摘　　要：目的探讨数字钼靶X线与DCE-MRI对乳腺癌的诊断价值。方法收集经病理证实的乳腺癌病例31例,回顾性分析其数字钼靶X线及DCE-MRI影像学特点,并与手术结果进行对比。结果 31例病例中,数字钼靶X线阳性发现29例,诊断正确24例,准确率为77.4%(24/31);DCE-MRI阳性发现31例,诊断正确27例,准确率为87.1%(27/31),两者联合应用阳性发现31例,诊断正确29例,准确率为93.5%(29/31)。结论数字钼靶X线与DCE-MRI对乳腺癌的术前诊断价值各有优劣,两者联合应用可提高乳腺癌的检出率及诊断准确率。Objective To investigate the diagnostic value of digital mammography and dynamic contrast - enhanced MRI in breast cancer. Methods 31 cases of breast cancer confirmed by pathology, and retrospective analysis of the digital mammography and dynamic contrast - enhanced MRI findings. Results In the 31 cases： digital mammography positive findings in 29 cases, and correctly diagnosed 24 cases, the accuracy was 77.4% （24/31 ） ; dynamic contrast - enhanced MRI positive findings in 31 cases, and correctly diagnosed 27 cases, the accuracy was 87.1% （27/31）, combination of the two positive findings in 31 cases, and correctly diagnosed 29 cases, the accuracy was 93.5% （29/31）. Conclusions The diagnosis of digital mammography and dynamic contrast- enhanced MRI both have advantages and disadvantages, their combination can improve the detection rate and the correct diagnostic rate of breast cancer.
