| 目的 探讨数字化乳腺点压摄影对致密型乳腺的乳腺癌的诊断价值。 方法 对68例致密型乳腺的乳腺癌患者经全数字化乳腺X线检查常规检查(首尾位及内外斜位)后,对触诊异常区域加摄无放大点压摄影,分别分析常规摄影和点压摄影的影像表现并进行对比。 结果 点压摄影在肿块显示、毛刺显示方面明显优于常规摄影。两种方法对钙化的显示率无显著差别,但在显示钙化数量、大小、形态及密度等具体特征方面,压点摄影优于常规摄影。4例常规摄影显示乳腺结构扭曲的患者,点压摄影可见小肿块;5例常规摄影显示乳腺局灶性不对称患者,点压摄影均可见肿块。点压摄影的诊断准确率(86.76%)高于常规摄影(63.24%),漏诊及误诊率(4.41%)低于常规摄影(14.70%)。 结论 常规乳腺摄影结合点压摄影能够明显提高致密型乳腺的乳腺癌的诊断准确率。 |

| Objective To observe the diagnostic value of digital spot mammography for breast cancer in dense breasts. Methods Sixty-eight patients with breast cancer in dense breasts proved pathologicaly were enrolled. After conventional digital mammography (including craniocaudal view and midiolateral oblique view) were conducted for every patient, digital spot mammography without magnification were performed in the suspected area. The image findings of both digital spot mammography and conventional mammography were analyzed and compared. Results Digital spot mammography was superior to conventional mammography in showing the margin and spiculated features of masses. There was no significant difference in showing calcification of tumors, whereas digital spot mammography was superior to conventional mammography in showing the specific features of calcification like quantity, size, shape and density. Masses were found with digital spot mammography in 4 cases of architectural distortion and 5 cases of focal asymmetric density on conventional mammography. The accuracy of digital spot mammography was higher than that of conventional mammography (86.76% vs 63.24%), and the misdiagnosis of digital spot mammography was lower than that of conventional mammography (4.41% vs 14.70%). Conclusion Combination of conventional mammography with spot mammography can improve the diagnostic accuracy and reduce the misdiagnosis of brast cancer in dense breasts. |
