TI-RADS评分在甲状腺癌诊断中的应用分析

Diagnostic value of thyroid imaging reporting and data system in thyroid cancer

    摘要
  • 摘要:
      目的  观察甲状腺癌患者超声影像特征, 通过甲状腺影像学报告及数据系统(Thyroid imaging reporting and data sys- tem, TI-RADS)对甲状腺癌性结节进行分级, 期望对甲状腺癌术前定性做出更好预测。
      方法  将2008年9月至2011年8月天津医科大学总医院收治并经病例证实的甲状腺癌患者160例共235枚病灶纳入研究。对所有患者行常规彩色多普勒超声检查观察病灶的大小、数量、外部形态、边界清晰程度及病变肿块、周围血流分布特征, 235个病灶按TI-RADS分级进行评分, 评价TI-RADS评分在甲状腺恶性结节的诊断价值。
      结果  本组病例所示恶性结节176枚, 其中形态欠规则, 边界不清楚144枚(81.8%), 内部不均匀低回声或稍低回声152枚(86.4%), 内部探及沙砾样钙化灶144枚病灶(81.8%)。TI-RADS分级评分4、5级160枚(90.91%), TI-RADS分级评分2、3级16枚(9.09%)。
      结论  甲状腺彩超声像图中出现边界不清, 形态不规则, 低回声或稍低回声肿块, 肿块内探及沙砾样钙化灶, 肿块内部丰富血流信号是诊断甲状腺癌的重要指标, 甲状腺癌病灶结节中TI-RADS分级评分为4、5级者有较高阳性率, 对甲状腺癌术前定性预测有一定意义。

     

    Abstract:
      Objective  To retrospectively characterize and analyze the thyroid ultrasound images of thyroid cancer patients, to classify thyroid nodules according to thyroid imaging reporting and data system (TI-RADS), and to evaluate the diagnostic value of TI-RADS.
      Methods  Clinical data of 160 thyroid cancer patients with 235 nodules from September 2008 to August 2011 were retrospectively analyzed.All patients underwent conventional color Doppler ultrasonography to evaluate the size, number, shape, boundary, and extent of lesions and blood distribution of the nodules.All nodules were analyzed according to TI-RADS classification and scored to evaluate the diagnostic value of TI-RADS.
      Results  Among 176 malignant nodules, 144(81.8%) had lesions showing a mass of irregular boundary with no envelope and halo, 152(86.4%) were inhomogeneous hypoechoic or slightly hypoechoic, or 144(81.8%) exhibited microcalcification.TI-RADS scores of 4 or 5 and 2 or 3 were obtained in 160(90.91%) and 16(9.09%) of the malignant nodules, respectively.
      Conclusion  Thyroid ultrasound sonogram of ill-defined, irregular shape, hypoechoic or slightly hypoechoic mass, microcalcification within the mass, and rich blood flow is an important index for the diagnosis of thyroid cancer.Thyroid nodules with a TI-RADS score 4 or 5 have higher possibility for cancer.Therefore, TI-RADS has a significant diagnostic value for thyroid cancer before operation.
