Background And PurposePatients presenting with gunshot wounds (GSWs) to the neck are difficult to assess because of their injuries are often severe and they are incompletely evaluated by computed tomography (CT) alone. Our institution treats hundreds of patients with GSWs each year and we present our experience using magnetic resonance imaging (MRI) in the evaluation of cervical GSWs.Materials And MethodsFrom August 2000 to July 2012, all GSWs to the cervical spine treated at our institution were cataloged. Seventeen patients had 1 or more MRI studies of the cervical spine. Informed consent was obtained before MRI indicating the risks of retained metal fragments in the setting of high magnetic fields. CT scans were obtained before and after MRI to document any possible migration of metal fragments. We documented patients' neurologic examination results before and after MRI and at follow-up.ResultsPatients' age range was 18-56 years (mean 29.8 years). Eleven of 17 patients had retained metal fragments seen on CT scan, including 3 patients with fragments within the spinal canal. No patient experienced a decline in neurologic function after MRI. No migration of retained fragments was observed. Fifteen of 17 patients returned for follow-up examinations, with an average follow-up interval of 39.1 weeks (range, 1.3-202.3 weeks; median, 8 weeks).ConclusionFor carefully selected patients, MRI can be an effective tool in assessing GSWs to the neck and it can significantly improve the evaluation and management of this cohort. No patient in our series experienced a complication related to MRI.Copyright © 2015 Elsevier Inc. All rights reserved.
