in breast cancer detection sensitivity, specificity and accuracy were 59.5%, 62.1%, 60.6%, enhanced MRI for breast cancer detection sensitivity, specificity and accuracy were 76.2%, 79.3% and 77.5% respectively. MRI for breast cancer detection rates are higher than molybdenum target photography, the difference was statistically significant between the two (χ2 =5.142, P<0.05). Conclusion In the breast cancer detection accuracy and sensitivity, specific degrees, MRI is superior to mammography, significant differences between the two.
