This study was done to (1) determine the prevalence of parenchymal brain microhemorrhages (MH) using susceptibility weighted imaging (SWI) in children with NAT and (2) assess whether the presence of parenchymal MH resulted in improved prediction of long-term neurologic outcome. A retrospective analysis of head CT and MRI findings in 118 pediatric NAT victims was performed. Logistic regression in patients with 6 month or greater neurologic followup was done to determine if the presence of MH on SWI was predictive of long term outcome.
