To perform an online survey about the use of magnetic resonance arthrography (MRA) in clinical practice.
We administered an online survey to all 1,550 members of the European Society of Musculoskeletal Radiology (ESSR) about MRA asking ten different questions. Subgroup analysis was performed between general and orthopaedic hospitals using χ and Mann-Whitney U statistics.
One-hundred forty-eight answers were included (148/1,550, 9.5% of ESSR members). A median of 3,000 (interquartile range: 1,567.5-5,324.5) musculoskeletal MR examinations and a median of 125.5 MRAs (50.75-249) per institution were performed in 2016. Ratio between MRA and musculoskeletal MR was 4.7% (1.6%-9.0%). Using MRA, the most investigated joint was the shoulder followed by the hip (96.6%). The most common indications were the evaluation of instability, labrum, and rotator cuff (85.1%). Fluoroscopy represented the preferred injection guidance. A self-prepared mixture of Gadolinium/saline is preferred in general hospitals, while pre-diluted Gadolinium-based syringes are mainly used in orthopaedic hospitals (P=.010). The number of MRA performed at orthopaedic hospitals (284;83.75-449.50) was higher (P=.006) than that performed at general hospitals (115.50;44.75-234.25).
One out of twenty MR examinations is a MRA, with higher prevalence in orthopaedic hospitals. The shoulder and the hip are the most investigated joints. Instability, labrum, and cuff are the most common indications.
• The most common MRAs are shoulder and hip (96.6% of answers). • Most common clinical indications for MRA are instability, labrum, and rotator cuff (85.1% of answers). • Fluoroscopy represents the preferred guidance to inject joints (61.0% of answers). • The median number of MRA performed at orthopaedic hospitals (n=284) was significantly higher (P=.006) than that performed at general hospitals (n=115.50). • A self-prepared mixture of Gadolinium/saline solution is preferred in general hospitals (64.8%) compared to orthopaedic hospitals (36.0%; P=0.010).
对磁共振关节造影术（MRA）在临床实践中的应用进行在线调查。
我们向欧洲肌肉骨骼放射学会（ESSR）的 1550 名成员发送了一份关于 MRA 的在线调查问卷，共提出了十个不同的问题。使用 χ 和曼-惠特尼 U 检验对综合医院和骨科医院进行了亚组分析。
共纳入 148 份答卷（ESSR 成员的 148/1550，9.5%）。2016 年，每家机构平均进行 3000 次（四分位间距：1567.5-5324.5）肌肉骨骼磁共振检查和 125.5 次（50.75-249）MRA。每个机构的 MRA 与肌肉骨骼磁共振检查的比例为 4.7%（1.6%-9.0%）。使用 MRA 检查的最常见关节是肩部，其次是髋关节（96.6%）。最常见的适应证是评估不稳定、盂唇和肩袖（85.1%）。透视引导是最常用的注射方法。在综合医院中，更倾向于使用自行配制的钆/盐水混合物，而在骨科医院中，更倾向于使用预稀释的基于钆的注射器（P=.010）。骨科医院进行的 MRA 数量（284；83.75-449.50）高于综合医院（115.50；44.75-234.25）（P=.006）。
每 20 次磁共振检查中就有 1 次是 MRA，在骨科医院中更为常见。肩部和髋关节是最常检查的关节。不稳定、盂唇和肩袖是最常见的适应证。
