This study is a retrospective review of 103 pediatric patients who underwent initial head CT and subsequent follow-up rapid MR imaging between January 2010 and July 2013. Patients had minor head injuries that required imaging. There was almost perfect agreement in the ability to detect extra-axial hemorrhage on rapid MR imaging and CT (kappa = 0.84). Evaluation of hemorrhagic contusion/hemorrhage demonstrated a moderate level of agreement between MR imaging and CT (kappa = 0.61). The authors conclude that rapid MRI is an adequate imaging technique for the follow-up of pediatric patients with minor head trauma.
