Evaluation of Ultrasonography in Diagnosis of Neck Metastatic and Lymphoma Lymph Nodes

Objective To explore the application value of the ultrasound in diagnosis of metastatic and lymphoma lymph nodes of the neck.Methods From January 2007 to December 2008,120 neck lymph nodes of 102 patients confirmed by pathology were divided into two groups,including 68 metastatic lymph nodes and 52 lymphoma lymph nodes.The reports of two groups were performed using two-dimensional ultrasonography and power Doppler imaging (PDI).The long-short axis ratio (L/S),structure,blood flow pattern of lymph nodes were studied.Results The rate of the lymph door disappearance, inner liquefacient position and central blood stream in two groups had statistical difference (P0.05).The rate of irregular form,diminution of cortical resonance,blood stream of lymph door and peripheral flow in two groups had statistical difference (P0.05),but the difference of their L/S ≤ 2 had no statistical significance (P0.05).Conclusion The ultrasonography is a valuable method for diagnosing between neck metastatic nodes and lymphoma lymph nodes.
