摘要
目的探讨甲状腺占位性病变的实时超声弹性成像表现。方法分析158例(211个病灶)甲状腺占位性病变的超声弹性图表现,将图像分为0～Ⅳ级,并与病理结果作对比。结果良性病变组弹性分级80.3%(139/173)为0～Ⅱ级,而恶性病变中86.6%(33/38)为Ⅲ～Ⅳ级。两组病变的弹性分级情况比较差异具显著性意义(P<0.005)。结论不同甲状腺占位性病变的弹性图像具有一些特征性表现。
Objective To evaluate the features of thyroid nodules on real-time elastosonography.Methods The elastograms of thyroid lesions in 158 patients with 211 nodules were analyzed and classified into five grades,with pathologic analysis as the reference standard.Results The elastographic grades of most benign nodules（139/173,80.3%）were 0-Ⅱ,while most of malignancy（33/38,86.6%）were Ⅲ-Ⅳ.The elastographic grades of benign and malignant lesions were of significant difference statistically（P〈0.005）.Conclusion Some typical features of different thyroid lesions on elastosonography are found.
