Conventional 3T MRI was used to evaluate 127 prospectively enrolled PCS patients and 29 controls for non-specific white matter hyperintensities (WMH) and traumatic structural lesions, including encephalomalacia, atrophy, microhemorrhage, subarachnoid hemorrhage, and cortical siderosis. All PCS patients had a clinical diagnosis of one or more concussions based on the Concussion in Sport Group (CISG) consensus statements. Patients with recognized intracranial hemorrhage on prior head computed tomography (CT) and MRI were excluded. The differences between the PCS and control groups were analyzed. Four patients in the PCS group (3.1%) had positive findings, which included microhemorrhages in two patients and encephalomalacia in another two patients. None of these lesions was present in the control group, but there was no statistical difference between the two groups (\n                    <jats:italic toggle=\"yes\">p<\/jats:italic>\n                    \u2009=\u20090.5 for microhemorrhage and\n                    <jats:italic toggle=\"yes\">p<\/jats:italic>\n                    \u2009=\u20090.5 for encephalomalacia). In the PCS group, 28 patients (22%) had WMH (15.7% had 1\u201310 lesions and 6.3% had &gt;10 lesions), and these results did not differ from the age-matched control (20.6%, all with 1\u201310 lesions;\n                    <jats:italic toggle=\"yes\">p<\/jats:italic>\n                    \u2009=\u20090.9) The location of the WMH showed no significant difference in the number of juxtacortical WMH between the PCS and control groups (\n                    <jats:italic toggle=\"yes\">p<\/jats:italic>\n                    \u2009=\u20090.5). Structural lesions were rare in PCS in this study, and the presence of such findings suggests a more severe form of traumatic brain injury. Our data support the role for MRI in the diagnosis of PCS by exclusion of atrophy, encephalomalacia, and all forms of intracranial hemorrhage. The presence of WMH irrespective of number is not an exclusion. This is the first description of the MRI criteria for PCS.\n                  <\/jats:p>","DOI":"10.1089\/neu.2019.6809","type":"journal-article","created":{"date-parts":[[2019,12,11]],"date-time":"2019-12-11T02:45:11Z","timestamp":1576032311000},"page":"1190-1196","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":27,"title":["Magnetic Resonance Imaging Criteria for Post-Concussion Syndrome: A Study of 127 Post-Concussion Syndrome Patients"],"prefix":"10.1177","volume":"37","author":[{"given":"Jyoti","family":"Panwar","sequence":"first","affiliation":[{"name":"Department of Radiology, Christian Medical College, Vellore, India."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Charlie Chia-Tsong","family":"Hsu","sequence":"additional","affiliation":[{"name":"Department of Medical Imaging, Gold Coast University Hospital, Brisbane, Southport, Australia."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Charles H.","family":"Tator","sequence":"additional","affiliation":[{"name":"Division of Neurosurgery, Department of Surgery, Toronto Western Hospital, Toronto, Ontario, Canada."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David","family":"Mikulis","sequence":"additional","affiliation":[{"name":"Division of Neuroradiology, Department of Medical Imaging, University of Toronto, Toronto, Ontario, Canada."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2020,5,5]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.15585\/mmwr.ss6609a1"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1001\/jama.2013.169158"},{"key":"e_1_3_3_4_2","first-page":"1","article-title":"Surveillance for traumatic brain injury-related deaths\u2014United States, 1997\u20132007","volume":"60","author":"Coronado V.G.","year":"2011","unstructured":"Coronado V.G., , Xu L., , Basavaraju S.V., , McGuire L.C., , Wald M.M., , Faul M.D., , Guzman B.R., , Hemphill J.D., , and Centers for Disease Control and Prevention (2011).
