目的：探讨3.0 T磁共振增强3D-Space-iso序列在全段脊神经根的显示及相应脊神经根病变的诊断价值。材料与方法搜集脊神经根病变患者15例，正常志愿者3例，进行常规MRI序列扫描，冠状位非增强及增强3D-Space-iso序列，后两者均用3D最大信号强度投影做重建后处理，观察各序列显示脊神经根形态、大小及长度、走行与病变的关系。结果增强3D-Space-iso显示脊神经根、神经节及节后纤维较非增强3D-Space-iso及常规序列有更高的清晰度，能更清晰显示脊神经根病变及病变对脊神经根的压迫及侵犯程度。15例患者中腰椎间盘突出10例，肿瘤性病变3例，神经根鞘囊肿2例。结论增强3D-Space-iso序列对显示脊神经根解剖结构、以及与病变的解剖关系具有更大的优势，为临床诊治脊神经根病变提供明确的诊断依据。

Objective:To investigate the display technique and application value of 3.0 T magnetic resonance contrast enhanced 3D-Space-iso sequence in the entire segment spinal nerve roots lesions.Materials and Methods: Fifteen cases of patients with spinal nerve roots lesions and 3 cases of healthy volunteers were included. MRI conventional sequence, coronary 3D-Space-iso sequences (contrast enhanced and non-contrast enhanced) were performed in all cases. The source coronal images of 3D-Space-iso were further reconstructed using maxium intensity projection(MIP) technique. All displayed nerve roots were morphologically analyzed and the relation with lesions was evaluated.Results:Contrast enhanced 3D-Space-iso sequence has the best visualization than the other two sequences of spinal nerve roots spinal ganlfion, postganglionic neuroifbers and the degree of invasion and compression by the lesions. Among the 15 cases, there were 10 cases of disk herniation, 3 cases of tumor and 2 case of nerve root cysts.Conclusion:Contrast enhanced 3D-Space-iso sequence shows more advantages in displaying the internal structures of spinal nerve roots and the relation with lesions.It can provide deifnitely diagnostic basis for spinal nerve root diseases in clinical practice.
