1、高频超声对健康体检人群中甲状腺微小癌的筛查作用研究【摘要】目的探讨高频超声对甲状腺微小癌(TMC)的筛查诊断价值。方法选取108例经过手术或穿刺病理证实的甲状腺微小癌患者(甲状腺微小癌组),以同期最常见、最易混淆的108例结节性甲状腺肿小结节患者(甲状腺肿小结节组)作为对照,对两组进行高频二维超声筛查,对比总结两组的筛查结果。结果甲状腺微小癌组在形态不规则、周围无回声、甲状腺边缘中断、内部低回声、边界不清晰、微钙化灶、无声晕、无囊性变、纵横比(A/T)>1方面的血流分布比例高于甲状腺肿小结�组,差异有统计学意义(P0.05)。甲状腺微小癌组患者的血流收缩期峰值
2、流速(PSV)为(45.49±8.29)cm/s,中国6/vie 阻力指数(RI)为(0.69±0.16),明显高于甲状腺肿小结节组的(35.44±8.14)cm/s、(0.52±0.14),差异具有统计学意义(P1及微钙化,血流丰富程度,瘤体周围及颈部多发淋巴结有助于甲状腺微小癌的诊断,高频超声对甲状腺微小癌具有重要的筛查作用,综合分析二维及彩色多普勒超声图像特点,可提高甲状腺微小癌检出率。 【关键词】高频超声;健康体检人群;甲状腺微小癌 DOI:10.14163/j.ki.11-5547/r.2017.08.007 【Abstract】Object
