摘　　要：目的探讨数字乳腺三维断层融合摄影(DBT)技术对不可触及微小病灶的诊断价值。方法选择2016年5月至2017年12月在秦皇岛市妇幼保健院临床查体不可触及但超声提示乳腺病灶直径≤1 cm患者50例进行回顾性研究,对其进行全数字化乳腺X线摄影(FFDM)和DBT检查,最后与手术病理结果进行对照,了解DBT对微小病灶的诊断价值。结果 50例乳腺超声提示病灶直径≤1 cm的低回声,超声分级4级1例,FFDM 4级1例,DBT分级4级4例,各分级4级病例经病理证实均为乳腺癌,DBT检出乳腺癌敏感度为80%。结论 DBT可提高良恶性病变的鉴别诊断能力,特别是对于超声提示的不可触及的微小病灶的诊断具有重要的意义。Objective To explore the diagnostic significance of digital breast tomosynthesis （DBT） for non palpable small lesions. Methods A total of 50 cases of breast lesions with diameter less than 1 cm were found in this hospital during May 2016 to December 2017., and the total digital mammography （FFDM） and DBT were examined. Finally, the diagnostic significance of DBT for small lesions was compared with the pathological results of operation. Results 50 cases of breast ultrasound showed the low echo of these lesions with diameter less than 1 cm, 1 cases of ultrasonic grade 4, 1 case of FFDM grade 4, 4 cases of DBT grade 4, all these cases with grade 4 were breast cancer confirmed by pathological examination, and the sensitivity of DBT for breast cancer was 80%. Conclusion DBT can improve the ability of differential diagnosis on benign and malignant lesions, especially for the diagnosis of non palpable small lesions promptly discovered by ultrasounography.
