摘　　要：目的:探讨能谱CT、数据系统分级、超声弹性成像对甲状腺结节性质的鉴别价值。方法:在2020年5月~2022年5月本院收治的甲状腺结节患者中选取72例,对所有患者均进行甲状腺超声检查,并采用数据系统分级、超声弹性成像进行诊断,同时进行颈部CT扫描;最后进行手术病理切片检查,以病理学结果为金标准,对比分析单独诊断与联合诊断的诊断效果。结果:联合诊断的敏感度为96.15%、准确度为93.06%,均高于单独诊断(P<0.05),特异度85.00%联合诊断高于数据系统分级的50.00%(P<0.05),联合诊断与能谱CT、超声弹性成像特异度对比无差异(P>0.05)。恶性结节能谱CT平扫期、动脉期、静脉期的碘含量低于良性结节,超声弹性评分、数据系统分级均高于良性结节(P<0.05)。结论:采用能谱CT、数据系统分级、超声弹性成像联合诊断在良恶性甲状腺结节的鉴别中具有较高的应用价值,相比于单独诊断,联合诊断的准确度与敏感度更高。Objective:To explore the differential value of energy spectrum CT,data system grading,and ultrasound elastography in the nature of thyroid nodules.Methods:72 patients with thyroid nodules admitted to our hospital from May 2020 to May 2022 were selected,and all patients underwent thyroid ultrasound examination.Data system grading and ultrasound elastography were used for diagnosis,and neck CT scanning was also performed;Finally,surgical pathological section examination is performed,and the pathological results are used as the gold standard to compare and analyze the diagnostic effects of individual diagnosis and combined diagnosis.Results:The sensitivity and accuracy of combined diagnosis were 96.15%and 93.06%,both higher than individual diagnosis(P<0.05).The specificity of combined diagnosis was 85.00%,which was higher than the data system classification of 50.00%(P<0.05).There was no difference in the specificity of combined diagnosis compared with energy spectrum CT and ultrasound elastography(P>0.05).The iodine content in the CT plain scan,arterial phase,and venous phase of malignant nodules is lower than that of benign nodules,and the ultrasound elasticity score and data system grading are higher than those of benign nodules(P<0.05).Conclusion:The combined diagnosis of energy spectrum CT,data system grading,and ultrasound elastography has high application value in the differentiation of benign and malignant thyroid nodules.Compared with individual diagnosis,the accuracy and sensitivity of combined diagnosis are higher.
