| 目的 评价超声弹性图像、面积及弹性比值在甲状腺良恶性结节中的特征。
方法 回顾性分析105例甲状腺结节超声弹性图像特征，测量蓝色面积及弹性比值。恶性结节分为A组（最大径<1cm）和B组（最大径≥1cm）。
结果 47/70例恶性结节呈（蓝色）团块状，19/35良性结节呈点状 (P<0.05)；恶性与良性结节弹性比值分别为1.70±0.67 和1.32±0.39(P<0.05)，面积比值分别为44.8±22.35%和33.63±20.10%(P<0.05)。面积比值在A、B两组间具有明显差异（P<0.05）。
结论 超声弹性图像特征及面积、弹性比值能够表现甲状腺良恶性结节不同特征。 |

| Abstract: |
| Objective: to assess images characteristics, area ratio and elasticity ratio in thyroid nodules. Methods: Image characteristics, elastic area ratio, elasticity ratio of 105 nodules scanned via elastosonography were assessed retrospectively. The malignant nodules were divided into two groups: group A with maximum diameter less than 1cm and group B with maximum diameter more than or equal to 1cm. Results: 47 of the 70 malignant nodules presented mass-like and 19 of 35 benign nodules were assessed as dot-like. The elasticity ratio of malignant and benign nodules were 1.70±0.67 and 1.32±0.39 (P<0.05), respectively. The elastic area ratio of malignant and benign nodules were 44.8±22.35% and 33.63±20.10% (P<0.05), respectively. For elastic area ratio, there were significant difference between A group and B group (P<0.05). Conclusions: Images characteristics, area ratio and elasticity ratio contributed to displaying different characteristics of thyroid malignant and benign nodules. |
