三维超声成像对乳腺癌外科手术的指导价值

 目的 探讨三维超声成像对乳腺癌外科手术的指导意义。方法 对68例经病理证实的乳腺癌患者，手术前用二维及三维超声观察乳腺肿瘤情况。结果 三维超声成像不仅能提高乳腺癌的超声诊断符合率符合率94.1 %，高于二维（88.2 %）]，还可以清晰显示乳腺癌肿块形态结构及其与周边临近组织的立体关系及浸润层次等，如肿瘤侵犯皮肤、胸肌、胸壁等情况（显示率分别为75.0 %，63.6 %，60.0 %），且对乳腺癌肿内血流分布及走行情况显示更清晰、敏感（显示率达95.6 %）。结论 三维超声成像能更充分地表现肿瘤的形态结构、毗邻关系及血流分布情况, 对乳腺癌外科手术有着重要的指导意义。

The clinical value of three-dimensional ultrasonography for breast cancer operation

Objective To evaluate the clinical value of three-dimensional ultrasonography(3DUS) for breast cancer operation. Methods Sixty-eight patients with breast cancer were examined with two-dimensional ultrasonography(2DUS) and three-dimensional ultrasonography before operation. Results 3DUS not only improved the rate of sonography's diagnosis for breast cancer(88.2 % for two-dimension, 94.1 % for three-dimension), but also clearly showed patterns of breast lumps with the neighboring structure and the adjacent three-dimensional relations and the level of violations, such as the skin, chest muscle, chest wall, etc(the display rate is 75.0 %, 63.6 % and 60.0 % respectively). And it displayed the blood stream distribution in the mass of breast tumor more clearly and sensitively (95.6%). Conclusions 3DUS demonstrated the tumor's configuration, relations and the blood stream distribution. It had great significance in the operation for breast cancer.
