目的:探讨早期乳腺癌的超声影像学特征,评价超声对早期乳腺癌的诊断价值。方法:130例经病理证实的乳腺小肿块(直径≤2cm)患者按肿块恶良性分为乳腺癌组(53例)和良性病变组(77例),对比两组患者术前肿块的二维声像学特征和多普勒超声血流特点。结果:乳腺癌组中多见形状不规则、边界不清、沙粒样钙化、蟹足征、后方回声减弱等现象,且与良性病变组比较,差异有统计学意义(P<0.05);两组肿瘤的彩色多普勒超声血流情况比较,差异有统计学意义(P<0.05);两组患者中,阻力指数>0.7的例数比较差异有统计学意义(P<0.05)。结论:超声诊断技术在早期乳腺癌的诊断中具有重要的应用价值,结合其他临床诊断方式,将大大提升早期乳腺癌的确诊率。
Objective: To investigate the characteristics of ultrasound imaging in early stage breast cancer and evaluate the diagnostic value of ultrasound in early stage breast cancer. Methods: One hundred and thirteen patients with pathologically confirmed small breast masses (≤2 cm in diameter) were divided into breast cancer group (n = 53) and benign lesion group (n = 77) according to malignant tumor mass. Like features and Doppler ultrasound flow characteristics. Results: In the breast cancer group, there were more irregular shapes, unclear boundary, calcification of calcification, signs of crab patella, and weakened echoes of the back. Compared with the benign lesions group, the difference was statistically significant (P <0.05); The difference of color Doppler flow between the two groups was statistically significant (P <0.05). There was significant difference between the two groups in the number of resistance index> 0.7 (P <0.05). Conclusion: Ultrasound diagnosis has an important value in the diagnosis of early breast cancer. Combined with other clinical diagnosis methods, the diagnosis rate of early breast cancer will be greatly improved.
