高频超声在甲状腺良恶性肿块鉴别诊断中的应用价值

The value of different ultrasound images of thyroid tumor for distinguishing benign and malignant tumor

目的探讨甲状腺肿瘤的不同超声图像特征对鉴别良恶性的价值。方法回顾性总结113例经手术病理结果证实的甲状腺肿瘤的超声资料,分析各超声图像特征与良恶性的相关性。结果甲状腺肿瘤声像图中,病灶边缘、钙化、内部回声及血流表现与病变的良恶性关系密切,边缘不清者恶性占48.1%,有小钙化灶者恶性占52.9%,血流条状者恶性占30.6%;边缘清晰者良性占86%,无钙化、粗大钙化或边缘钙化者良性占85%,血流点状者良性占84.4%。结论超声图像特征对甲状腺良恶性病变的判定具有一定意义。

Objective To study the value of different ultrasound images of thyroid tumor characteristics for distinguish benign and malignant tumor. Methods 113 patients with thyroid tumor were pathologically confirmed in our hospital from January 2008 to January 2009, whose ultrasound image features of thyroid were analyzed for correlation with benign and malignant. Results Of thyroid ultra-sonography, the lesion edge, calcification and internal echo and flow were closely related with benign and malignant. Unclear edge,48.1% were malignant tumors. Small calcification, 52.9% were malignant. Blood Strips, 30.6% were malignant. Sharp edges, 86% were benign. Without calcification, calcification, or the edge of coarse calcification, 85% were benign. Blood spots, 84.4% were benign. Conclusion Ultrasound image characteristics has a certain significance for distinguishing between benign and malignant thyroid tumor.
