甲状腺癌结节二维超声特征与超声弹性指数比值及超声造影定量参数与颈部淋巴结转移之间关系分析

摘要

ObjectiveThe relationship between the two-dimensional ultrasound characteristics of thyroid nodules and the index of ultrasound elasticity, the quantitative parameters of contrast-enhanced ultrasound, and lymph node metastasis in the neck.Methods 80 patients diagnosed as thyroid cancer and treated were selected.The two-dimensional ultrasound features and the ratio of ultrasound elasticity index and the quantitative parameters of contrast-enhanced ultrasound were detected.The relationship between them and cervical lymph nodes was recorded and analyzed.ResultsAmong the two-dimensional ultrasound features, the difference between the echogenic texture and calcification types and the metastasis of lymph nodes in cancer nodules was statistically significant (P＜0.05);the difference in the ratio of the ultrasonic elasticity index of cancer nodules in lymph node metastasis and lymph node metastasis was not significant.There was a statistically significant difference (P＜0.05);the PI of contrast-enhanced ultrasound parameters was statistically significant in lymph node metastasis and lymph node metastasis (P＜0.05).That is the occurrence of lymph node metastasis was related to the peak intensity of the nodules of the tumor.ConclusionThe ratio of two-dimensional ultrasound features and ultrasound elasticity index and the quantitative parameters of contrast-enhanced ultrasound can help to detect the lymph node metastasis in the lateral neck region of the patient before operation, which has certain reference significance for the clinical treatment plan.%目的 探讨甲状腺癌结节二维超声特征与超声弹性指数比值及超声造影定量参数与颈部淋巴结转移之间关系.方法 选取确诊为甲状腺癌并接受治疗的患者80例, 分别对患者进行二维超声特征与超声弹性指数比值及超声造影定量参数的检测, 记录并分析其与颈部淋巴结的关系.结果 二维超声特征中, 癌结节内部回声质地和钙化类型间的差异与淋巴结的转移具有统计学意义 (P＜0.05);癌结节超声弹性指数比值在有淋巴结转移和无淋巴结转移中的差异具有统计学意义 (P＜0.05);超声造影定量参数中PI在有淋巴结转移和无淋巴结转移中的差异具有统计学意义 (P＜0.05), 即淋巴结转移的发生与癌结节造影峰值强度有关.结论 二维超声特征与超声弹性指数比值及超声造影定量参数可以很好帮助在术前检测患者的侧颈区有无淋巴结的转移, 对临床确定治疗方案有一定的参考意义.
