ConclutionDTI may be more sensitive in pristine wallerian degeneration of spinal cord compression and can reflact the degree of injury of spinal cord compression.DTI is more precise checking method and can provide valuable information of quantization for earlier diagnosis of spinal cord compression in vivo.

结论磁共振弥散张量成像技术对脊髓受压损伤早期发生的华勒氏变性改变较敏感，并能反应其受压损伤程度，是目前早期活体诊断脊髓受压损伤比较准确的检查方法，对脊髓压迫症能提供有价值的量化信息。

There are some AChR plaques of morphological abnormality, and no contact sites of N-CAM with AChR although the intensity and scope of N-CAM staining is increased.D: Yiqi Huayu Recipe-treated group on the 20th day after L5 nerve root compression. All the AChR sites are reoccupied by N-CAM and the morphology of AChR are restored. E: Untreated group on the 30th day after lumbar nerve root compression. AChR plaques display irregularity in shape, with a few round or spindle shaped cupulae. Meanwhile, some N-CAM stainings are still shown to be around the AChR.
