摘要
目的：探讨高频彩色多普勒超声对甲状腺结节内钙化灶的诊断价值。方法根据病理结果回顾分析85例甲状腺良恶性结节病例的声像图特征，重点观察结节内有无钙化及钙化的大小、形态及分布情况，将钙化灶分为粗大钙化和微小钙化。结果85例甲状腺结节患者中，良性病变55例，超声检出甲状腺结节合并钙化7例（12．73％），其中粗大钙化6例（10．91％），微小钙化1例（1．82％）；恶性结节30例，合并钙化22例（73．33％），其中粗大钙化3例（10．0％），微小钙化19例（63．33％）。恶性结节总钙化率、微小钙化率明显高于良性结节的发生率，粗大钙化率基本相似。结论超声检出微小钙化对诊断甲状腺癌具有较高的特异性，鉴别甲状腺良恶性结节可以依据结节内钙化回声特点做出诊断。
Abstract
Objective To explore the value of high-frequency color Doppler ultrasonography in the diagnosis of thyroid nodule calcification .Methods According to the results of pathology retrospectively ultrasonographic characteristics analysis of 85 cases of benign and malignant thyroid nodules,observation was focused on the size, shape and distribution of nodules with no calcification and calcification.The calcification,divided into coarse calcifications and microcalcification.Result In 85 cases of thyroid nodules,55 cases of benign lesions,ultrasonography in diagnosis of thyroid nodules with calcification in 7 cases(12.73%),including 6 cases of coarse calcifica-tions(10.91%),1 cases of microcalcifications(1.82%);30 cases with malignant nodules with calcification,22 cases(73.33%),including 3 cases of coarse calcifica-tions(10%),19 an example of microcalcifications(63.33%).The total rate of malignant nodules of calcification,microcalcification were significantly higher than that in benign nodules occur rate,coarse calcification was similar.Conclusion Ultrasonic detection of microcalcifications with high specificity for the diagnosis of thyroid cancer , differential diagnosis of benign and malignant thyroid nodules can make a diagnosis based on the echo characteristics of calcifications .
