目的 探讨常规超声及弹性成像二者联合应用对甲状腺癌的诊断价值.方法 我院行甲状腺癌手术的患者52例,共93个结节,所有患者术前均行常规及弹性成像超声检查,术后经病理证实.诊断甲状腺癌常规超声和弹性成像的准确性、特异性及敏感性.结果 常规超声诊断甲状腺癌的敏感性75.86%,特异性84.38%,准确性81.72%;而超声弹性成像诊断甲状腺癌的敏感性89.66%、特异性85.94%、准确性87.10%;常规超声联合超声弹性成像诊断甲状腺癌的敏感性93.10%、特异性90.62%、准确性91.40%.同常规超声诊断相比,二者联合应用对甲状腺良、恶性结节诊断的差异有统计学意义,P＜0.01.结论 常规超声联合超声弹性成像应用可提高诊断甲状腺癌的准确性,可为临床诊断提供重要信息.%Objective To evaluate the clinical value of ultrasongraphy and elastography in diagnosis of thyroid nodules . Methods Fifty two patients with 93 thyroid nodules were examined by both conventional ultrassonography and elastography . Using the pathological diagnosis as the gold standard , the sensitivity, specificity, and accuracy of conventional ultrasound imaging and elastogra -phy were evaluated in thyroid cancer . Results The sensitivity, specificity, and accuracy of conventional ultrasound imaging in the di — agnosis of thyroid carcinoma were 75. 86% , 84. 38% , and 81. 72% respectively, those of elastography imaging were 89. 66% , 85. 94% , and 87. 10% respectively , and those of ultrasonography combined with elastography imaging in diagnosis of thyroid carcino -ma were 93. 10% , 90.62% , and 91.40% , respectively. There was significant difference between the two methods in diagnosis of thy — roid carcinoma (P <0.01). Conclusions Conventional ultrasound imaging combined with elastography imaging raises the accuracy in diagnosis of thyroid carcinoma.
