This 5-year longitudinal trial was conducted in follow-up to our initial trial which examined military breachers with MRI and EEG pre and post blast exposure.<h4>Purpose</h4>To examine brain MRI findings in military personnel exposed to multiple repeated blast exposures.<h4>Study type</h4>Five-year longitudinal prospective trial.<h4>Population</h4>Ninety-two males aged 23-42 with an average of 9.4 years of blast exposure.<h4>Field strength/sequence</h4>3 T brain MRI/T1-weighted 3D with reconstruction in three planes, T2-weighted, T2-weighted fluid attenuated inversion recovery (FLAIR) 3D with reconstruction in three plaJournal of magnetic resonance imaging : JMRIFive-Year Serial Brain MRI Analysis of Military Members Exposed to Chronic Sub-Concussive Overpressures.PMC11645495W6399‐15‐GB43W6399-15-GB43Glikstein RZhang TPortela de Oliveira EMelkus GBrun-Vergara MLRamsay TSchwarz BASkinner CfalseFive-Year Serial Brain MRI Analysis of Military Members Exposed to Chronic Sub-Concussive Overpressures.<h4>Background</h4>The Canadian Special Operations Forces Command conducts explosives operations and training which exposes members to explosive charges at close proximity.
