摘要：

目的 探索浅表转移性淋巴结的彩色多普勒超声成像特征。方法 回顾性分析101例浅表转移性淋巴结的二维灰阶超 声图像及彩色多普勒超声图像特征，评价纵横比、皮髓质形态、砂砾样钙化及血流分布（I-III 级），测量峰值流速及阻力指数。 所有淋巴结性质由穿刺活检后组织病理学确定。结果 64.4%患者表现为皮髓质结构不清，35.6%患者皮质增厚，14.8%内含明显砂砾样化，45.5%纵横比>1。52.5%淋巴结呈I级血流分布，32.7%淋巴结呈II级血流分布，14.9%淋巴结呈III级血流分 布。平均峰值流速为（13.49±6.89）cm/s，平均阻力指数为（0.75±0.11）。结论 彩色多普勒超声成像能够表现浅表转移性淋巴结的血流特征，具有一定的诊断价值。

ABSTRACT: Objective To investigate the characteristics of color doppler ultrasonographic features of superficial metastatic lymphaden. Methods The characteristics of color doppler ultrasonography and two-dimensional grey-scale sonography of 101 patients with superficial metastatic lymphaden were analyzed retrospectively. The aspect ratio, corticomedullary appearance, microcalcification and blood flow distribution (I-III grade) were evaluated. The maximum velocity and resistance index were measured. All the characters of lymphaden were confirmed by pathology after biopsy. Results Among these patients, 64.4% presented unclear corticomedullary structures, 35.6% presented cortex incrassation, 14.8% contained microcalcification and 45.5% had the aspect ratio >1. Among the lymphadens, 52.5% presented blood flow at grade I, 32.7% presented blood flow at grade II and 14.9% presented blood flow at grade III. The average maximum velocity were (13.49±6.89) cm/s and the average of resistance index were (0.75±0.11). Conclusion Color doppler sonography could demonstrate blood flow characteristics of superficial metastatic lymphaden and has certain diagnostic value.
