摘　　要：目的探讨超声与螺旋CT对甲状腺腺瘤的诊断效力。方法选择41例甲状腺腺瘤及52例甲状腺癌患者为研究对象,均接受螺旋CT检查,观察螺旋CT对甲状腺腺瘤及甲状腺癌的诊断效力。包括诊断灵敏度、特异度、阳性预测率、阴性预测率、正确率及诊断符合率。结果甲状腺腺瘤及甲状腺癌在边缘中断、病灶数量、增强后边缘模糊、瘤体边缘不规则、细颗粒样钙化及囊变方面,差异具有统计学意义(P<0.05)。以病理结果为标准,螺旋CT共正确诊断甲状腺腺瘤51例,甲状腺癌42例,其诊断敏感性90.4%、特异性90.2%、阳性预测率92.2%、阴性预测率88.1%、正确率80.6%及诊断符合率90.3%。结论在甲状腺腺瘤的的定性诊断中,螺旋CT诊断效力高,适合临床广泛应用。Objective To investigate the effect of ultrasound and spiral CT in the diagnosis of thyroid adenoma. Methods 41 cases of thyroid adenoma and 52 cases of thyroid cancer were selected as the research object, Underwent spiral CT examination, To observe the effect of spiral CT in diagnosis of thyroid adenoma and thyroid carcinoma. Including the diagnostic sensitivity, specificity, positive predictive rate, negative predictive rate, correct rate and diagnostic accuracy. Results Thyroid adenoma and thyroid carcinoma were statistically significant（P〈0.05） in the aspects of edge disruption, the number of lesions, the enhancement of the edge of the tumor, the irregular edge of the tumor, the calcification of the fine particles and the change of the capsule. To the pathological results as the standard, spiral CT was correctly diagnosed 51 cases of thyroid adenoma, 42 cases of thyroid cancer, The diagnostic sensitivity was 90.4%, specificity 90.2%, positive predictive rate of 92.2%, negative predictive rate of 88.1%, correct rate of 80.6% and diagnostic accuracy of 90.3%. Conclusion In the qualitative diagnosis of thyroid adenoma, spiral CT is effective and suitable for clinical application.
