AMSSM LIBRARY OF SPORTS ULTRASOUND PATHOLOGY
Objective The Sports Ultrasound Committee looks to create an educational resource directed at residents, fellows, and other learners to review both common and unusual pathology within sports ultrasound using case examples. In exploring the library of sports ultrasound pathology, we intend for learners to gain an appreciation for the nuances of ultrasound imaging and increased confidence in recognition of abnormal findings. Submission Guidelines Current sports medicine fellows are particularly encouraged to submit, with faculty guidance. If a trainee is preparing the submission, the content should be reviewed with a local attending to verify ultrasound image quality and image interpretation accuracy. Following submission, a secondary review will be performed by an AMSSM subcommittee. Edits may be suggested or if images are of low quality, the case may be rejected. Thereafter, the accepted content will be posted and available for member review. All content must be de-identified prior to submission. High quality images and/or videos should be submitted. Low quality images will not be accepted. US Pathology Submission Guidelines – a quick reference guide to a successful submission.
