摘　　要：目的探讨超声图像中甲状腺结节的钙化灶的大小及分布类型对良恶性结节鉴别的临床意义。方法收集超声检查甲状腺结节内有钙化灶的50例手术患者,术前行超声检查并记录钙化的大小和分布类型;将钙化的直径d>1 mm定义为粗钙化,d≤1 mm定义为微钙化;根据术后病理结果,进行统计对照,探讨对良恶性鉴别的价值。结果 50例存在钙化的甲状腺结节中,其中良性18例,恶性32例,在钙化大小方面,当钙化d≤1 mm时,检出恶性结节的特异度(72.2%)及阳性预测值(83.8%)。钙化分布方面,边缘型钙化多见于良性结节(77.2%),中央型钙化多见于恶性结节(92.8%)。结论钙化对鉴别结节良恶性具有重要意义,不同大小和分布类型的钙化,其鉴别诊断价值也不同。Objective To study the ultrasonic images of thyroid nodule calcifications in size and distribution types of benign and malignant identify clinical significance. Methods Collect ultrasound of thyroid nodules with calcifications of 50 patients with surgery. A regular ultrasound examination was carried out before surgery, during the examination,the size and distribution type of calcification in thyroid nodules were recorded; The calcification of diameter d〉 1 mm defined as coarse calcification, d ≤ 1 mm defined as microcalcification; Postoperative pathological results, according to the statistical comparison, to discuss the value of the identification of benign and malignant. Results 50 cases of thyroid nodules of calcification,18 cases of benign and malignant 32 cases,in terms of size of calcification, when calcified d ≤ 1 mm, check out the specific degree of malignant nodules（72.2%） and positive predictive value（83.8%）. Distribution of calcification, borderline calcification seen in benign nodules（77.2%）,the central type calcification seen in malignant nodules（92.8%）. Conclusion Calcification is of great significance to differentiate benign and malignant nodules, different size and distribution of calcification, the differential diagnosis value is also different.
