Needs Assessment of Musculoskeletal Ultrasound Training in North American Pediatric Rheumatology Fellowship Programs.

This study demonstrates that North American pediatric rheumatology fellows have a strong interest in learning MSUS, but they face significant challenges in accessing MSUS training (lack of MSUS-trained faculty, time and access to hands-on training). MSUS should be incorporated into fellowship curriculum, however implementation remains a challenge.
