目的探讨彩色多普勒超声在辅助诊断头面部等恶性瘤伴颈淋巴结转移中的作用。方法回顾50例头面部等恶性肿瘤病人的颈部淋巴结触诊、彩色多普勒超声检查和病理诊断资料,用χ2检验进行统计学分析。结果颈部触诊和彩色多普勒超声诊断的敏感性和特异性的比较有显著性差异(χ2=12.48、9.74,P<0.05)。结论彩色多普勒超声诊断颈淋巴结恶性肿瘤转移敏感性较临床触诊高,但特异性较临床触诊低,彩色多普勒超声检查可弥补临床触诊敏感性不高的缺陷。
Objective To explore the role of color Doppler ultrasound in the diagnosis of head and neck malignant tumor with cervical lymph node metastasis. Methods 50 cases of head and neck and other malignant tumor patients with palpation of cervical lymph nodes, color Doppler ultrasound and pathological diagnosis of data, using χ2 test for statistical analysis. Results The sensitivity and specificity of neck palpation and color Doppler ultrasound were significantly different (χ2 = 12.48,9.74, P <0.05). Conclusions The sensitivity of color Doppler ultrasound in the diagnosis of cervical lymph node metastasis is higher than that of clinical palpation, but the specificity is lower than that of clinical palpation. Color Doppler ultrasonography can make up for the low sensitivity of clinical palpation.
