Utility of Magnetic Resonance Arthrography in the Age of Expanded Magnetic Resonance Imaging Capabilities: A Global Survey Perspective.

Background Magnetic resonance imaging (MRI) arthrography has been a mainstay in the diagnosis of musculoskeletal (MSK) joint-related pathology for decades. With the advent of MRI and further advancements incorporating powerful magnetic fields, the radiological landscape is undergoing a shift. The objective of this study is to evaluate the relevance and preference for MRI arthrography versus MRI among MSK radiologists in our current clinical practice across a range of geographic locations. Methods A global survey of 52 MSK radiologists was conducted to understand current practices, preferences, and recommendations related to the adoption of MRI arthrography and advanced MRI technologies. Responses were analyzed using descriptive statistics, and significant trends were compiled to present the overall preferences of the participants from their clinical experience. Results The majority of the respondents were from the UK (65%), followed by India (13%), the United States (11.5%), and the United Arab Emirates (8%). Of the radiologists surveyed, 98% currently perform MRI arthrogram procedures within their practice, with 27% of clinicians conducting more than 100 MRI arthrogram procedures annually. Regarding the adoption of 3T MRI scanners, 79% of respondents affirmed they have access to the technology within their respective institutions. Concerning the choice of contrast agents used, 84% preferred dilute gadolinium, 8% used saline, 4% used both gadolinium and saline, and another 4% opted for alternative agents. Despite the growing accessibility and utility of 3T MRI, MRI arthrograms remain a favored procedure, especially for shoulder pathology and postoperative cases. For the hip and wrist, the preference leans toward 3T MRI, except for more complex diagnostic purposes or postoperative cases. Conclusions The study's findings suggest that while the advent of the 3T MRI has impacted the frequency with which MRI arthrograms are conducted, it cannot entirely replace the precision and specificity MRI arthrography offers for particular joint pathologies. As institutions expand upon their MRI and imaging infrastructure, further research in this area may help guide MSK radiologists in selecting the most appropriate imaging modality for patients on a case-by-case basis.
