| 目的 探讨超声显像在甲状腺多发结节中鉴别癌结节的价值。方法 对术后病理证实的83例甲状腺癌合并良性结节患者的超声表现进行研究分析。结果 83例甲状腺癌中,恶性结节89个。甲状腺多发结节中良、恶性结节的二维征象纵横比≥1,实性低回声、边缘模糊、微钙化的检出及后方回声衰减等方面具差异有统计学意义(P＜0.01),同时恶性结节内Ⅱ级、Ⅲ级血流显示较良性结节差异亦有统计学意义(P＜0.01)。89个癌结节中,直径≤1 cm的微小甲状腺癌结节占52.81%(47/89),超声对癌结节的诊断符合率达67.42%(60/89)。结论 以下几个主要特征有助于在甲状腺多发结节中鉴别癌结节:圆形或类圆形、实性低回声、边缘模糊、微钙化、后方回声衰减及内部血供丰富;尤其不能忽视微小甲状腺癌存在的可能。 |

| Objective To probe the value of ultrasound in detection of malignant foci among multiple thyroid nodules. Methods Ultrasonograms of 83 patients with pathologically confirmed thyroid cancer combined with benign nodules were analyzed. Results Among 83 patients of thyroid carcinoma, 89 malignant and 87 benign nodules were detected with ultrasound. Significant differences of two-dimensional ultrasounic signs including low echoes, border fuzzy, micro-calcification and rear echo attenuation were found bteween malignant and benign nodules (P<0.01). There were significant differences in the grade Ⅱ, Ⅲ blood flow between malignant and benign ones (P<0.01). Of 89 malignant nodules, small thyroid carcinoma with diameter ≤1 cm accounted for 52.81% (47/89), and ultrasound diagnostic rate of all cancer nodules was 67.42% (60/89). Conclusion Ultrasounic characteristics including low echoes, border fuzzy, micro-calcification, rear echo attenuation and internal rich blood flow contribute to differentiate the thyroid microcarcinoma from multinodules.In particular, the microcarcinoma should not be ignored. |
