摘　　要：目的:应用MRI平衡式稳态自由进动(Balance SSFP)序列成像多平面重建描述椎管内臂丛正常形态解剖。材料与方法:本组20例自愿者行MRI检查;从283例同时行CTM和MRI检查中筛选CTM未见椎管内臂丛神经根结构损伤的28例与MRI比较。行冠状、矢状及斜横轴位重建,测量20例自愿者各组神经根。结果:冠状图像显示完整的神经前、后根结构,前根表现为"机翼状",后根表现为"毛刷状";矢状位脊髓旁层面显示各组神经根与相应椎体位置关系;斜横轴位图像显示神经根连续性更完整,避免了上下组神经根重叠。结论:应用Balance-SSFP序列成像,冠状位、矢状位及斜横轴位重建图像,可提供更多的椎管内臂丛的形态解剖学信息。Objective：To delineate normal morphology and anatomy of nerve roots of brachial plexus within the spinal canal on the multiplanar reconstruction images of 3-D balance steady state free precession（balance SSFP）.Methods：Twenty cases of normal volunteers and 28 cases in which no abnormal appearance of CTM coming from a consecutive 283 cases were evaluated by 3-D balance SSFP sequence on coronal,sagittal and oblique axial reconstructive images and some data of the nerve roots,20 cases of normal volunteers were measured.Results：A coronal image clearly demonstrated all of the nerve roots and described the ventral roots as a wing-like configuration and the dorsal roots as a brush-like configuration.A sagittal image on paraspinal cord demonstrated all of the nerve roots and the locating relationships of the upper and lower nerve roots with the corresponding vertebra body.Oblique axial image might display a more continuous roots than one on conventional axial image.Conclusion：Coronal,sagittal and oblique axial reconstructive of 3-D balance-SSFP sequence images was helpful in obtaining more information about the morphology and anatomy of nerve roots of brachial plexus within spinal canal.
