目的探讨常规超声和超声造影在颈部浅表淋巴结良、恶性诊断中的意义.方法对545例颈部浅表淋巴结病例行常规超声检查(其中52例同期行超声造影检查)及超声引导下穿刺活检,根据病理结果分为良性和恶性淋巴结两组,分析两组常规超声与超声造影的不同特点.结果良性淋巴结组230例,恶性淋巴结组315例.与良性组相比,恶性组的短长径比值(S/L)和结内血流阻力指数(RI)明显高于良性组(P＜0.01).两组间血流类型、超声造影增强模式比较差异有统计学意义(P＜0.01).但造影剂到达时间等差异无统计学意义(P＞0.05).良、恶性淋巴结与颈部大血管的时间强度曲线(TIC)相关性均非常好,且两组间差异无统计学意义(P＞0.05).结论常规超声与超声造影联合运用可以明显提高良、恶性淋巴结的鉴别能力.

Objectlve To investigate the value of basic and contrast-enhanced ultrasound in the diagnosis of superficial cervical lymph nodes.Methods Five hundred and forty-five cases of superficial cervical lymph nodes were sacned by basic ultrasound,in which 52 cases were also scaned by contrast-enhanced ultrasound.All cases were performed ultrasound-guided biopsy.Lymph nodes were divided into benign group and malignant group according to pathology reports.The differences of the two groups were analysed,and statistical analysis was performed.Results Two hundred and thirty cases were benign,315 cases were malignant.S/L(P＜0.01),RI(P＜0.01),vascular pattern(P＜0.01)and contrast enhancement pattern(P＜0.01)between benign and malignant group showed statistical significant differences,while no statistical difference in coefficient correlation of the time-intensity curve between the two groups was found.Conclusions A combination of basic and contrastenhanced ultrasound can significantly enhance the ability to identify malignant lymph nodes from benign lymph nodes.
