The objective of this case series is to present the findings following gradient echo T2-weighted MRI (SWI) upon clinical evaluation after a concussion in 4 young professional motocross racers.\n Clinical Findings: Microhemorrhages were found in 2 of 4 riders. Areas of microhemorrhages were not aligned with a previously positive CT finding from a prior concussion in 1 rider.\nConclusions: Microhemorrhages were found in 2 young motocross riders following a gradient echo T2-weighted MRI upon a clinical evaluation after a concussion. Long-term consequences of these findings are not yet known, and longitudinal studies are needed to provide further understanding to improve concussion management in motocross athletes.<\/jats:p>","DOI":"10.36518\/2689-0216.1011","type":"journal-article","created":{"date-parts":[[2020,10,31]],"date-time":"2020-10-31T06:16:16Z","timestamp":1604124976000},"source":"Crossref","is-referenced-by-count":0,"title":["Microhemorrhages in Professional Motocross Athletes: A Case Series"],"prefix":"10.36518","volume":"1","author":[{"given":"Brianna","family":"Millsaps","sequence":"first","affiliation":[{"name":"University of Central Florida"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Phillip R.","family":"Worts","sequence":"additional","affiliation":[{"name":"Department of Nutrition, Food and Exercise Sciences, Florida State University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Scott O.","family":"Burkhart","sequence":"additional","affiliation":[{"name":"Department of Orthopedics and Sports Medicine, Children's Health Andrews Institute"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David C","family":"Berg","sequence":"additional","affiliation":[{"name":"Tallahassee Orthopedic Clinic"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"22435","published-online":{"date-parts":[[2020,10,30]]},"container-title":["HCA Healthcare Journal of Medicine"],"original-title":[],"language":"en","deposited":{"date-parts":[[2026,11,6]],"date-time":"2026-11-06T09:34:03Z","timestamp":1793957643000},"score":1,"resource":{"primary":{"URL":"https:\/\/scholarlycommons.hcahealthcare.com\/hcahealthcarejournal\/vol1\/iss5\/3"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020,10,30]]},"references-count":0,"journal-issue":{"issue":"5","published-online":{"date-parts":[[2020,10,30]]}},"URL":"https:\/\/doi.org\/10.36518\/2689-0216.1011","relation":{},"ISSN":["2689-0216"],"issn-type":[{"value":"2689-0216","type":"electronic"}],"subject":[],"published":{"date-parts":[[2020,10,30]]}}}
