【摘要】 目的:探讨甲状腺肿块的超声声像图特征,以提高超声诊断的正确率。方法:采用东芝240A型超声诊断仪,探头频率7.5MHz,对436例甲状腺肿块及颈两侧进行常规扫描检查分析并与病理结果进行对照分析。结果:436例甲状腺肿块,与病理结果对照,总体超声诊断符合率为92.2%402/436;其中腺瘤超声诊断符合率为96.7%208/215,结节性甲状腺肿为90.2%185/205;甲状腺癌为56.3%9/16。结论:超声对腺瘤及结节性甲状腺肿有较高的诊断价值,而对甲状腺癌因良性、恶性肿块的并存及微小癌早期缺乏恶性图像特征,其超声诊断正确率较低,必要时还需结合其它影像检查或细针穿刺检查。更多还原

【Abstract】 Objective：To improve ultrasonic diagnostic rate of thyroid adenoma ．Meth ods：The thyroid and the front neck were scanne d by TOSHIBA２４０A ultrasonic diagnosis system with a probe of７．５MHz frequen cy in４３６cases of thyroid mass and were compared to pathology．Results：On com paring to pathology，the ul trasonic diagnosis accordance rate wa s９２．２％（ ４０２／４３６）in pa－tients with thyroid adenoma，９６．７％（２０８／２１５） in adenoma，９０．２％（１８５／２０５）in nodular goiter and５６．３％（９／１ ６）in thyroid can cer．Con clu sion：The clinical di agnostic value of ul traso nography is more important in adenoma and nodular goiter and less in thyroid c an cer．Other image examination or fine needle biopsy are needed for mixed benig n and malignaut tumor of the thyroid and for micro－carcinoma．更多还原
