Abstract：Objective: To study the conventional ultrasound and ultrasound elastography in the benign and malignancy applied value in differential diagnosis of cervical lymph nodes. Methords: 84 patients (104 nodules) with cervical lymphadenopathy diagnosed by pathology in our hospital from June 2016 to June 2018 were selected as the research objects. The lymph node vascular pattern was classified by color Doppler ultrasound. Ultrasound elastography was used to analyze the difference of hardness between the lesion area and surrounding tissues. The clinical significance of each index in differentiating benign from malignant cervical lymph nodes was analyzed. The diagnostic results were based on pathological findings, and the diagnostic accuracy of the two methods was compared. Results: Pathological diagnosis showed that 23 (22.12%) of 104 cervical lymph nodes were benign and 81 (77.88%) were malignant; 80 (76.92%) were diagnosed accurately by Doppler ultrasonography; 85 (81.73%) were diagnosed accurately by ultrasound elastography. There was no significant difference between the accuracy of color Doppler ultrasonography and ultrasound elastography. Significance (P>0.05); and pathological diagnosis results were significantly different, P<0.05. Conclusions: Ultrasound elastography has a slightly higher accuracy and sensitivity in the differential diagnosis of benign and malignant cervical lymph nodes, while color Doppler ultrasound has a distinct advantage in specificity, so it can be complementary in the differential diagnosis of superficial lymph nodes.
