目的:对比研究超声与CT对甲状腺结节良恶性的诊断价值,提高诊断甲状腺结节良恶性的准确率。方法:以我院于2011年1月-2014年12月收治的120例甲状腺结节患者的完整病历资料为分析对象。所有患者在两周内先后进行超声和CT检查,保留有完整的图像检查结果,且术后均经病理学证实。应用超声和CT对甲状腺结节良恶性的诊断价值进行评价。结果:超声联合CT诊断的敏感度、特异度和准确率分别为83.17%、93.06%和92.77%,明显高于超声和CT;误诊率和漏诊率分别为9.03%和15.62%,明显低于超声和CT(P<0.05)。结论:超声应该作为诊断甲状腺结节良恶性的首选方法,但超声和CT诊断各有优缺点,应该联合应用超声和CT对甲状腺结节进行定性,从而提高诊断甲状腺结节良恶性的准确率。
Objective: To compare the diagnostic value of ultrasound and CT in benign and malignant thyroid nodules and improve the accuracy of diagnosis of benign and malignant thyroid nodules. Methods: The data of 120 cases of thyroid nodules in our hospital from January 2011 to December 2014 were analyzed. All patients underwent ultrasound and CT examinations within two weeks, with a complete examination of the images preserved, and pathologically confirmed postoperatively. Application of ultrasound and CT in the diagnosis of benign and malignant thyroid nodules were evaluated. Results: The sensitivity, specificity and accuracy of ultrasonography and CT were 83.17%, 93.06% and 92.77% respectively, which were significantly higher than those of ultrasound and CT. The misdiagnosis rate and misdiagnosis rate were 9.03% and 15.62% respectively, which were significantly lower than those of ultrasound And CT (P <0.05). Conclusion: Ultrasound should be the first choice for the diagnosis of benign and malignant thyroid nodules. However, ultrasound and CT diagnosis have their own advantages and disadvantages. Ultrasound and CT should be used to characterize the thyroid nodules, so as to improve the accuracy of diagnosis of benign and malignant thyroid nodules.
