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.
