Comparative study of MR 3 D-SPACE and 3 D-TOF sequences in diagnosis of intracranial neurovascular compression syndrome / 实用放射学杂志

ABSTRACT

Objective To investigate the value of fused 3D-SPACE and 3D-TOF images in diagnosis of intracranial neurovascular compression syndrome.Methods 26 patients with intracranial neurovascular compression syndrome were examined using 3D-SPACE sequence and 3D-TOF sequence.After 3D-SPACE and 3D-TOF were fused by different times,the quality of image as well as the ability of j udging the relationship between nerves and blood vessels was analyzed and compared between the original images and the fused images.Results In this study,the fused images by adding one 3D-SPACE sequence and one 3D-TOF sequence showed the highest accurate than others(2 1 cases),and the j udgement of the relationship between the responsible blood vessels and nerve accor-ded with the surgical results to the highest extent (P<0.05).Conclusion The fusion image of 3D-SPACE sequence and 3D-TOF se-quence can improve the diagnostic ability of the intracranial neurovascular compression syndrome,and the appropriate proportion of the fusion image can show the relationship between the nerve and blood vessel.
