【摘要】 目的探讨多层螺旋CT对甲状腺良恶性肿瘤的诊断价值。方法回顾性分析2012年1月~2015年1月我院行多层螺旋CT扫描的甲状腺结节患者共100例患者的临床资料,观察病灶的数目、边缘、密度、有无钙化等。结果入选的100例甲状腺结节患者中术后病理结果证实良性结节76例(84个结节),单侧发病60例,双侧发病16例;其中结节性甲状腺肿60例,甲状腺腺瘤13例,甲状腺炎3例。良性结节多为多发低密度结节,外形规则,实性结节中度强化,边缘可见厚薄不均强化环,结节周围及壁光滑锐利,与周围组织分界清楚。恶性结节24例(26个结节),单侧发病23例,双侧发病1例;其中甲状腺乳头状癌21例,髓样癌1例,滤泡癌1例,甲状腺淋巴瘤1例。恶性结节CT扫描显示边缘多模糊不清、结节形态多不规则、内部细点颗粒状钙化居多。结论多层螺旋CT对甲状腺恶性结节的诊断准确率高,具有重要的诊断价值。更多还原

【Abstract】 Objective To investigate the diagnostic value of multi-slice spiral CT in the diagnosis of benign and malignant thyroid tumors. Methods The clinical data of 100 patients with thyroid nodules who underwent multi-slice spiral CT scanning from January 2012 to January 2015 were retrospectively analyzed. The number, edge, density and calcification of the lesions were observed. Results Selected 100 cases of thyroid nodules in patients with postoperative pathology results confirmed benign nodules in 76 cases(84 nodules), unilateral disease 60 cases, 16 cases of bilateral disease;included 60 cases of nodular goiter, 13 cases of nodular goiter and adenoma, thyroiditis in 3 cases. Benign nodule,multiple nodules of low density, regular shape, nodular moderate enhancement, edge thickness could be found uneven enhanced ring, around the nodules and wall smooth sharp, clear boundaries with the surrounding tissue. Malignant nodules 24 cases(26 nodules), 23 cases of unilateral, bilateral disease in 1 case, in 21 cases of thyroid papillary carcinoma,1 case medullary carcinoma, 1 case follicular carcinoma, 1 case thyroid lymphoma. Malignant nodules on CT scaned showed edge blurred, mostly nodular morphology was irregular, internal punctate calcified granules. Conclusion Multi slice spiral CT has a high diagnostic accuracy, and has important diagnostic value in the diagnosis of thyroid malignant nodules.更多还原
