US and MRI play a significant role in the diagnosis of rheumatic diseases and in monitoring treatment response. This systematic review summarises and evaluates available evidence on the value of low-field MRI compared to US in rheumatic diseases.
A computerised literature search was conducted by a single reviewer to identify relevant published articles on the diagnostic accuracy of low-field MRI compared to US in rheumatic diseases. The literature search comprised the period from January 1998 to September 2013.
The search yielded a total of 1055 articles that were reviewed by title or abstract; finally, 23 articles fulfilling all inclusion criteria were included in the analysis. Our results show that low-field MRI is probably more sensitive than US in the detection of erosions, due to its higher multiplanar capacity. In OA there was a good correlation between US and MRI measurements for cartilage thickness and for effusion in the superior and in the lateral recesses.
There are still few studies comparing US and low-field MRI for their diagnostic and prognostic value in rheumatology and it is currently difficult to draw any firm conclusions on the preferred imaging technique to answer specific clinical questions.
超声（US）和磁共振成像（MRI）在风湿性疾病的诊断和治疗反应监测中具有重要作用。本系统评价总结并评估了低磁场 MRI 与 US 在风湿性疾病中的应用价值。
由一名评审员进行计算机检索，以确定低磁场 MRI 与 US 在风湿性疾病中的诊断准确性的相关文献。文献检索时间为 1998 年 1 月至 2013 年 9 月。
共检索到 1055 篇文章，通过标题或摘要进行了初步筛选，最终有 23 篇符合所有纳入标准的文章纳入分析。我们的结果表明，由于低磁场 MRI 具有更高的多平面能力，因此在检测侵蚀方面可能比 US 更敏感。在 OA 中，US 和 MRI 测量关节软骨厚度以及上、外侧隐窝积液之间具有良好的相关性。
目前比较 US 和低磁场 MRI 在风湿病中的诊断和预后价值的研究较少，因此很难就哪种影像学技术更适合回答特定的临床问题得出确切的结论。
