[Abstract] 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 ganflion, postganglionic neurofibers 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 definitely diagnostic basis for spinal nerve root diseases in clinical practice.
