Abstract: 【Abstract】〓Objective〓To explore the diagnostic value of shear wave elastography (SWE) in the differential diagnosis of cervical lymph nodes using Receiver Operating Characteristic (ROC) Curve. Methods Totally 76 patients with 120 cervical lymph nodes underwent preoperative conventional ultrasonography and SWE. The differences of SWE quantitative parameters between benign and malignant cervical lymph nodes were compared. The standard of reference was histopathology. ROC curves of SWE quantitative parameters were drawn and the area of under curve was pairwise compared. Results〓The AUCs of elasticity value ratio, mean elasticity value and maximum elasticity value were 0.838, 0.828 and 0.812, respectively. The differences of pairwise comparison of three quantitative parameters had not statistical significance. Conclusion〓All of three SWE quantitative parameters had diagnostic value in the differential diagnosis of cervical lymph nodes. These three quantitative parameters had equal diagnostic performance.
