螺旋CT对甲状腺肿瘤的诊断与鉴别价值

Diagnosis and Differential Diagnosis of Spiral CT to Thyroid Tumor

目的:探讨螺旋CT检查对甲状腺良恶性肿瘤的诊断和鉴别价值。方法:回顾性分析2008年1月～2011年4月我院收治的30例甲状腺肿瘤患者,对其术前CT检查诊疗资料和术后病理组织诊断资料进行对比,分析两者的一致性。结果:本组30例甲状腺肿瘤患者中,术前CT诊断出16例患者为甲状腺癌、14例患者为甲状腺良性肿瘤,该诊断结果和术后病理组织诊断的符合率分别为94.1%和92.9%。CT图像上出现甲状腺边缘不规则、肿瘤周边呈现半岛样结节、瘤周呈现不完整包膜样低密度影、细沙样钙化,均是恶性甲状腺肿瘤的特征性表现。结论:甲状腺肿瘤患者采用螺旋CT扫描进行检查诊断,可以较准确地区分其良恶性,尤其对甲状腺癌的诊断非常准确,且CT检查还可清楚显示出肿瘤对周围组织的侵犯情况以及肿瘤转移情况对治疗方案的制定提供关键的指导。

Objective：To evaluate spiral CT examination in the diagnosis of thyroid tumors and differential values Methods：A retrospective analysis from January 2008 to April 2011 in our hospital,30 cases of thyroid cancer patients,their preoperative and postoperative CT examination pathological diagnosis and treatment diagnostic information to make comparisons,analyze their consistency. Results：The group of 30 cases of thyroid cancer patients,preoperative CT in 16 patients diagnosed with thyroid cancer.thyroid benign tumors in 14 patients.tbe diagnosis and postoperative pathologic diagnosis was consistent with rates of 94.1%and 92.9%.Appears on CT images of thyroid irregular margin.tumor-like nodules around the present peninsula,showing incomplete peritumoral capsule-like low density,sand-like calcification are characteristic of malignant thyroid tumors performance.Conclusion：rhyroid cancer patients using spiral CT scan for diagnosis.can be more accurately distinguish between the benign and malignant,particularly in the diagnosis of thyroid cancer is very accurate,and CT examination also clearly showed the tumor to the surrounding tissue and tumor metastasis violations,the development of treatment programs provide critical guidance.
