甲状腺乳头状癌多层螺旋CT诊断与影像分析

Analysis of multislice CT in papillary thyroid carcinoma diagnosis and image

目的通过对有完整资料的患者颈部甲状腺CT平扫及增强扫描后的影像分析,有助于提高CT对甲状腺乳头状癌诊断的检出率,减少误诊,为临床提供最佳的治疗方案。方法对59例病理证实的有完整临床资料的甲状腺乳头状癌多层螺旋CT(MSCT)征象进行分析、总结、整理。结果 59例甲状腺乳头状癌,有63个乳头状癌性灶。病灶包膜破损的有39个,占62%。镶嵌征有23个,占36%。钙化有18个,占29%,其中粗钙化(除砂砾样钙化外)有12个,占总钙化灶67%。结论甲状腺MSCT征象中,病灶包膜破损、镶嵌征、钙化(特别是大钙化),对甲状腺乳头状癌诊断有重要价值。

Objective The patients with complete data have neck thyroid scan and enhanced CT scan image analyzed,finding out the value of CT signs,the value in the diagnosis of thyroid papillary carcinoma and to reduce misdiagnosis,providing the best treatment.Methods In 59 cases with complete clinical data of thyroid papillary carcinoma multislice CT（MSCT） appearances were analyzed,summarized,arranged.Results Fifty-nine cases of thyroid papillary carcinoma were with 63 papillary cancer foci.There were 39 lesion envelope broken,accounted for62%.There were 23 mosaic sign,accounted for 36%.There were 18 calcification,accounting for 29%,among them large calcification（except for sandy calcification） has 12,accounting for the total calcification in 67%.Conclusion The MSCT signs of lesions of thyroid,coating damage,mosaic sign,calcification（especially large calcification）,has important value for the diagnosis of thyroid papillary carcinoma.
