摘要
目的:探讨甲状腺影像报告和数据系统(Thyroid Imaging Reporting and Data System,TI-RADS)分级对诊断甲状腺癌中的应用价值。方法:选择甲状腺结节患者75例并进行外科手术或细针穿刺活检(fine needle aspiration,FNA),应用高频彩色多普勒超声对双侧甲状腺进行扫查。根据TI-RADS对甲状腺结节分级,选择TI-RADS 3~5级的患者63例(81个病灶),将甲状腺TI-RADS分级情况与病理切片结果进行比较和分析,评估TI-RADS分级对鉴别甲状腺癌的效能。结果:在63例患者(81个病灶)中,病理学活检结果显示,28个TI-RADS 3级病灶中,良性23个(82.14%)、恶性5个(17.86%);32个TI-RADS 4级病灶中,良性5个(15.63%)、恶性27个(84.37%);21个TI-RADS 5级病灶中,良性0个(0)、恶性21个(100%)。TI-RADS分级诊断甲状腺癌的灵敏度和特异度分别为88.67%和82.14%。TI-RADS 3~5级病灶的纵横比边缘、边界、钙化、血管充盈、血流阻力指数(resistance index,RI)值差异均有统计学意义(P<0.01)。结论:TI-RADS分级诊断甲状腺癌的灵敏度和特异度较高。在高频超声检查甲状腺中,应用TI-RADS分级对诊断甲状腺癌具有重要临床意义。
Objective: To study the role of Thyroid Imaging Reporting and Data System(TI-RADS) category in ultrasonic diagnosis of thyroid cancer. Methods: A total of 75 patients with thyroid diseases who underwent surgery or fine needle aspiration(FNA) were selected. All the patients underwent thyroid examination with high-frequency color Doppler ultrasonography. According to TI-RADS category, 63 patients(81 thyroid lesions) with TI-RADS grade 3-5 were recruited. The characteristics of highfrequency color Doppler ultrasonography in diagnosis of thyroid lesions with different TI-RADS grades were compared with the histopathological results. Then the efficacy of TI-RADS category in the identification of thyroid cancer was assessed. Results: In all 63 patients(81 thyroid lesions) confirmed by histopathology, 28 lesions were TI-RADS grade 3, in which 23(82.14%) were benign, 5(17.86%) were malignant; 32 lesions were TI-RADS grade 4, and histopathology confirmed 5(15.63%) were benign, 27(84.37%) were malignant; 21 lesions were TI-RADS grade 5, and all the lesions were malignant confirmed by histopathology(100%). The sensitivity and specificity were 88.67% and 82.14% respectively in the diagnosis of thyroid cancer by TI-RADS category. Statistical differences were found among thyroid lesions with TI-RADS grades 3, 4, 5 in A/T, margin, boundary, calcification, vascularity and blood flow and resistance index(RI). Conclusion: The sensitivity and specificity of TI-RADS category are high in diagnosing thyroid cancer by high-frequency color Doppler ultrasound.
