目的探讨超声在诊断颈部转移性与淋巴瘤性淋巴结中的应用价值。方法 2007年1月-2008年12月对经病理证实的102例患者120个颈部淋巴结,应用二维超声、能量多普勒显像(PDI)分为两组:转移性淋巴结68个,淋巴瘤性淋巴结52个。对淋巴结长短比(L/S)、结构及血流分布状态进行分析。结果两组淋巴结门消失、局部液化灶、中央血流率比较差异有统计学意义(P<0.05),两组出现淋巴结形态不规则、皮质回声减低、淋巴门型血流、周围型血流率比较差异有统计学意义(P<0.05)。两组的L/S≤2淋巴结无统计学差异(P>0.05)。结论超声检查对颈部转移性淋巴结与淋巴瘤性淋巴结的鉴别诊断有较高价值。
Objective To investigate the value of ultrasound in the diagnosis of cervical metastasis and lymph node lymph nodes. Methods From January 2007 to December 2008, 120 cervical lymph nodes of 102 patients confirmed by pathology were divided into two groups by using two-dimensional ultrasound and energy Doppler imaging (PDI): 68 metastatic lymph nodes, Tumor lymph nodes 52. The ratio of lymph node length to length (L / S), structure and blood flow distribution were analyzed. Results The two groups of lymph nodes disappeared, the local liquefaction stove, central blood flow rate difference was statistically significant (P <0.05), two groups of irregular lymph node morphology, cortical echo decreased, lymphatic portal blood flow, peripheral blood flow rate The difference was statistically significant (P <0.05). Two groups of L / S ≤ 2 lymph node no significant difference (P> 0.05). Conclusion Ultrasonography has high value in the differential diagnosis of cervical lymph node metastasis and lymphoma lymph node.
