目的探讨早发性乳腺癌的超声造影声像图特征,评价超声造影对早发性乳腺癌的诊断价值。方法将病理证实的142例乳腺癌患者按照年龄分为两组,A组:≤35岁,51例;B组:>35岁,91例。患者术前均行常规超声及超声造影检查并对声像图特征进行对比分析。结果 A组乳腺癌病灶与B组相比较以病灶大、纵横比小、高回声晕少、内部回声多不均匀、后方衰减少、造影后病灶增大不明显、快进快退、无造影剂滞留为特点,差异具有统计学意义(P<0.05);两组在形态、边界、毛刺征或蟹足征、钙化灶、病灶内部血流丰富程度、增强效果、血管形态、造影剂分布、充盈缺损等方面差异无统计学意义(P>0.05)。结论超声造影检查对早发性乳腺癌诊断具有重要的临床意义。
Objective To investigate the characteristics of echocardiography in early-stage breast cancer and evaluate the diagnostic value of contrast-enhanced ultrasound in early-stage breast cancer. Methods The pathologically confirmed 142 cases of breast cancer patients were divided into two groups according to their age. Group A: ≤35 years and 51 cases; Group B:> 35 years and 91 cases. The patients underwent routine ultrasound and contrast-enhanced ultrasound before operation, and analyzed the features of sonography. Results Compared with group B, the lesions in group A were characterized by large lesions, small aspect ratio, less hypoechoic echo, more nonuniform internal echo and less posterior attenuation. The lesion did not increase obviously after contrast, (P <0.05). The morphology, boundary, burr sign or crab legs syndrome, calcification, the degree of blood flow enhancement, blood vessel morphology, contrast agent distribution, filling There was no significant difference between the two groups (P> 0.05). Conclusion Contrast-enhanced ultrasound is of clinical importance in the diagnosis of early-stage breast cancer.
