能谱CT在甲状腺良恶性结节中的鉴别价值分析

Differential value of energy spectrum CT in benign and malignant thyroid nodules

目的探讨能谱CT在甲状腺良恶性结节中的鉴别诊断价值。方法选取我院2015年1月至2016年7月收治的85例甲状腺结节的患者为研究对象,分为良性组和恶性组,另选取40例甲状腺的正常腺体为正常组,以上患者均行颈部能谱CT平扫及动态增强扫描。比较三组的碘浓度、能谱曲线斜率。结果恶性组在平扫期、动脉期、静脉期的碘浓度小于良性组,良性组小于正常组,均有统计学意义(P<0.05)。恶性组平扫期、动脉期、静脉期的能谱曲线斜率低于良性组,良性组低于正常组,均有统计学意义(P<0.05)。结论能谱CT在鉴别甲状腺良恶性肿瘤中具有较高的应用价值,值得推广。

Objective To investigate the value of CT in differential diagnosis of benign thyroid nodules. Methods 85 cases of thyroid nodule patients in our hospital from August 2015 to 2016 January were as the research object,they were divided into benign and malignant groups,another 40 cases of normal thyroid patients were as the normal group,above patients were all underwent neck energy spectrum CT plain scan and enhanced scan. The concentration of iodine and the slope of the energy spectrum curve of the three groups were compared. Results The iodine concentration in the plain scan,arterial phase and venous phase in the malignant group was less than that in the benign group and the positive group was less than that in the normal group,the difference was statistically significant（ P 0. 05）. In the malignant group,the slope of the phase,arterial phase and venous phase was lower than that of the benign group,and the positive group was lower than the normal group,the difference was statistically significant（ P 0. 05）. Conclusion Energy spectrum CT can be used in the differential diagnosis of benign and malignant thyroid tumors,and it is worth popularizing.
