目的 :探讨甲状腺癌和腺瘤的超声表现差异。方法 :甲状腺癌 16例 ,甲状腺瘤 2 3例 ,均经病理证实 ,将其超声表现进行详细对比分析。结果 :二维高频声像图中甲状腺瘤边缘光整 ,有完整的晕环 ,而甲状腺癌边缘欠光整 ,晕环不完整 ,部分结节内可见细小钙化。两者彩色多普勒血流显像(CDFI)均显示血流丰富 ,但甲状腺癌阻力指数 (RI)多大于 0 7,而甲状腺瘤的RI多小于 0 7。结论 :二维高频超声与CDFI对甲状腺癌与甲状腺瘤有鉴别价值。
Objective: To investigate the difference of ultrasound manifestations between thyroid cancer and adenoma. Methods: Thyroid cancer in 16 cases, 23 cases of thyroid tumors, confirmed by pathology, the ultrasound performance of a detailed comparative analysis. Results: In the two-dimensional high-frequency sonography, the margin of thyroid tumor had a complete halo, but the edge of thyroid cancer was less than the whole, the halo was incomplete, and some calcifications were seen in some nodules. Color Doppler flow imaging (CDFI) showed both blood flow rich, but thyroid cancer resistance index (RI) more than 0 7, and thyroid tumor RI less than 0 7. Conclusion: Two-dimensional high-frequency ultrasound and CDFI have the value of differentiating thyroid carcinoma from thyroid adenoma.
