High-resolution surface-coil MR imaging reveals intricate anatomic detail of the cervical spinal canal and its neurovascular contents. Appreciation of the normal neurovascular anatomy provides a scientific foundation for the detection of disease. Sagittal, axial, and oblique MR images of normal subjects were correlated with comparable anatomic sections obtained with a cryomicrotome whole-organ sectioning technique. The anterior epidural venous plexus is a prominent structure in the cervical spinal canal and was consistently identified both with cryomicrotomy and with MR in sagittal and axial planes. Epidural veins can be displaced and distorted in patients with cervical disk disease. Nerve roots including dorsal and ventral rootlets were consistently identified on axial images coursing through the subarachnoid space. Oblique-plane imaging showed nerve roots "en face" in their respective foramina; this may be a useful imaging technique in the diagnosis of nerve root impingement.
高分辨率表面线圈磁共振成像可揭示颈椎管及其神经血管内容物的精细解剖细节。了解正常神经血管解剖结构为疾病检测提供了科学基础。正常受试者的矢状面、轴位面和斜位磁共振图像与通过冷冻切片全器官切片技术获得的可比解剖切片进行了对照。硬膜外前静脉丛是颈椎管内的一个突出结构，在矢状面和轴位面上通过冷冻切片术和磁共振成像均能持续识别。颈椎间盘疾病患者的硬膜外静脉可发生移位和变形。在穿过蛛网膜下腔的轴位图像上可始终识别出包括背根和腹根丝的神经根。斜位成像可显示神经根在各自椎间孔内的“正面”图像；这可能是诊断神经根受压的一种有用成像技术。
