摘　　要：本文主要探讨甲状腺良恶性结节剪切波弹性成像(SWE)技术参数与超声造影(CEUS)参数相关性及SWE技术、CEUS联合诊断甲状腺良恶性结节的价值。选取甲状腺恶性结节患者51例作为恶性组,甲状腺良性结节患者63例作为良性组,均行SWE、CEUS检查,分析诊断价值,研究结果发现,E_(min)、E_(mean)、E_(max)与Peak呈负相关,与Tp呈正相关(P<0.05);SWE、CEUS联合诊断甲状腺恶性结节的AUC值为0.952,大于任一指标单独诊断(P<0.05);E_(min)、E_(mean)、E_(max)、Tp、MTT与临床分期、结节大小、钙化情况呈正相关,与分化程度呈负相关,Peak与临床分期、结节大小、钙化情况呈负相关,与分化程度呈正相关(P<0.05),这些结果可以证实,SWE技术、CEUS联合诊断甲状腺良恶性结节有较高价值,对指导临床制定治疗方案具有重要作用。The purpose of this study is to explore the correlation between shear wave elastography(SWE)technical parameters and contrast-enhanced ultrasound(CEUS)parameters of benign and malignant thyroid nodules,and the value of combined diagnosis of benign and malignant thyroid nodules by SWE and CEUS.Fifty-one patients with malignant thyroid nodules in our hospital were selected as the malignant group,and 63 patients with benign thyroid nodules were selected as the benign group.All of them underwent SWE and CEUS examinations.The diagnostic value was analyzed.The results of the study found that E_(min),E_(mean),E_(max) and Peak was negatively correlated and positively correlated with Tp(P<0.05);the AUC value of the combined diagnosis of malignant thyroid nodules by SWE and CEUS was 0.952,which was greater than any single index diagnosis(P<0.05);E_(min),E_(mean),E_(max),Tp,MTT is positively correlated with clinical stage,nodule size,and calcification,and negatively correlated with the degree of differentiation.Peak is negatively correlated with clinical stage,nodule size,and calcification,and positively correlated with the degree of differentiation(P<0.05).These results can be It is confirmed that the combination of SWE technology and CEUS in the diagnosis of thyroid benign and malignant nodules is of high value,and plays an important role in guiding clinical development of treatment plans.
