目的分析对比CT与MRI诊断甲状腺结节的临床意义。方法分别对99例患者进行CT与MRI检查,共检出109个结节,所有结节都被病理证实,分析两种检查手段的敏感性、特异性以及准确率。结果 CT鉴别诊断甲状腺结节的灵敏性显著优于MRI(P<0.05)。MRI鉴别诊断甲状腺结节的特异性及准确性均优于CT,但差异不存在统计学意义(P>0.05)。结论 CT与MRI可以很好的鉴别诊断甲状腺结节的良恶性,且各有所长,两者联合使用能够很好的加强准确性。
Objective To analyze the clinical significance of CT and MRI in the diagnosis of thyroid nodules. Methods Ninety-nine patients were examined by CT and MRI respectively. A total of 109 nodules were detected. All nodules were confirmed by pathology. The sensitivity, specificity and accuracy of the two methods were analyzed. Results The sensitivity of CT in differential diagnosis of thyroid nodules was significantly better than that of MRI (P <0.05). The specificity and accuracy of MRI in the diagnosis of thyroid nodules were better than that of CT, but the difference was not statistically significant (P> 0.05). Conclusion CT and MRI can be a good differential diagnosis of benign and malignant thyroid nodules, and their own strengths, a combination of the two can well enhance the accuracy.
