数字化乳腺断层摄影技术在乳腺癌诊断中的应用价值

目的:探讨数字化乳腺断层摄影技术（DBT）联合全数字化乳腺摄影（FFDM）技术在乳腺癌中的应用价值。方法:回顾性分析70例行FFDM摄影并加照DBT摄影的乳腺癌病人资料，对常规FFDM图像（头尾位+内外斜位）诊断结果，与联合（常规FFDM图像外和DBT图像组作为补充）诊断结果进行比较，记录2组图像中病灶的显示、边缘细节及周围征象显示等情况，采用乳腺影像报告及数据系统对病变进行评估。结果:常规FFDM图像诊断恶性病变46例，良性病变24例；评价结果与病理结果符合率约66%；联合诊断恶性病变57例，良性病变13例；评价结果与病理结果符合率约81%。2种评价结果的差异均有统计学意义（P<0.05）。结论:DBT检查技术能够提高乳腺癌病灶的显示及诊断效能，在一定程度上提高了早期乳腺癌的诊断水平，具有较大的临床意义。

The diagnostic value of DBT technique in breast cancer

Objective: To assess the diagnostic value of digital breast tomosynthesis(DBT) combined with full field digital mammography(FFDM) in breast cancer.Methods: The imaging data of FFDM and DBT in 70 patients with breast cancer were retrospectively analyzed.The imaging results of the routine FFDM(craniocaudal position and mediolateral oblique position) were compared with the imaging results of FFDM combined with DBT.The lesions presentation,edge detail and peripheral sign in two groups were recorded,and the lesion was evaluated by mammographic report and BI-RADS.Results: The malignant lesions in 46 cases and bengin lesions in 24 cases were diagnosed using the routine FFDM imaging,and the coincidence rate of which in accordance with the results of pathology was 66%.The malignant lesions in 57 cases and bengin lesions in 13 cases were about diagnosed using the joint examination,and the coincidence rate of which in accordan-ce with the results of pathology was about 81%.The evaluation difference between two methods was statistically significant(P<0.05).Conclusions: DBT can improve the display and diagnosis efficiency of breast lesions,and early diagnosis level of breast cancer,which has good clinical significance.
