高频超声检查对浅表淋巴结良恶性病变的诊断价值

目的：探讨高频超声检查在浅表淋巴结良恶性鉴别诊断中的应用价值。方法对128例浅表淋巴结患者进行高频超声检查，鉴别患者淋巴结的良恶性，并与术后的病理检查结果进行比较。结果高频超声对浅表淋巴结良恶性鉴别诊断准确率90．5％，误诊20例。良性淋巴结的长径和短径值分别为（2．2±0.8）cm、（1．0±0．4）cm，恶性淋巴结长径和短径值分别为（3．4±1．0）cm、（1．7±0．9）cm，恶性组数值均显著大于良性组（t＝9．13、5．11，均P＜0．05）。恶性组RI为（0．44±0．06），良性组RI为（0．83±0．23），两组差异有统计学意义（t＝5．06，P＜0．05）。结论高频超声检查在淋巴结节良恶性诊断中具有很好的应用价值，结合淋巴结内部血流及形态等特征进行综合分析，能够有效减少误诊和漏诊的发生。

The clinical value of the high-frequency ultrasound in the diagnosis of enlarged superficial lymph nodes

Objective To analyze the clinical value of the high frequency ultrasound in the enlarged superfi-cial lymph nodes diagnosis.Methods The enlarged superficial lymph nodes features and clinical data of 128 cases of enlarged superficial lymph nodes patients was studied in our hospital.Results The coincidence rate of the high-fre-quency ultrasound in the diagnosis of enlarged superficial lymph nodes was 90.5%.There were 20 cases misdiag-nosed.The long and short diameter of lymph nodes in the benign group were （2.2 ±0.8）cm,（1.0 ±0.4）cm.The long and short diameter of lymph nodes in the malignant group were （3.4 ±1.0）cm,（1.7 ±0.9）cm.The two groups had significant difference （t=9.13,5.11,all P 〈0.05）.The RI of the malignant group and benign group were （0.44 ±0.06） and （0.83 ±0.23）,respectively.The two groups had significant difference （t=5.06,P〈0.05）. Conclusion The high-frequency ultrasound has a high application value in the diagnosis of lymph nodes.It could effectively reduce the misdiagnosis and miss diagnosis in combination with characteristics of nodular internal blood flow and nodular morphology characteristics.
