Abstract

The aim of this study was to evaluate the diagnostic performance of quantitative shear wave velocity (SWV) measurement on acoustic radiation force impulse (ARFI) elastography for differentiation between benign and malignant thyroid nodules using meta-analysis. The databases of PubMed and the Web of Science were searched. Studies published in English on assessment of the sensitivity and specificity of ARFI elastography for the differentiation of thyroid nodules were collected. The quantitative measurement of ARFI elastography was evaluated by SWV (m/s). Meta-Disc Version 1.4 software was used to describe and calculate the sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, diagnostic odds ratio and summary receiver operating characteristic curves. We analyzed a total of 13 studies, which included 1,854 thyroid nodules (including 1,339 benign nodules and 515 malignant nodules) from 1,641 patients. The summary sensitivity and specificity for differential diagnosis between benign and malignant thyroid nodules by SWV were 0.81 (95% confidence interval [CI]: 0.77-0.84) and 0.84 (95% CI: 0.81-0.86), respectively. The pooled positive and negative likelihood ratios were 5.21 (95% CI: 3.56-7.62) and 0.23 (95% CI: 0.17-0.32), respectively. The pooled diagnostic odds ratio was 27.53 (95% CI: 14.58-52.01), and the area under the summary receiver operating characteristic curve was 0.91 (Q* = 0.84). In conclusion, SWV measurement on ARFI elastography has high sensitivity and specificity for differential diagnosis between benign and malignant thyroid nodules and can be used in combination with conventional ultrasound.

摘要

本研究旨在通过荟萃分析评估定量剪切波速度(SWV)测量在声辐射力脉冲(ARFI)弹性成像中对甲状腺良恶性结节鉴别的诊断性能。检索了PubMed和科学网数据库。收集了以英文发表的关于ARFI弹性成像鉴别甲状腺结节敏感性和特异性评估的研究。通过SWV(米/秒)对ARFI弹性成像的定量测量进行评估。使用Meta-Disc 1.4版软件描述并计算敏感性、特异性、阳性似然比、阴性似然比、诊断比值比以及总结接收器操作特征曲线。我们共分析了13项研究,这些研究包括来自1641例患者的1854个甲状腺结节(包括1339个良性结节和515个恶性结节)。通过SWV鉴别甲状腺良恶性结节的总结敏感性和特异性分别为0.81(95%置信区间[CI]:0.77 - 0.84)和0.84(95%CI:0.81 - 0.86)。合并的阳性和阴性似然比分别为5.21(95%CI:3.56 - 7.62)和0.23(95%CI:0.17 - 0.32)。合并的诊断比值比为27.53(95%CI:14.58 - 52.01),总结接收器操作特征曲线下面积为0.91(Q* = 0.84)。总之,ARFI弹性成像中的SWV测量对甲状腺良恶性结节的鉴别诊断具有高敏感性和特异性,可与传统超声联合使用。
