彩色多普勒超声在滤泡型甲状腺癌和滤泡型甲状腺腺瘤诊断中的临床价值分析

目的 分析彩色多普勒超声诊断滤泡型甲状腺癌(FC)、滤泡型甲状腺腺瘤(FA)的影像特征,并对FC和FA进行鉴别诊断.方法 选取90例行彩色多普勒超声检查的滤泡型甲状腺肿瘤患者作为研究对象,根据彩色多普勒超声检查结果将90例滤泡型甲状腺肿瘤患者分为FC组(n=30)和FA组(n=60),分析两组患者的超声声像图特征,并以病理学检查结果为金标准,评估彩色多普勒超声诊断FC的效能.结果 FC组患者的超声图像多表现为晕环不完整或厚度不均匀、呈低回声、无钙化、结节实性,FA组患者的超声图像多表现为结节形态规则、晕环厚度均匀或薄壁晕环、边界清晰、呈等/高回声、粗大钙化、结节囊性;FC组患者的结节形态不规则、纵横比﹥1、边界不清晰、晕环厚度不均匀或不完整、呈低回声、回声不均匀、无钙化、结节实性、血流模式3~4级所占比例高于FA组(P﹤0.05);彩色多普勒超声诊断FC的灵敏度、特异度、准确度分别为75.00%、89.66%和84.44%.结论 彩色多普勒超声诊断滤泡型甲状腺肿瘤时,FC、FA均具有典型的超声声像图特征,有助于对二者进行鉴别.

Clinical value of Doppler ultrasound in the diagnosis of thyroid follicular cancer and thyroid follicular adenoma

Objective To analyze the imaging features of color Doppler ultrasound in diagnosis of thyroid follicular carcinoma (FC) and thyroid follicular adenoma (FA) so as to make correct diagnosis and differential diagnosis.Method Nighty cases of patients with follicular thyroid tumors underwent Doppler ultrasound examination were selected as the study objects.And they were divided into FC group (30 cases) and FA group (60 cases) according to the results of Dop-pler ultrasound examination.The ultrasonic image features were analyzed in the two groups,and the efficiency of Dop-pler ultrasound in diagnosis of FC was evaluated,taking the pathological results as the gold standard.Result The fea-tures of FC group were characterized by incomplete or irregular halo,hypo-echo,no calcification and solid nodules.The features of FA group were characterized by regular shape,uniform thickness of halo or thin-wall halo,clear boundary,equal/ hyper-echo,bulky calcification and cystic nodules.The proportions of irregular shape,aspect ratio>1,unclear boundary,uneven or incomplete halo thickness,hypo-echo and uneven echo,no calcification,solid nodules and 3-4 level of blood flow in FC group were significantly higher than those in the FA group (P<0.05).The sensitivity,specificity and accuracy of Doppler ultrasound in diagnosis of FC were 75.00%,89.66% and 84.44% respectively.Conclusion For diag-nosis of follicular thyroid tumors by Doppler ultrasound,there are typical imaging features of FC and FA,which is help-ful for differential diagnosis.
