【摘要】目的：分析超声鉴别诊断甲状腺良、恶性病变的准确性。方法：样本数据选取了在我院接受检查的甲状腺结节患者，并从中抽取了50例，对其分别进行二维超声及彩色多普勒超声诊断，并且将术后病理诊断作为金标准，比较两种超声的诊断准确率、灵敏度及特异度，分析良性及恶性病灶超声的声像图特征及血流参数情况。结果：彩色多普勒超声的准确率、灵敏度以及特异度均高于二维超声，数据比对具有统计学意义(P<0.05)；良性组回声均匀率、形态规则率、边缘清晰率与纵横比<1率均高于恶性组，良性组细小点状钙化率及后方衰减率均低于恶性组，数据比对具有统计学意义(P<0.05)；良性组RI及Vmax低于恶性组，数据比对具有统计学意义(P<0.05)。结论：彩色多普勒超声能够提升鉴别诊断良性及恶性甲状腺病变的准确性，且可提供声像图及血流参数等详细信息，值得临床借鉴与推广。
