Abstract
目的:探讨超声弹性成像(ultrasonic elastography ,UE)和PET/CT检查及两者联合应用对甲状腺癌的诊断价值。方法经手术病理确诊的78例患者92个甲状腺癌结节,回顾性分析其术前 UE和 PET/CT 影像学特征,比较UE和PET/CT 及两者联合应用对甲状腺癌的诊断准确性。结果 UE和 PET/CT 及两者联合诊断准确性分别为85.9%,73.9%,93.5%。UE诊断甲状腺癌的准确性高于PET/CT( P <0.05),两者联合应用的诊断准确性高于UE( P<0.05)或PET/CT单独应用( P =0.000)。结论 UE对甲状腺癌的诊断准确性高于PET/CT ,两者各有优缺点,联合应用对提高甲状腺癌的诊断准确性有较大帮助。
