Abstract
- <bold>Objectives: </bold>To perform an online survey about the use of magnetic resonance arthrography (MRA) in clinical practice.<bold>Methods: </bold>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.<bold>Results: </bold>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).<bold>Conclusions: </bold>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.<bold>Key Points: </bold>• 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).
