Value Of Ratio Of Medulla And Blood Flow Type Of Cervical Lymph Node In Evaluation Lesions

Objective: The value of2D and3D ultrasound parameter in lesions of the cervicallymph nodes. Methods: Totally131patients with169cervical lymph node wereenrolled. Patients were divided into3groups:（Reactive node group, lymphoma group andmetastatic node group）, according to their pathologic or Follow-up results.Its shortdiameter and length ratio （S/L）, lymph node medulla area and the total area ratio （Am/At）,lymph node medulla volume and total volume ratio （Vm/Vt） and three-dimensional bloodflow distribution type were analyzed, and discriminant function were established. Results:①three-dimensional blood flow distribution type had statistical difference among3groups（all P＜0.05）.②Vm/Vt for the variables X₁, three-dimensional blood flowdistribution type for the variable X₂, S/L for the variable X₃, Am/At for the variable X₄, Y₁,Y₂, Y₃represent reactive node group, lymphoma group and metastatic node group,3Fisher discriminant functions were: Y₁=-1.532+1.389X₁+1.806X₂+0.995X₃+1.236X₄,Y₂=-11.392+11.932X₁+7.530X₂+3.989X₃+2.002X₄, Y₃=-15.531+12.377X₁+7.850X₂+7.344X₃+3.422X₄.③And their accuracy rate of retrospective inspection were85.00%（51/60）,66.67%（38/57）,90.38%（47/52）, respectively. Conclusion: Three-dimensionl blood flow distribution type and Vm/Vt could be used as index in diagnosis ofcervical lymph nodes with different lesion properties．...
