全数字化X线摄影在早期乳腺癌诊断中的价值

目的:探讨全数字化乳腺X线摄影(full-field digital mammography,FFDM)对早期乳腺癌诊断价值。方法:收集经手术及病理证实的早期乳腺癌58例,术前均采用FFDM检查,常规采用头尾位、内外斜位,必要时加照侧位及局部点片。结果:58例X线显示肿块38例,恶性钙化26例,结构扭曲8例,局灶致密影4例,"导管征"5例,血管增粗15例。FFDM对早期乳腺癌诊断的符合率为87.9%。结论:FFDM能清晰显示乳房各个层次及乳腺癌的直接和间接征象,对早期乳腺癌具有重要的诊断价值。

Role of full-field digital mammography in diagnosis of early breast cancer

Objective：To study the value of full-field digital mammography（FFDM） in diagnosing early breast carcinoma. Methods： Fifty-eight cases of breast cancer confirmed by surgery and pathology were collected in the study. All the cases had been examined by FFDM before surgery. Craniocaudal view and midiolateral oblique view were conducted, and midiolateral view or spot view was employed when necessary. Results：Lumps were detected in 38 cases, malignant calcification was noticed in 26 cases, focal architecture distortion in 8 cases, small focus of increased density in 4 cases,＂ ductal sign＂ in 5 cases and distended blood vessel in 15 cases. The diagnosis rate was 87.9% by FFDM. Conclusions：FFDM can clearly demonstrate each layer of the breast, as well as the direct and indirect signs of breast carcinoma, which is of great value in diagnosis of early breast carcinoma.
