【摘要】：目的:探讨剪切波弹性成像(SWE)诊断结果为假阴性和假阳性甲状腺结节的二维超声及SWE特点,以提高诊断准确率。方法:选择我院就诊的189例甲状腺结节患者,共189个结节,均经手术及病理证实。记录每例患者结节的二维超声成像特点、SWE特点及术后病理结果,比较分析SWE检测为假性和真性结节的二维成像特点。结果:术后病理显示189个结节中,良性结节74个(39.2%),恶性结节115个(60.8%)。常规超声诊断甲状腺恶性结节的敏感性为56.5%、特异性为81.1%;SWE诊断甲状腺恶性结节的敏感性为60.9%、特异性为85.1%。SWE诊断良性结节的假阳性率和恶性结节的假阴性率分别为14.9%和39.1%,假阴性率高于假阳性率。纵横比1和直径偏小(0.5cm)均与SWE的误诊显著相关(P0.01)。结论:SWE在鉴别甲状腺结节的良恶性中具有重要意义,但也存在漏诊或误诊,临床医生基于SWE作出诊断时,应仔细评估其二维超声特点及其他检查结果。
[Abstract]:Objective: to investigate the characteristics of two dimensional ultrasound and SWE in diagnosis of false negative and false positive thyroid nodules with shear wave elastography. Methods: 189 thyroid nodules were selected from 189 patients in our hospital. All cases were proved by operation and pathology. The characteristics of 2-D ultrasound imaging and the pathological results of each patient were recorded. The features of two-dimensional imaging of false and true nodules detected by SWE were compared and analyzed. Results: the pathological findings of 189 nodules were observed after operation. The sensitivity of conventional ultrasound in the diagnosis of thyroid malignant nodules was 56.5, the specificity was 81.1. The sensitivity of SWE in the diagnosis of thyroid malignant nodules was 60.9 and the specificity was 85.1. SWE was the false positive rate of benign nodules. The false negative rates of malignant nodules were 14.9% and 39.1, respectively. The false negative rate was higher than the false positive rate. The aspect ratio 1 and the diameter of 0.5 cm were significantly correlated with the misdiagnosis of SWE. However, there are also missed diagnosis or misdiagnosis. When clinicians make a diagnosis based on SWE, they should carefully evaluate the characteristics of two-dimensional ultrasound and other findings.
