摘要
目的：本研究旨在分析甲状腺乳头癌的平扫及增强CT的各种征象,提高CT诊断能力。方法：回顾性分析我院2010年1月~2010年6月期间经手术病理证实的甲状腺乳头癌43例,术前均行甲状腺CT薄层（2~5mm）平扫及动态增强扫描。分析CT影像特点及其病理学基础。结果：43例甲状腺乳头癌病例中,边界不清32例（32/43,75%）;钙化31例（31/43,74%）（其中沙粒样钙化19例（19/43,61.3%）,斑片状10例（10/43,23%）,爆米花样2例（2/43,5%）;密度不均匀36例（36/43,84%）;岛样强化13例（13/43,30%）,39例（39/43,90%）动脉期明显强化,静脉期CT值降低;甲状腺双叶多发11例（11/43,25.6%）,并发结节性甲状腺肿25例（25/43,56%）;合并颈部淋巴结转移9例（9/43,21%）。结论：甲状腺CT平扫中的沙粒样钙化,CT扫描的强化特征,对甲状腺乳头癌诊断有一定的临床价值。
Objective：The aim of this research was to analyze various signs of papillary thyroid carcinoma in CT plain and enhancement,and to improve the diagnostic ability.Methods：43 patients with papillary thyriod carcinoma,proven by operation and pathology,were retrospectively analyzed in our hospital from January to June 2010.All cases were examined by CT plain（slice thickness 2～5 mm） and enhancement scans before operation.We analyzed CT images and its pathology.Results：All 43 cases with papillary thyriod carcinoma： 32 cases ill defined boundary（32/43,75%）;31 calification（31/43,74%）（among these,19 the sand-like calcification（19/43,61.3%）,10 patchy calcification（10/43,23%）,2 popcorn calcification（2/43,5%）;36 heterogeneous density（36/43,84%）;13 insula enhancement（13/43,30%）,39 cases artery time obvious enhancement（39/43,90%）,which CT value in venous phase decline more than 20HU;11 cases with double-sided（11/43,25.6%）,25 cases with nodular goiter（25/43,56%）;9 cases with cervical lymph node metastasis（9/43,21%）.Conclusion：It is helpful to the diagnosis of papillary thyroid carcinoma through analyzing CT images,including the sand-like calcification in plain scan and CT enhance features.
