高频超声对甲状腺囊实性结节良恶性鉴别的效果

目的 探讨高频超声对甲状腺囊实性结节良恶性鉴别的效果.方法 选取甲状腺囊实性恶性结节患者47例以及甲状腺囊实性良性结节患者47例.所有患者均予以高频超声检查,观察对比良、恶性结节图像特征.结果 高频超声诊断恶性结节的误诊率为8.51％(4/47),高于病理诊断的0.00％(0/47),差异有统计学意义(P<0.05).良性结节高频超声的病灶内部结构、内部回声、边界、形状、钙化与恶性结节对比,差异有统计学意义(P均<0.05).良性结节RI值<0.7人数占比为85.11％(40/47),高于恶性结节的14.89％(7/47),差异有统计学意义(P<0.05).结论 高频超声诊断甲状腺囊实性良性结节的准确度高,有利于鉴别甲状腺囊实性结节良恶性.

High Frequency Ultrasonography in the Differentiation of Benign and Malignant Thyroid Cystic Nodules

Objective To study the high frequency ultrasound in the differentiation of benign and malignant thyroid cystic nodules.Methods 47 patients with malignant thyroid cystic nodules and 47 patients with benign thyroid cystic nodules were selected.All patients received high frequency ultrasound,benign and malignant nodules observed contrast image characteristics.Results The high frequency ultrasound diagnosis of malignant nodules the misdiagnosis rate was 8.51％(4/47),higher than that of pathological diagnosis 0.00％(0/47),there had statistically significant difference(P<0.05).Benign nodule lesions internal structure of high frequency ultrasound,internal echo and boundary,shape,calcification and malignant nodules compared,the difference was statistically significant(P<0.05).Number of benign nodules RI values<0.7 85.11％(40/47),higher than that of malignant nodules 14.89％(7/47),the difference was statistically significant(P<0.05).Conclusion High frequency ultrasound diagnosis of thyroid cystic nodules has high accuracy,is conducive to differentiate benign and malignant thyroid cystic nodules.
