| 中文摘要:目的 探讨灰阶超声联合精细血流显像（fine flow）和弹性成像在评估乳腺癌腋窝淋巴结转移中的诊断价值。方法 选取乳腺癌患者的148枚同侧腋窝淋巴结，手术前分别用灰阶超声观察图像特征、测量皮质厚度及长短径，并计算纵横比（L/S）；精细血流显像观察其血供分布类型；弹性成像对其行弹性评分。并与术后病理结果对比分析。结果 灰阶超声显示转移性腋窝淋巴结L/S值≤2.0，皮质厚度≥0.3cm，甚至淋巴门消失，与非转移性淋巴结比较差异有统计学意义（P<0.05）。精细血流显像显示淋巴结的血供分布非转移性以Ⅰ型、Ⅱ型为主，转移性以Ⅲ型、Ⅳ型为主，差异有统计学意义（P<0.05）。弹性成像检查非转移性淋巴结弹性分值以1、2分为主，转移性淋巴结弹性分值以3、4分为主，差异有统计学意义（P<0.05）。3种检查方式联合使用诊断准确度较任意单一检查方式均提高，差异有统计学意义（P<0.05）。结论 灰阶超声、精细血流显像和弹性成像技术3种检查方式联合应用明显提高了超声对乳腺癌腋窝淋巴结转移诊断的准确性。 |

| Abstract:Objective To explore the value of fine blood flow imaging (fine flow) combination elastography in the diagnosis of axillary lymph node metastasis of breast cancer on the basis of gray-scale ultrasonography. Methods Totally 148 ipsilateral axillary lymph nodes from patients with breast cancer were selected before operation.We observed scale image feature, measured the cortical thickness and diameter, and calculated the aspect ratio (long diameter/short diameter ratio, L/S) of the axillary lymph nodes by gray-scale ultrasonography. We observed blood distribution type of these lymph nodes by fine blood flow imaging, maked a elastic score for these lymph nodes by elastography. They were analyzed and compared with the postoperative pathological results. Results Gray-scale ultrasonography indicated image characteristics of those axillary lymph nodes:the ratio of L/S ≤ 2.0; thecortical thickness ≥ 0.3cm, even the hilum of lymph gland disappeared. There was a significant difference between the metastatic axillary lymph nodes and non-metastatic axillary lymph nodes (P<0.05). Fine blood flow imaging showed that the blood distribution type of non-metastatic axillary lymph nodes were mainly type Ⅰ or type Ⅱ, but the blood distribution type of metastatic axillary lymph nodes were mainly type Ⅲ or type Ⅳ. There was a significant difference between the two groups (P<0.05). Elastography showed the elastic score of non-metastatic axillary lymph nodes was mainly 1 or 2 points, but the elastic score of metastatic axillary lymph nodes was mainly 3 or 4 points. The accuracy of combined use was higher than one technology. There was a significant difference between the two groups (P<0.05). Conclusion The combined use of the Gray-scale ultrasonography, fine blood flow imaging and elastography significantly improved the accuracy of ultrasound in the diagnosis of axillary lymph node metastasis of breast cancer. |
