Evaluation of spinal trauma by multi detector computed tomography and magnetic resonance imaging

AbstractAim of workThe aim of this work is to assess the role of multi-detector computed tomography (MDCT) and magnetic resonance imaging (MRI) in evaluation of spinal trauma.Patients and methodsBetween January 2013 and April 2014, 98 patients (78 males and 20 females) with spinal injuries were investigated by MDCT and MRI. Assessment of the radiological findings of spinal injury was performed and the following were investigated: vertebral compression fractures, bursts and dislocations, posterior element fractures, C1 and C2 lesions, vertebral listhesis, bone marrow edema, spinal canal compression, disk herniation, extradural hematoma, spinal cord contusions, spinal cord swelling and posterior ligamentous complex injuries.ResultA total of 271 lesions were diagnosed as follows: 217 lesions were diagnosed using MRI alone, 1 54 lesions were diagnosed using MDCT alone and 100 lesions were diagnosed using MRI and MDCT conjointly. By using MRI 117 more lesions were detected than using MDCT. MRI was significantly superior to MDCT in the diagnosis of bone marrow edema, posterior ligamentous complex injuries, disk herniations, spinal canal compressions, and spinal cord contusions and edema. In cervical spine injuries, MRI was useful for the evaluation of the supporting ligaments and the spinal cord after the patient has been stabilized. The average times required to perform CT and MRI were 1.38±19.83 and 2.00±19.58days, respectively; this difference was significant (p⧹0.05) according to the Mann–Whitney test.ConclusionMRI was significantly superior to MDCT in the diagnosis of bone marrow edema, posterior ligamentous complex injuries, disk herniations, spinal canal compressions, and spinal cord contusions and edema. In cervical spine injuries, MRI was useful for the evaluation of the supporting ligaments and the spinal cord after the patient has been stabilized.MDCT and MRI are complementary to each other in evaluation of spine injuries
