MRI findings in patients with blunt cervical trauma having a normal level of consciousness and normal CT reports

Abstract

Objective: This study investigates the possible magnetic resonance imaging (MRI) findings in patients with cervical trauma having a normal level of consciousness and normal CT reports. These patients have tenderness or an uncomfortable feeling in the traumatized area as well. Methods: In this cross-sectional anterograde study, cases were selected among patients referred to the emergency department of Hafte Tir, Iran University of Medical Sciences from 2012 to 2014. Inclusion criteria to select cases were: age above 15, blunt neck trauma, GCS=15, normal CT scan reports of neck, no past medical history of cervical vertebral surgery, and no persistent neurologic lesions. In order to analyse qualitative data, chisquare test was used and for quantitative data t test was applied accordingly. Results: Two hundred eighty patients with chief complaints of neck pain due to trauma entered our study. Among this batch, 264 of them had normal CT scan reports and MRI was done for all of them. According to the results, the maximum injury in MRI was related to intervertebral disc injury (38 cases), ligamentous edema (35 cases), and muscle edema (22 cases), respectively. Neck tenderness from the beginning of the accident and transient neurologic signs had a significant role in MRI results (P < 0.05). Conclusion: In patients with acute cervical trauma having normal CT reports, MRI must be done in those with the average age of 45 or more, tenderness in the neck area, and in those with neurologic transient symptoms.
