Functional Magnetic Resonance Imaging Application and Its Clinical Significance in the Spondylotic Myelopathy
Abstract: Objective: To explore the functional magnetic resonance imaging application and its clinical significance in the spondylotic myelopathy. Methods: 10 cases spondylotic myelopathy patients treated in the orthopaedic department of our hospital from January 2014 to June 2014 were selected as the observation objects, and 10 cases healthy volunteers were selected as the control objects in the same period. Functional magnetic resonance imaging and the Japanese orthopaedic society of scoring system (JOA scores) evaluating the postoperative recovery were measured in the preoperative and postoperative 6 weeks, 3 months and 6 months, respectively. The control objects in the same period were measured by functional magnetic resonance imaging. Functional magnetic resonance imaging and JOA score and postoperative recovery (time step, action) were compared between two groups at different time points. Results: The limited areas of the cortex were activated at main motor areas on the side of the brain after completing the action in the control objects. Activation of cortical map area in functional magnetic resonance imaging of the spondylotic myelopathy patients widened compared with the healthy controls. Cortical activation mapping area reduced activation area and close to the healthy group after the spinal cord decompression. Compared with the control group, the occipital lobe, the frontal lobe and the limbic system were the areas of the brain that ReHo of the observation group patients significantly reduced. The cerebellum and the edge of leaf were the areas of the brain that ReHo of the observation group patients significantly increased. The JOA score and post-operation of the observation group are more significant than those of the control group (P < 0.05). Conclusion: Functional magnetic resonance imaging can be effective evaluation methods for the preoperative and postoperative cortical projection area changes in the spondylotic myelopathy patients’ cerebral cortex. We can evaluate the postoperative recovery and give positive postoperative rehabilitation guidance effectively with the functional magnetic resonance imaging assessment.
