甲状腺癌的多层螺旋CT后处理技术及诊断价值探讨

目的:探讨甲状腺癌的多层螺旋CT(MSCT)后处理方法及评价其诊断价值。方法:对甲状腺肿瘤患者行MSCT平扫、增强及三维后处理,回顾性分析16例经手术及病理证实的甲状腺癌患者的术前MSCT表现。结果:所有病例MSCT均可见肿块,14例密度不均,8例肿瘤内出现钙化,12例呈形态不规则,13例肿块边缘模糊不清,6例瘤内呈“半岛状”瘤结节,5例瘤周呈“强化残圈”征,10例肿瘤侵犯周围组织器官,9例出现颈部淋巴结转移。结论:甲状腺癌的MSCT表现具有一定特征性,MSCT能较准确地判断甲状腺癌有无侵犯周围组织器官,为临床制定治疗方案提供重要依据。

Discusion of Post-Processing Technique with Multi-Slice Spiral CT in Diagnosis of Thyroid Carcinoma

Objective To explore and evaluate the value of post-processing technique with multi-slice spiral CT(MSCT) in the diagnosis of thyroid carcinoma.Methods Thyroid neoplasms patients underwent plain and contrast enhancement with MSCT. The images were processed with 3-D technique.The manitestion with MSCT of 16 cases of thyroid carcinoma confirmed by operation and pathological results were retrospectively analysed.Results All the 16 patients demonstrated detectable masses on the MSCT images. 14 cases showed heterogeneous density, 8 cases were detected calcifications in tumor,12cases showed irregular shape,13 cases showed untidy margin,6 cases showed peninsluar tubercles in the tumor,5 cases showed no complete enhaced ring around the tumor, 10 cases infiltrated the adjacent structures and 9 cases were revealed metastatic lymphadenopathy on the neck.Conclusion Some characteristic manifestation of thyroid carcinoma can be observed on MSCT.It can correctely evaluate the adjacent structures invasion by thyroid carcinoma and provide reliable information in selecting therapeutic methods.
