磁共振三维FIESTA技术在脊柱畸形疾病的初步临床应用

目的:探讨磁共振三维FIESTA技术在脊柱畸形疾病的初步临床应用价值。方法:搜集脊柱畸形患者70例,35例后凸畸形,35例侧凸畸形。均采用GE1.5T超导磁共振机。扫描序列包括:二维横轴位,冠状位,矢状位分别行FSET2WI扫描及三维冠状位,矢状位FIESTA扫描。结果:35例后凸畸形的患者得到矢状位,并以其为定位像扫描得到横轴位后才能显示出标准脊髓。35例侧凸畸形的患者得到冠状位,并以其为定位像扫描得到横轴位后才能显示出标准脊髓。70例又行三维矢或冠状位FIESTA扫描,依脊柱为后凸或侧凸的畸形特点而定,选择FIESTA扫描方式,可重建得到多层面多角度的冠或矢状位像、横轴位像及清晰真实的矢或冠状位像。结论:磁共振扫描可清晰显示脊柱畸形的脊髓,磁共振三维FIESTA扫描可快速、多角度、多层面连续显示脊柱畸形的脊髓,更好指导临床手术。

Application of MR 3D FIESTA Technology in Spinal Malformation

Objective To study the value of MR 3D FIESTA technology in spinal malformation. Materials and Methods 70 patients with spinal malformation and GE 1.5T superconducting MR machine got involved in. The scanning sequences included FSET2WI scanning at 2D axial position, coronal position and sagital positon, and FIESTA scanning at 3D coronal position and sagital position. Results FIESTA scanning could be used in the achievement of multi-slice and multi-angle coronal, sagital and axial images. Conclusion 3D MR FIESTA can be applied to rapid, multi-angle, multi-slice and continuous display of the spinal cord.
