甲状腺癌的螺旋CT诊断

The diagnostic value of SCT in thyroid carcinoma

目的探讨螺旋CT对甲状腺癌的诊断价值。方法对40例手术病理证实为甲状腺癌的患者螺旋CT表现进行回顾性分析。结果40例甲状腺癌中38例表现为低密度区,35例肿瘤密度不均、边界不清,23例肿瘤内出现钙化;其中20例呈细颗粒钙化;增强扫描40例肿瘤呈不均匀强化,其中10例出现瘤周"半岛状"结节,5例出现"强化残圈"征。向周围组织器官浸润19例,颈部淋巴结转移18例,其中6例出现钙化。结论螺旋CT对甲状腺癌的诊断具有重要价值,在评价甲状腺癌向周围组织器官侵犯方面具有明显优势,可为临床制定治疗方案提供重要依据。

Objective To investigate the diagnostic value of spiral computerized tomography （SCT） in thyroid carcinoma. Methods The SCT findings of 40 cases with thyroid carcinoma proved by pathology and surgery were reviewed retrospectively. Results Of the 40 patients with thyroid carcinoma, 38 cases had hypodense lesions, 35 cases showed heterogenous density, with ill - defined and irregular contours and 23 cases were found to have calcifications, including 20 cases with fine globular calcifications. Enhanced SCT revealed that the 40 cases showed heterogenous enhancement. Of these, 10 cases showed peninsular tubercles around the tumor, 5 cases showed no complete enhanced ring around the tumor, 19 cases showed infiltration to the adjacent structures, and 18 cases were revealed metastatic lymphadenopathy in the neck including 6 cases with fine globular calcifications. Conclusion SCT is of significant value in the diagnosis of thyroid carcinoma. It has predominant privilege in assessing the infiltration to the adjacent structures of thyroid carcinoma. SCT scan can provide reliable evidence for clinical therapeutic methods.
