Abstract:
Objective To explore the relationship between the features of thyroid carcinoma and its metas tasis to cervical lymph nodes(MCLN) with conventional and contrast-enhanced ultrasound imaging.Methods Totally 89 thyroid carcinoma nodules were used in this study.The pathology of those samples was confirmed by surgical pathology at the First Affiliated Hospital of Shanxi Medical University from Sep 1,2014 to Oct 30,2015.The samples were divided into two groups based on the surgical pathology report:the group with MCLN (49) and the group without MCLN (40).Using the pathology report as gold standard,we analyzed the conventional ultra sound features,contrast-enhanced ultrasound enhancement pattern as well as the quantitative parameters.Results ① There was statistically significant difference in tumor size,contact of the tumor with capsule or not,microcalcification of the tumor,as well as echo texture of the thyroid carcinoma nodules between the groups (P＜0.05).②) There was statistically significant difference in peak intensity (PI) between the two groups (P＜0.05).Conclusion There is a positive correlation between cervical lymph nodes metastasis and tumor size,with or without contact with fibrous capsule,with or without microcalcification,the internal echo as well as PI.
