TI-RADS 3~5级评分法与超声弹性成像分级法对甲状腺良恶性结节诊断价值的对比研究

目的:比较超声TI-RADS评分法与超声弹性成像分级法对甲状腺良恶性结节的诊断价值.方法:分析经病理证实的64例甲状腺结节患者的90枚甲状腺结节,其中良性结节68枚,恶性结节22枚.对90枚结节进行常规超声检查及超声弹性成像检查,将2种方法诊断结果与病理结果进行比较.结果:TI-RADS评分法结果显示的69枚结节为良性,21枚结节为恶性;超声弹性成像结果显示67枚结节为良性,23枚结节为恶性.与病理结果比较,两者的灵敏度、特异度、准确度分别为90.9%、98.5%、96.7%和86.4%、94.1%、92.2%.结论:TI-RADS评分法和弹性成像分级法均是判断甲状腺结节良恶性的有价值的诊断方法.TI-RADS评分法可使超声报告有较客观的统一规范,准确度更高,应用范围更广.

Comparative study of the value between TI-RADS scoring and ultrasound elastography grading in the diagnosis of benign and malignant thyroid nodules

Objective:To compare the value between TI-RADS scoring and ultrasound elastography grading in the diagnosis of benign and malignant thyroid nodules. Methods:Among 90 nodules from 64 patients,the data of 68 benign nodules and 22 malignant nodules identified by pathology were analyzed. The routine ultrasound and ultrasound elasticity imaging of 90 nodules were examined,the results of two examination methods were compared with pathology findings. Results:TI-RADS scoring method showed that 69 nodules were benign,and 21 nodules were malignant. Elastography results showed that 67 nodules were benign, and 23 nodules were malignant. Compared with the pathology results,the sensitivity,specificity,and accuracy of the TI-RADS scoring and elastography were 90. 9%, 98.5% and 96. 7%,and 86. 4%,94. 1% and 92. 2%,respectively. Conclusions:Both TI-RADS scoring method and ultrasound elastography grading method are valuable method to diagnose benign and malignant thyroid nodules. TI-RADS scoring method has more unity of objective standard,higher accuracy and wider application range.
