摘要
目的探讨甲状腺良恶性结节的声像图特点及其诊断价值。方法回顾分析我院有病理结果的患者80例,且均来我科行超声检查。结果 80例甲状腺结节患者,共计106个结节,其中良性结节56个、恶性50个。本组50个恶性结节中31个为低回声结节、28个无包膜回声、11个有微钙化及纵横比>1的11个;56个良性结节中低回声结节11个、9个无包膜、3个见微钙化及无一例纵横比>1;上述声像图特征恶性结节发生率明显高于良性结节(P<0.05),差异均有统计学意义。106个结节误诊13个,误诊率9%(5/56),灵敏度84%(42/50)、特异度91%(51/56)、漏诊率16%(8/50)。结论对于低回声结节伴有微钙化、无包膜、纵横比大于1等多种超声特征同时出现时,可提高超声鉴别甲状腺良恶性结节的诊断准确性。
Objective To investigate the ultrasonographic characteristics of benign and malignant thyroid nodules and it＇ s diagnostic value. Methods Retrospectively analyze 80 case of patients with pathological results in our hospital, who underwent ultrasound in our department. Results Eighty case of patients with thyroid nodules, a total of 106 nodules,of which 56 benign nodules and 50 malignant. Of 50 malignant nodules, 31 were low echo nodules,28 were non enveloped, 11 with slight calcification, and 11 aspect ratios were greater than 1. However, 11 of the 56 benign nodules had low echo nodules, 9 were free of capsule, 3 of them showed slight calcification, and none of them had an aspect ratio greater than 1. The incidence of malignant nodules were significantly higher than that of benign nodules, and the differences were statistically significant（P〈0.05）. Of 106 nodules,there were 13 misdiagnosed,the misdiagnosis rate was 9%（5/56）, the sensitivity of 84%（42/50）, the specificity of 91%（51/56）, and the rate of missed diagnosis was 16%（8/50）. Conclusion For the low echo nodules with micro calcification, no capsule, aspect ratio greater than 1, and a variety of ultrasound features at the same time, it can improve the accuracy of ultrasound diag-nosis of benign and malignant thyroid nodules.
