目的 总结全视野数字化乳腺摄影（Full-Field Digital Mammography,FFDM）结合数字乳腺三维断层摄影技术（Digital Breast Tomosynthesis,DBT）对乳腺疾病的诊断价值。方法 选取2014年1月1日—2014年12月31日进行乳腺钼靶检查的506例病例,分别对其FFDM和DBT影像进行分析,将其乳腺影像报告和病理结果进行对比,详细分析两者单独及联合应用对乳腺疾病诊断的敏感性、特异性和准确性。结果 506例女性（双侧乳腺）术前乳腺X线结果如下：FFDM结合DBT：良性202例（39.9%）,恶性304例（60.1%）;单独FFDM：良性194例（38.3%）,恶性312例（61.7%）;单独DBT：良性187例（37.0%）,恶性319例（63.0%）。病理结果：良性214例（42.3%）,恶性292例（57.7%）。在敏感性、特异性和准确性上,

英文摘要：

Objective To explore the diagnostic value of full - field digital mammography （ FFDM） combined with digital breast tomosynthesis （DBT） in breast diseases. Methods 506 patients receiving mammary gland molybdenum target inspection from January 1, 2014 to December 31 , 2014 were selected. The images from FFDM and DBT were analyzed, re-spectively. The breast imaging reports and pathological results were compared to investigate the sensitivity, specificity and ac-curacy of FFDM, DBT alone and combined use of DBT and FFDM. Results The results of preoperative mammography in the 506 women （bilateral breast） were as follows： FFDM combined with DBT detected 202 benign cases （39.9% ） and 304 ma-lignant cases （60. 1% ） ; FFDM alone detected 194 benign cases （38. 3% ） and 312 malignant cases （61.7% ） ; DBT alone detected 187 benign cases （37.0% ） and 319 malignant cases （63.0% ）. Pathologically, 214 benign cases （42.3% ） were detected and 292 malignant cases （51.1%）. In terms of the sensitivity, specificity and accuracy, The combined use of DBT combined with FFDM was the best, followed by FFDM alone and DBT alone. Conclusion The sensitivity, specificity and accuracy of FFDM combined with DBT for diagnosis are better than those of FFDM alone or DBT alone.
