To demonstrate that currently available magnetic resonance imaging techniques may verify the absence of the abducens nerve in Duane syndrome.
We performed magnetic resonance imaging in a 36-year-old woman with left Duane syndrome, type 1, using spoiled gradient recalled acquisition in the steady state to obtain high-resolution T1-weighted images through the abducens nerve in its subarachnoid segment. Scans were obtained in the axial plane from the medulla to the midbrain and then reformatted along the plane of the abducens nerve.
Unilateral absence of the left abducens nerve was verified using magnetic resonance imaging.
The absence of the abducens nerve in Duane syndrome can be verified by modern magnetic resonance imaging techniques.
证明目前可用的磁共振成像技术可证实杜安综合征中展神经缺失。
我们对一名36岁患有1型左侧杜安综合征的女性进行了磁共振成像检查，采用稳态扰相梯度回波采集序列，以获取穿过蛛网膜下腔段展神经的高分辨率T1加权图像。扫描在轴位平面上从中脑延髓部至中脑进行，然后沿展神经平面进行重组。
通过磁共振成像证实左侧展神经单侧缺失。
现代磁共振成像技术可证实杜安综合征中展神经的缺失。
