【摘要】 目的 探討超聲在診斷頸部轉移性與淋巴瘤性淋巴結中的應用價值。 方法 2007年1月-2008年12月對經病理證實的102例患者120個頸部淋巴結，應用二維超聲、能量多普勒顯像（PDI）分為兩組:轉移性淋巴結68個，淋巴瘤性淋巴結52個。對淋巴結長短比（L/S）、結構及血流分布狀態進行分析。 結果 兩組淋巴結門消失、局部液化灶、中央血流率比較差異有統計學意義（Plt;0.05），兩組出現淋巴結形態不規則、皮質回聲減低、淋巴門型血流、周圍型血流率比較差異有統計學意義（Plt;0.05）。兩組的L/S≤2淋巴結無統計學差異（Pgt;0.05）。 結論 超聲檢查對頸部轉移性淋巴結與淋巴瘤性淋巴結的鑒別診斷有較高價值。【Abstract】 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 (Plt;0.05). The rate of irregular form, diminution of cortical resonance, blood stream of lymph door and peripheral flow in two groups had statistical difference (Plt;0.05), but the difference of their L/S≤2 had no statistical significance (Pgt;0.05). Conclusion The ultrasonography is a valuable method for diagnosing between neck metastatic nodes and lymphoma lymph nodes.
