Cervical spondylotic myelopathy, degenerative cervical disc herniation lead to spinalcord compression or spinal cord ischemia, followed by spinal cord dysfunction, highincidence in the population over the age of40, the is cervical disease hazard is the mostserious type. For conventional imaging diagnosis of cervical spondylotic myelopathycervical magnetic resonance imaging, can clearly show the oppressed cervical lesions withneighboring organizational relationships and signal changes. However, conventional MRI inthe diagnosis of CSM to get up early sensitivity is relatively low, and underestimated thedegree of injury, to assess spinal cord function state from the microscopic point of viewcannot be changed. Currently, the lack of clinical imaging methods based on the objective ofthe change of the spinal cord itself.Magnetic resonance imaging is recognized at home and abroad the best means ofdiagnosis of CSM, T2WI spinal cord signal is an important means of MRI diagnosis of spinal cord degeneration, and for patients with early CSM, T2WI often no abnormalperformance cannot be earlier CSM spinal cord injury and lesions make the appropriatejudgment. Diffusion tensor magnetic resonance imaging through the diffusion motion ofwater molecules in the spinal cord in all directions, using its diffusion gradient on diffusionof water molecules in the spinal cord to quantify, fully reflects the microscopic changes tothe spinal cord, the path physiological changes. Therefore, seeking a change based on spinalcord function, safe, non-invasive, objective and accurate diagnostic method is of greatsignificance for the cure of patients with cervical.Objective To qualitative and quantitative analysis of diffusion tensor magnetic resonanceimaging characteristics of patients with cervical myelopathy explore patients with cervicalmyelopathy the imaging features and nerve function evaluation DTI value in the diagnosis ofCSM.Methods To collect30patients with approximate cervical spondylotic myelopathy based onthe inclusion and exclusion criteria.3.0T MRI machine conventional MRI and DTI scans ofpatients included, the FA and ADC values of the lesion and normal areas analyzed, and thepatients ODI score and JOA score.Result All patients were completed examination,14patients with spinal cord lesions T2WIhigh signal-positive patients had the lesion ADC value was significantly higher than thenormal area, FA values significantly lower than normal area;13cases of spinal cord lesionsthe T2WI negative patients the ADC value of the lesion was significantly higher than thenormal area, FA values significantly lower than the normal area; no significant change in theADC value and FA value of3patients with spinal cord lesions T2WI negative patients.Conclusion DTI imaging technology can be more sensitive to the change of the microscopicpathology of the spinal cord and nerve function changes the results with clinical assessmentscale has consistency, is expected to become a new judgment measure of evaluation of theseverity of spinal cord injury. |
