Ultrasound (US) is a valid and reliable imaging tool for evaluation of joint and tendon inflammation as well as cartilage and erosions in patients with rheumatoid arthritis (RA). Synovitis is usually scored semiquantitatively for both gray scale synovitis and power Doppler activity, and use of an atlas for US scoring has shown excellent reliability. Several scores are shown to be responsive to medical treatment, but the optimal joint/tendon score is to be explored. Doppler activity may be quantified by use of pixel counts and flow may be examined by use of resistive index. US-guided injections are better tolerated and have increased efficacy, as compared with palpation guidance, and should thus be included in rheumatologic practice. Different methods such as three-dimensional US, contrast-enhanced US and fusion imaging methods are all possible US approaches that may be used in treatment of RA patients in the future.
超声（US）是一种有效的、可靠的影像学工具，可用于评估类风湿关节炎（RA）患者的关节和肌腱炎症、软骨和侵蚀。滑膜炎通常采用半定量评分方法，用于评估灰阶滑膜炎和能量多普勒活动，并且使用 US 评分图谱已显示出良好的可靠性。有几种评分方法显示对药物治疗有反应，但最佳的关节/肌腱评分仍有待探索。多普勒活动可以通过像素计数进行量化，血流可以通过阻力指数进行检查。与触诊引导相比，超声引导注射具有更好的耐受性和更高的疗效，因此应纳入风湿病学实践。不同的方法，如三维超声、对比增强超声和融合成像方法，都是未来可能用于治疗 RA 患者的超声方法。
