CT评价甲状腺钙化的临床意义

目的：探讨用CT评估甲状腺钙化对诊断甲状腺癌的意义。方法：回顾同期284例病理证实的各类甲状腺疾病患者的术前CT资料，分析甲状腺钙化与甲状腺癌的关系。结果：患者术前CT检出钙化66例（23．9％）。良性疾病钙化率为20．1％．恶性疾病钙化率为47．5％，两者比较差异有显著性（P=0.000）。钙化灶的大小与甲状腺癌无显著性关系，而微钙化的多少与甲状腺癌差异有显著性（P=0.000）。结论：CT对钙化，特别是多灶微钙化的检出对甲状腺癌的诊断有重要意义，是甲状腺癌的一个特征性征象。

Clinical value of CT detection for calcification in thyroid nodules

Objective:To investigate the significance of thyroid calcification in the diagnosis of thyroid carcinoma. Methods:The CT imaging of 284 patients with variant thyroid diseases proved by pathology were reverwed for the presence of calcification,and the correlation between calcification and thyroid carcinoma was analyzed. Results:The total thyroid calcification ratio in CT imaging was 23.9%,which in benign samples was lower than that in malignant samples.There was significant correlation between the number of micro-calcification and thyroid carcinoma,but not between the size of calcification and thyroid carcinoma. Conclusion:Thyroid nodules with calcification especially a number of micro-calcification is considered to be vary valuable in the diagnosis of thyroid carcinoma.
