彩色多普勒超声TI-RADS分级联合超声弹性对甲状腺癌的诊断价值

Diagnostic value of color Doppler ultrasound TI-RADS classification combined with ultrasound elasticity in thyroid cancer

目的:探讨彩色多普勒超声甲状腺影像学报告及数据系统(thyroid imaging reporting and data system,TI-R ADS)分级联合超声弹性对甲状腺癌的诊断价值。方法:对2018年3月至2021年4月宁国市人民医院收治的102例甲状腺癌患者进行回顾性分析,以细针穿刺活检或手术病理结果作为“金标准”,比较TI-RADS分级、剪切波弹性成像(shear wave elastography,SWE)及二者联合诊断甲状腺良恶性结节的效能,并进一步作受试者工作特征(receiver operating characteristic,ROC)曲线分析。结果:102例患者共有甲状腺结节186个,其中恶性结节115个,良性结节71个。恶性组与良性组TI-RADS分级、SWE参数Ratio值比较,差异有统计学意义(P<0.05)。TI-RADS分级、SWE、二者联合诊断甲状腺良恶性结节的ROC曲线下面积(areas under the curve,AUC)分别为0.794、0.887、0.919,二者联合诊断甲状腺良恶性结节的价值高于SWE和TI-R ADS分级(P<0.05),SWE诊断价值高于TI-RADS分级(P<0.05)。结论:彩色多普勒超声TI-RADS分级与SWE联合可能对甲状腺癌的诊断价值更高。

Objective:To explore the diagnostic value of color Doppler ultrasound thyroid imaging report and data system(TI-RADS)combined with ultrasound elasticity in the diagnosis of thyroid cancer.Methods:A retrospective analysis was conducted on 102 patients with thyroid cancer admitted to Ningguo People’s Hospital from March2018 to April 2021.The results of fine needle biopsy or surgical pathology were used as theagold standardoto compare the TI-RADS grading and shear wave elastography(SWE)and the combined diagnosis of benign and malignant thyroid nodules.The receiver operating characteristic(ROC)curve of the subjects was further analyzed.Results:The surgical pathology results showed that there were 186 thyroid nodules in 102 patients,including 115 malignant nodules and 71 benign nodules.There were significant differences in TI-RADS grade and SWE parameter Ratio between malignant group and benign group(P<0.05).The area under the ROC curve(AUC)of TI-RADS,SWE and combined diagnosis of benign and malignant thyroid nodules were 0.794,0.887 and 0.919,respectively.The value of combined diagnosis of benign and malignant thyroid nodules was higher than that of SWE and TI-RADS(P<0.05),and the value of SWE was higher than that of TI-RADS(P<0.05).Conclusion:Color Doppler ultrasound TI-RADS classification combined with SWE may have higher diagnostic value for thyroid cancer.
