目的 探讨超声与多层螺旋 CT(MSCT)在诊断甲状腺结节钙化中的一 致性与差异性。方法 回顾性分析2014年 10月-2017年10月于我院接受手术治疗的 364例甲状腺结节患者的临床资料。所 有患者于术前行超声、MSCT检查，并于 术后接受病理检查，至少有1项检查结果 提示有钙化存在。比较超声和MSCT对甲 状腺结节钙化的检出率，以及两种检查 结果与术后病理检查结果的一致性，分 析超声和MSCT检测甲状腺结节的图像特 点。结果 超声对乳头状癌、乳头状微癌 等恶性甲状腺结节及良性结节的钙化检 出率均高于MSCT(P﹤0.05)，超声与病理 检查一致性为88.68%(47/53)，高于MSCT 与病理检查的一致性73.58%(39/53)(P﹤ 0.05)。结论 超声诊断甲状腺结节钙化 的准确性高于MSCT，且与病理检查的一 致性更高。

Objective To explore the consistency and difference of ultrasound and multislice spiral CT (MSCT) in the diagnosis of thyroid nodule calcification. Methods The clinical data of 364 cases of patients with thyroid nodules treated with surgery in our hospital from October 2014 to October 2017 were analyzed retrospectively. All patients were given preoperative ultrasound and MSCT examinations, and given postoperative pathological examination, and there was at least 1 test results suggesting the presence of calcification. The detection rates of thyroid nodule calcification by ultrasound and MSCT were compared, and the consistency between the results of the two examinations and the postoperative pathological findings was analyzed, and the imaging features of thyroid nodule by ultrasound and MSCT were analyzed. Results The calcification detection rates of malignant thyroid nodules and benign nodules such as papillary carcinoma and papillary micro-carcinoma by ultrasound were higher than those by MSCT(P<0.05). And the consistency of ultrasound and pathology was 88.68% (47/53), which was higher than that of MSCT and pathology with 73.58% (39/53) (P<0.05). Conclusion The accuracy of ultrasound in the diagnosis of thyroid nodule calcification is higher than that of MSCT, and the consistency is higher in ultrasound and pathology.
