The aim of this study was to reveal the techniques and findings of the 3D fast asymmetric spin echo (3D FASE) sequence for imaging the cisternal segment of the normal abducent nerve.
Ten healthy volunteers were examined using the 3D FASE sequence, and oblique coronal and oblique sagittal images were reconstructed according to the specific course of the abducent nerve.
The abducent nerve was identified with certainty and displayed on the oblique coronal and oblique sagittal reconstructed images in 80% of cases using Dorello's canal as landmark. The bilateral nerve of one case and unilateral nerve of two cases could not be identified and displayed. The mean diameter of the cisternal segment was 1.39 mm on 3D FASE image.
The 3D FASE sequence can be used to image the cisternal segment of the abducent nerve with Dorello's canal as a landmark.
本研究旨在揭示用于正常展神经脑池段成像的三维快速非对称自旋回波（3D FASE）序列的技术及表现。
对10名健康志愿者采用3D FASE序列进行检查，并根据展神经的特定走行重建斜冠状位和斜矢状位图像。
以Dorello管为标志，80%的病例在斜冠状位和斜矢状位重建图像上能明确识别并显示展神经。1例双侧神经及2例单侧神经无法识别和显示。3D FASE图像上脑池段展神经的平均直径为1.39mm。
3D FASE序列可用于以Dorello管为标志对展神经脑池段进行成像。
