Background: Magnetic resonance imaging (MRI) is the modality of choice for evaluation of ligamentous and other spinal cord, soft tissue structures, disc, and occult osseous injuries. Objective evaluate the role of MRI as a non-invasive diagnostic tool in patient with spinal trauma.Methods: This study was conducted in department of radiodiagnosis, Sri Aurobindo institute of medical sciences and PG institute, Indore and approval from the ethical and research committee. The duration of this study was April 2018 to May 2020. We included 60 patients of spinal trauma referred for MRI in this study.Results: In 32 (53.3%) patients the mode of injury was road traffic accidents, in 23 (38.3%) patients it was fall and in 5 (8.3%) patients the mode of injury was any other mode. There was significant difference seen between the MR cord hemorrhage, cord compression, and code transaction.Conclusions: MRI is an excellent modality for imaging of acute spinal trauma. Normal cord on baseline MRI predicts excellent outcome. When comparing patients with complete, incomplete spinal cord injury (SCI) and spine trauma without SCI, significant difference was seen in cord hemorrhage, cord transection, cord compression.

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.

HIV-associated vacuolar myelopathy, or AIDS-associated myelopathy, is a rare initial presentation of HIV. One of the common HIV-associated neurocognitive disorders, HIV-associated vacuolar myelopathy presents with advanced immunosuppression in patients and is frequently associated with dementia. However, most cases are subclinical with characteristic findings identified through physical examination and/or imaging modalities. HIV-associated vacuolar myelopathy is characterized by progressive spastic paraparesis, gait disturbance and lower extremity sensory abnormalities including vibratory sensation. Magnetic resonance imaging findings in the spinal cord are abnormal in some patients with HIV-associated myelopathy, characteristically showing spinal cord atrophy at the level of the thoracic spine, but they may also be normal. Unfamiliarity with this as initial presentation of HIV infection may lead to failure to diagnose and intervene appropriately. We present a case of newly diagnosed HIV with myelopathy and dementia with minimal spinal cord involvement on magnetic resonance imaging.

ABSTRACT:Eighteen adult patients presenting with acute transverse myelitis (ATM) were evaluated using magnetic resonance imaging. Only 7 had abnormal scans showing an area of increased signal intensity within the cord solely on T2 weighted images; Tl weighted images were normal. The MRI abnormality did not correlate with the cause of the transverse myelitis, the extent of maximum neurological deficit, or the prognosis. A scan performed more than 5 days after the onset of disease was most likely to be positive. Even though the prognostic value of MRI in ATM may be limited, it remains a valuable technique for ruling out other causes of noncompressive spinal cord lesions, such as hemmorhage, vascular malformation, or tumor.
