| Abstract |
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 χ2 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). |

Attention Score in Context
This research output has an Altmetric Attention Score of 7. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 23 May 2018.
All research outputs
#4,235,611
of 23,070,218 outputs
Outputs from European Radiology
#477
of 4,181 outputs
Outputs of similar age
#93,609
of 443,258 outputs
Outputs of similar age from European Radiology
#13
of 79 outputs
Altmetric has tracked 23,070,218 research outputs across all sources so far. Compared to these this one has done well and is in the 80th percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 4,181 research outputs from this source. They receive a mean Attention Score of 4.6. This one has done well, scoring higher than 86% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 443,258 tracked outputs that were published within six weeks on either side of this one in any source. This one has done well, scoring higher than 77% of its contemporaries.
We're also able to compare this research output to 79 others from the same source and published within six weeks on either side of this one. This one has done well, scoring higher than 82% of its contemporaries.
