Aim.To evaluate the role of magnetic resonance imaging (MRI) as a diagnostic method in children with acute trauma of the cervical spine and spinal cord, to compare the correspondence of MRI results with neurologic symptoms in accordance with the ASIA scale.Materials and methods.156 children with acute trauma of spine and spinal cord at the age from 6 months up to 18 years were studied. MRI was performed on a Phillips Achieva 3T scanner. The standard protocol included MYUR (myelography) in coronal and sagittal projections, STIR and T2VI FS SE in sagittal projection, T2VI SE or T2 * VI FSGE (axial projection), 3D T1VI FSGE before and after contrast enhancement. Contrast substance was injected intravenously in the form of a bolus at the rate of 0.1 mmol/kg (equivalent to 0.1 ml/kg) at a rate of 3 to 4 ml.Results.The causes of cervical spine blunt trauma were: road accidents (55), catatrauma (60), “diver” trauma (21), blunt trauma (20). Intramedullary lesions of the spinal cord were detected: concussion (49), bruising / crushing (27), hematomia (34), disruption with divergence of segments (21), accompanied by edema (141); extramedullary lesions: epi- and subdural, intralesive and sub-connective and soft tissues hematomas (68), ruptures of bundles (48), fractures (108), dislocation and subluxation of the vertebrae (35), traumatic disc herniation (37), spinal cord compression and/or rootlets (63), statics violation (134), instability (156).Conclusion.MRI is the optimal method for spinal cord injury diagnostics. In the acute period of injury this technique has limited application, but it can however serve as a primary diagnostic method in these patients. MRI should be performed no later than the first 72 hours after injury. The most optimal for visualization of cervical spine trauma and spinal cord are T2VI SE and STIR in sagittal projection with suppression of signal from fat. MRI results correlate with neurologic symptoms at the time of performance according to the ASIA scale, and therefore MRI should be performed in all patients with acute cervical spine trauma, whenever possible.
