Two-dimensional Medulla, Three-dimensional Blood Flow And Elastography Of The Cervical Lymph Nodes To Explore The Value Of Differential Diagnosis

Objective:To study the two-dimensional medulla, three-dimensional blood flow and elasticity imaging to differential diagnose the benign and malignant cervical lymph nodes of the clinical application value. Methods:73cases of100patients with superficial lymph nodes respectively took two-dimensional gray-scale sonography ultrasound.3D color doppler energy (3D-CDE) and elastography (UE) check. All the lymph nodes then confirmed by pathological biopsy and divided into benign group (lymphoid tuberculosis, lymph adenitis and hyperplasia of reactivity lymph nodes) and malignant group (lymphoma and metastatic lymph nodes) by follow-up. We observed the two-dimensional medulla shape, three-dimensional blood flow distribution model and elasticity figure that reflect the organization hardness, then evaluated these three techniques for cervical lymph nodes in the diagnosis of benign and malignant differential efficiency ultrasonic ultrasonographic characteristics and analyze the two groups. Results:The sensitivity, specificity and accuracy of100cervical lymph nodes by the diagnosis of B ultrasound,3D-CDE and UE joint (parallel) were87.9%,71.4%,8i.0%;94.8%,85.7%,91.0%;89.7%,83.3%,87.0%; The sensitivity specificity and accuracy of three methods joint (parallel) in the diagnosis of cervical lymph nodes were96.6%,66.7%,77.0%; The characteristics of three kinds of inspection technology in the diagnosis of cervical lymph nodes were statistically significant (P<0.05):The ultrasound manifestations and pathological match degree of Kappa were0.592.0.893.0.707respectively. Conclusion: Three-dimensional flow organization has the best diagnosis effect and good clinical use. Elastography hardness classification identify benign and malignant lesions has important value and better than the two dimensional in some ways.
