150例脊柱侧弯畸形患者的MRI和X线平片对照研究

摘要

Objective To evaluate the clinical application of MRI and X-ray in scoliosis diagnosis. Methods 150 cases oi scoliosis were collected from March 2009 to December 2009 in our hospital, and theMRI and X-ray imaging performance were compared. Results Among the 150 cases of patients, X-ray plain film detection of vertebral bone deformity in 19 cases,MRI detected vertebral bone deformity in 18 cases; MRI detected expansion of the central canal in 9 cases, syringomyelia in 5 cases,Chiari deformity in 9 cases, neurofibromatosis in 1 case,tethered syndrome in 2 cases. Differences in detection oi central canal expansion,syringomyelia, and Chiari deformity between MRI and X-ray were statistically significant. Conclusion X-ray advantages are convenient, inexpensive; while its drawback is that two-dimensional stack image. MRI shows good efiect on the soft tissue lesions; while its disadvantage is slow scanning, metal artifacts, and contraindications of some patients.%目的 对磁共振成像(MRI)和X线平片在脊柱侧弯畸形诊断中的作用进行对比.方法 收集2009年3 ～12月于我院诊治的150例脊柱侧弯患者,对其MRI及X线平片的影像表现进行比较.结果 150例患者中,X线平片检出椎体骨质畸形19例,MRI检出椎体骨质畸形18例;MRI检出中央管扩张9例,脊髓空洞5例,Chiari畸形9例,神经纤维瘤病1例,栓系综合征2例.磁共振与X线平片在检出中央管扩张、脊髓空洞、Chiari畸形方面比较,差异具有统计学意义.结论 X线平片的优点是方便、价廉;缺点是不能展示椎体的三维结构.MRI对软组织病变显示效果好;缺点是扫描速度慢、易受金属伪影影响、部分患者存在禁忌证.
