摘要
目的评价CT与磁共振成像(MRI)检查及两者联合应用对甲状腺恶性结节的诊断价值。方法回顾性分析50例经病理证实的甲状腺恶性结节患者的CT与MRI资料,分析CT与MRI的表现,比较两者及联合检查对甲状腺恶性结节的诊断符合率。结果 MRI对甲状腺恶性结节的诊断符合率为74%(37/50),CT对甲状腺恶性结节的诊断符合率为58%(29/50),MRI诊断符合率显著高于CT,差异有统计学意义(χ2=5.67,P<0.05)。MRI+CT联合检查的诊断符合率为88%(44/50),显著高于两者单独检查的诊断符合率,差异有统计学意义(χ2=8.03、10.50,P<0.05)。结论 MRI+CT的联合检查能够进一步提高甲状腺恶性结节的检出率,有助于术前做出正确诊断,避免误诊和漏诊。
Objective To evaluate the diagnostic value of CT, MRI and the combination of them in the thyroid malignant tubercles. Methods The CT and MRI data of 50 patients with thyroid malignant tubercles confirmed by pathology were retrospectively analyzed, the manifestations of CT and MRI were observed, and the diagnosis accordance rate was also analyzed. Results The diagnosis accordance rate of MRI to thyroid malignant tubercles was 74% （37/50） ,which was statistically higher than that of CT 58% （29/50） （ X2 = 5.67 ,P 〈 0. 05）. The combination of MRI and CT obtained the diagnosis accordance rate of 88% （44/50） ,which was significantly higher than the single application of MRI or CT （ X2 = 8.03,10.50, P 〈 0.05 ）. Conclusion MRI combined with CT can further improve the detection rate of thyroid malignant tubercles, thus it is helpful to correct diagnosis to avoid misdiagnosis and missed diagnosis.
