Abstract:

Objective

To investigate the applying value of 3D-FIESTA+c MRI sequences for cranial nerves Ⅰ-Ⅻ.

Methods

3D-FIESTA+c as used in 20 volunteers and 20 patients with complaint of cranial nerves.480 nerves were evaluated. Two radiologists independently divided the imaging findings in to 3 grades: completely visualized,partially visualized,and not visualized. The first two grades were defined as visualization and the last grade was no visualization.The relationship between nerves and surrounding vessels were divided into grades:notcontact, contact, compression.

Results

The rate of visualization of these cranial nerves with 3D-FIESTA+C sequences were as follows respectively: nerveⅠ (84.3%); nerve Ⅱ (100%); nerve Ⅲ(100%); nerve Ⅳ(43.8%); nerve Ⅴ(100%); nerve Ⅵ(100%); nerve Ⅶ(100%); nerve Ⅷ(100%); nerve Ⅸ-Ⅺcomplex(100%); nerve Ⅻ(47.1%).16 of 20 patients with complaint of cranial nerves displayed nerve had vascular compression or contact.

Conclusions

3D-FIESTA+c sequence can show detailed anatomy of the cranial nerves and relationship between nerves and surrounding vessels,to help clinical treatment.
