高频超声探测甲状腺微钙化的临床意义

Clinical value of high-frequency ultrasound in the diagnosis of micro-calcifications

目的评价高频超声探测甲状腺疾病微钙化在诊断病变性质的临床意义。方法 145例甲状腺疾病患者发现钙化306处。术前患者均进行甲状腺高频超声检查,重点观察甲状腺内有无钙化。结果甲状腺癌病人微小钙化的发生率明显高于良性甲状腺疾病的发生率,差异有统计学意义P<0.05。微小钙化对于甲状腺微小乳头状癌更有统计学意义。结论微钙化的存在增加了恶变的可能,应用高频超声探测甲状腺微钙化具有重要临床诊断价值。

Objective The aim of this prospective study was to evaluate the significance of sonographically detected thyroid calcification in the diagnosis of micro-calcifications.Methods 145 patients with thyroid disease,including 306 with thyroid calcifications were studied.Each patient underwent preoperative,High-frequency ultrasound to evaluate the thyroid gland for the presence of calcification.Result The incidence of calcification and micro-calcification in the tubercle of thyroid gland for patients with thyroid cancer was significantly higher than that of patients with benign thyroid gland diseases（P ＆lt; 0.05）.Microcalciffcation had statistical significanc.Conclusion Thyroid nodules with calcification especially micro-calcifications was considered to be the most specific sign of thyroid carcinoma,so the detection of it should be an important diagnostic criterion.
