PURPOSE
To compare the MR characteristics of the oculomotor nucleus with its appearance on anatomic images.
METHODS
Specimens of cadaveric brains were imaged in a 3.0-T MR imager equipped with a 3.0-cm solenoid coil. The specimens were sectioned, stained, and examined histologically. On anatomic sections, the oculomotor nuclei, medial longitudinal fasciculus, red nuclei, and oculomotor nerve were identified. The MR images were then compared with the anatomic sections.
RESULTS
The oculomotor nuclei, medial longitudinal fasciculus, red nuclei, and oculomotor nerve could be identified on MR images by their size, shape, signal intensity, and location.
CONCLUSION
MR images show the anatomic relationship of the oculomotor nerve complex, medial longitudinal fasciculus, and related structures in the brain stem.
目的
比较动眼神经核在磁共振成像（MR）上的特征与其在解剖图像上的表现。
方法
在配备3.0厘米螺线管线圈的3.0-T MR成像仪中对尸体脑标本进行成像。将标本切片、染色并进行组织学检查。在解剖切片上，识别出动眼神经核、内侧纵束、红核和动眼神经。然后将MR图像与解剖切片进行比较。
结果
动眼神经核、内侧纵束、红核和动眼神经可通过其大小、形状、信号强度和位置在MR图像上得以识别。
结论
MR图像显示了脑干中动眼神经复合体、内侧纵束及相关结构的解剖关系。
