ＭＲＩ对于急性及陈旧性脊髓损伤均有较高临床诊断价值，可直观地显示神经组织的多种病理改变，但在较轻型脊髓损伤的成像方面尚存在缺陷。本文将一组急性颈脊髓损伤动物模型的ＭＲＩ图像与组织切片进行观察对比，同时对所收集的２３例颈脊髓损伤临床资料进行分析。实验结果表明，ＭＲＩ对于脊髓实质水肿，大量出血以及中央管损伤甚为敏感，而对脊髓实质内点状或局灶状出血及神经细胞变性等不甚敏感，在判断蛛网膜下腔出血及硬膜外炎症变化方面也显不足。临床资料显示，ＭＲＩ难以将轻度脊髓损伤直接成像，但仍有助于判断病人的预后。对于重度脊髓损伤，ＭＲＩ则能清晰显示病灶的部位和大小，其所示损伤的程度与病人神经功能的丧失呈平行关系。 MRI has high clinical diagnostic value for acute and old spinal cord injury, which can intuitively show many pathological changes of nerve tissue, but there are still some defects in the imaging of mild spinal cord injury. In this paper, MRI images and tissue sections of a group of acute cervical spinal cord injury animal models were observed and compared, and the clinical data of 23 cases of cervical spinal cord injury collected were analyzed. The experimental results show that MRI is very sensitive to spinal edema, massive hemorrhage and central tube injury, but not sensitive to spot or focal hemorrhage and nerve cell degeneration in spinal plexus. In judging subarachnoid hemorrhage and hard Changes in extra-membranous inflammation are also inadequate. Clinical data show that MRI is difficult to direct imaging of mild spinal cord injury, but still help to determine the prognosis of patients. For severe spinal cord injury, MRI is able to clearly show the location and size of the lesion, which shows the degree of damage in parallel with the loss of neurological function in patients.
