螺旋CT对甲状腺疾病的诊断及鉴别价值研究

目的探索16排螺旋CT对甲状腺疾病的诊断及鉴别价值研究。方法回顾性分析我院2013年1月至2014年1月乳甲外科经手术、实验室检查确诊为甲状腺疾病的患者42例,收集42例患者的影像学资料及临床资料,整合CT诊断结果与手术活检结果对比,分析其不同类型甲状腺疾病诊断符合率与讨论鉴别不同类型甲状腺疾病。结果 42例患者CT结果与病理活检结果比较,诊断符合率为95.23%(40/42),CT对恶性疾病诊断符合率为91.66%(11/12),对良性疾病诊断符合率为96.66%(29/30)。可从包膜是否完整、病灶形态、是否与周围组织分界清楚等为鉴别良、恶性甲状腺疾病,恶性甲状腺疾病CT图像特点为边缘不清、形态不规则且伴有微小钙化点、无包膜等。结论16排MSCT对甲状腺疾病病变情况显示清楚,对不同甲状腺疾病的诊断符合率高;诊断医生需掌握不同类型甲状腺疾病的特点,对不同甲状腺疾病进行诊断、鉴别诊断具有重要意义。

Diagnose and Identification Value Study of Slice Spiral CT on Thyroid Disease

Objective To investigate the diagnose and identification value of 16-slice spiral CT on thyroid disease.Methods 42 cases with thyroid disease diagnosed by surgery and laboratry inspection in our hospital from January 2013 to January 2014 were selected.Their clinic data were selected,compare diagnostic coincidence rate of differeht types of thyroid disease and different types of thyroid disease.Results Compare the CT results and biopsy of 42 cases,diagnostic coincidence rate was 95.23％(40/42),diagnostic coincidence rate of CT on malignancy was 91.66％(11/12)and on benign disease was 96.66％(29/30).Benign and malignant thyroid can be diagnosed by diolame is complete or not,focus form,peripheral tissues well-defined or not.CT image features of malignant thyroid:nuclear ledge irrgular shape,tiny calcified points and nonencapsulated.Conclusion 16-slice spiral CTcan showthyroid disease changes clearly and has higher diagnostic coincidence rate of different types of thyroid disease.Doctors should know features of different types of thyroid disease,it has important significance on diagnose and identification.
