摘要 目的探讨超声技术在甲状腺结节临床诊断中的应用价值。方法对收治的甲状腺结节患者进行超声检查进行对比分析。结果本组32例患者均经手术病理证实,其中良性者18例(共计55个结节),其中结节性甲状腺肿12例,腺瘤5例,局限性桥本氏病1例;恶性者14例(共计23个结节),其中乳头状癌12例,滤泡癌1例,髓样癌1例。甲状腺恶性结节的超声特征表现为低回声、边界不清、形态不规则、微钙化、高血供、纵横比>1、混合回声及无回声、边界清、形态规则、低血供、纵横比≤1。经统计学分析发现,良性组和恶性组患者在边界、回声类型、周边声晕钙化、纵横比、形态、血供评分等超声特征上比较存在明显差异,且差异具有统计学意义。常规二维和CPD检查为恶性19例,其中与手术病理诊断一致15例;常规二维和CPD检查为良性13例,其中与手术病理诊断一致10例;经统计,常规二维和CPD联合检查的灵敏性为83.33%,特异性为71.43%,准确性为78.13%。结论超声对甲状腺结节的诊断及甲状腺结节良恶性的鉴别具有重要意义。
